Abstract
Mimosa tenuiflora (Willd.) Poir. (Fabaceae) is a plant native to Brazil and occurs in the phytogeographic domains of Caatinga and Cerrado. Relevant studies have investigated the chemical components of this plant and others have already demonstrated its teratogenic potential. It has been proven that this plant causes congenital malformations in farm animals and, consequently, financial losses to farmers in the Brazilian semiarid region. The present work aimed to carry out a bibliographic survey on the teratogenic effects of M. tenuiflora in ruminants and to group the chemical compounds occurring in this species. For this, databases were consulted and twenty-four articles published in the last 30 years (1990-2020) were included. According to the scientific documents analyzed, M. tenuiflora has embryotoxic, fetotoxic and abortive potential in farm animals, especially sheep and goats. The main classes of chemical compounds present in this species are alkaloids, saponins, flavonoids, and terpenoids. It is likely that some of these substances, mainly the indole alkaloid N,N-dimethyltryptamine, are related to the teratogenic effects reported in ruminants in the Brazilian semiarid region.

Abstract
Plant secondary metabolites (PSMs), such as alkaloids, are often found in many parts of a plant, including flowers, providing protection to the plant from various types of herbivores or microbes. PSMs are also present in the floral nectar of many species, but typically at lower concentrations than in other parts of the plant. Nectar robbers often damage floral tissue to access the nectar. By doing so, these nectar robbers may initiate an increase of PSMs in the floral nectar. It is often assumed that it takes at least a few hours before the plant demonstrates an increase in PSMs. Here, we addressed the question of whether PSMs in the floral tissue are immediately being released into the floral nectar following nectar robbing. To address this research question, we investigated whether there was an immediate effect of nectar robbing by the Palestine Sunbird (Nectarinia osea) on the concentration of nectar alkaloids, nicotine and anabasine, in Tree Tobacco (Nicotiana glauca). We found that the concentration of anabasine, but not nicotine, significantly increased in floral nectar immediately following simulated nectar robbing. These findings suggest that nectar robbers could be ingesting greater amounts of PSMs than they would if they visit flowers legitimately. As a consequence, increased consumption of neurotoxic nectar alkaloids or other PSMs could have negative effects on the nectar robber.

Abstract
Unlike most Nicotiana species, leaf tissues of the globally significant weed Nicotiana glauca Grah. (Argentinian tree tobacco) contains anabasine as the main component of its alkaloid pool, with concentrations typically increasing several fold in response to wounding of plants. The Δ(1)-piperidinium ring of anabasine is synthesised from cadaverine, via the decarboxylation of lysine, however the identity of the protein catalysing this reaction remains unknown. Recent studies indicate that ornithine decarboxylase (ODC), an enzyme involved in the synthesis of the diamine putrescine, may also possess LDC activity. Previously we found that ODC transcript is markedly up-regulated in leaves of N. glauca in response to wounding. In order to examine the role of ODC in the synthesis of anabasine in N. glauca, transcript levels were constitutively down-regulated in hairy root cultures and transgenic plants via the introduction of a CaMV35S driven ODC-RNAi construct. In addition to the anticipated marked reduction in nicotine concentrations, demonstrating that the ODC-RNAi construct was functioning in vivo, we observed that N. glauca ODC-RNAi hairy root cultures had a significantly diminished capacity to elevate anabasine synthesis in response to treatment with the wound-associated hormone methyl jasmonate, when compared to vector-only controls. We observed also that ODC-RNAi transgenic plants had significantly reduced ability to increase anabasine concentrations following removal of the plant apex. We conclude that ODC does have an important role in enabling N. glauca to elevate levels of anabasine in response to wound-associated stress.

Abstract
Plants were, and still are, widely used for a number of conditions affecting women in California. This article discusses traditional remedies of the Chumash for dysmenorrhea, premenstrual syndrome, feminine hygiene, heavy menstruation, urinary tract infections, parturition, lactation, infant care, menopause, sexually transmitted diseases, fertility, contraception and abortions. Many plants are presented including Artemisia douglasiana, Paeonia californica, Trichostema lanatum, Salvia apiana, Ephedra viridis, Leymus condensatus, Vitis californica, Eschscholzia californica, Rosa californica, Scirpus acutus, Anemopsis californica and Phoradendron macrophyllum. By providing the specific uses of plants for specific diseases and discussing chemistry, efficacy and safety concerns for each plant, we hope that this article gives direction to women seeking to use plants in their health care.

Abstract
The induction of cleft palate by Nicotiana glauca (wild tree tobacco) during the first trimester of pregnancy was compared between Spanish-type goats and crossbred western-type sheep. Cleft palate was induced in 100% of the embryonic/fetal goats when their pregnant mothers were gavaged with N. glauca plant material or with anabasine-rich extracts from the latter, during gestation days 32-41. Seventy-five percent of newborn goats had cleft palate after maternal dosing with N. glauca during gestation days 35-41, while no cleft palates were induced when dosing periods included days 36-40, 37-39, or day 38 only. The induced cleft palates were bilateral, involving the entire secondary palates with complete detachment of the vomer. Eleven percent of the newborn goats from does gavaged during gestation days 32-41 had extracranial abnormalities, most often contractures of the metacarpal joints. Most of these contractures resolved spontaneously by 4-6 weeks postpartum. One newborn kid also had an asymmetric skull due to apparent fetal positioning. No cleft palates were induced in lambs whose mothers were gavaged with N. glauca plant or anabasine-rich extracts during gestation days 34-41, 35-40, 35-41, 36-41, 35-51, or 37-50. Only one of five lambs born to three ewes gavaged with N. glauca plant material during gestation days 34-55 had a cleft palate, but all five of these lambs had moderate to severe contractures in the metacarpal joints. The slight to moderate contracture defects resolved spontaneously by 4-6 weeks postpartum, but the severe contractures resolved only partially. Embryonic/fetal death and resorption (determined by ultrasound) occurred in 25% of pregnant goats fed N. glauca compared to only 4% of pregnant sheep. Nicotiana glauca plant material contained the teratogenic alkaloid anabasine at 0.175% to 0.23%, dry weight, demonstrating that Spanish-type goats are susceptible to cleft palate induction by the natural toxin anabasine, while crossbred western-type sheep are resistant. However, clinical signs of toxicity were equally severe in goats and sheep, even though maternal alkaloid tolerance was generally lower in sheep. We postulate that an alkaloid-induced reduction in fetal movement during the period of normal palate closure is the cause of the cleft palate and multiple flexion contractures.

Abstract
The literature on Conium maculatum biochemistry and toxicology, dispersed in a large number of scientific publications, has been put together in this review. C. maculatum is a weed known almost worldwide by its toxicity to many domestic animals and to human beings. It is an Umbelliferae, characterized by long, hollow stems, reaching up to 2 m height at maturity, producing a large amount of lush foliage during its vegetative growth. Its flowers are white, grouped in umbels formed by numerous umbellules. It produces a large number of seeds that allow the plant to form thick stands in modified soils, sometimes encroaching on cultivated fields, to the extent of impeding the growth of any other vegetation inside the C. maculatum area of growth. Eight piperidinic alkaloids have been identified in this species. Two of them, gamma-coniceine and coniine are generally the most abundant and they account for most of the plant acute and chronic toxicity. These alkaloids are synthesized by the plant from eight acetate units from the metabolic pool, forming a polyketoacid which cyclises through an aminotransferase and forms gamma-coniceine as the parent alkaloid via reduction by a NADPH-dependent reductase. The acute toxicity is observed when animals ingest C. maculatum vegetative and flowering plants and seeds. In a short time the alkaloids produce a neuromuscular blockage conducive to death when the respiratory muscles are affected. The chronic toxicity affects only pregnant animals. When they are poisoned by C. maculatum during the fetuses organ formation period, the offspring is born with malformations, mainly palatoschisis and multiple congenital contractures (MCC; frequently described as arthrogryposis). Acute toxicity, if not lethal, may resolve in the spontaneous recovery of the affected animals provided further exposure to C. maculatum is avoided. It has been observed that poisoned animals tend to return to feed on this plant. Chronic toxicity is irreversible and although MCC can be surgically corrected in some cases, most of the malformed animals are lost. Since no specific antidote is available, prevention is the only way to deal with the production loses caused by this weed. Control with herbicides and grazing with less susceptible animals (such as sheep) have been suggested. C. maculatum alkaloids can be transferred to milk and to fowl muscle tissue through which the former can reach the human food chain. The losses produced by C. maculatum chronic toxicity may be largely underestimated, at least in some regions, because of the difficulty in associate malformations in offspring with the much earlier maternal poisoning.

Abstract
Any animal model of a human congenital anomaly established by iatrogenic methods involving intrauterine fetal manipulation has limited clinical applicability. A congenital model that more closely simulates the etiopathogenesis of a human anomaly may provide data that can more readily be extrapolated to that anomaly and, therefore, be used in diagnostic and management strategies. The present work provides a description and characterization of a congenital model of cleft palate in the goat. Palatal shelf closure normally occurs at approximately day 38 of gestation in the caprine species. Sixteen pregnant goats were gavaged twice daily during gestational days 32 through 41 [term, 145 days] with a plant slurry of Nicotiana glauca containing the piperidine alkaloid teratogen anabasine. Gross analysis and measurement of fetal clefts were performed at 60, 70, and 85 days gestation (four fetuses were studied at each time point). Seventeen clefted kids were sacrificed at specific intervals after birth (2 weeks, and 1, 3, and 6 months); after skull debridement and preparation, they were compared with 12 unclefted control kids. Complete clefting of the secondary palate occurred in 97 percent of the fetuses. In all cases, the cleft extended from the posterior aspect of the alveolar ridge to the uvula; the majority of these clefts were bilateral, with complete detachment of the vomer. Morphologically, these clefts were similar to human clefts. Eighteen percent of clefted newborn kids demonstrated gross maxillary hypoplasia and midfacial retrusion at birth with a relative Class III malocclusion. Direct measurement of the congenital caprine skulls confirmed these findings. The incidence of midfacial growth abnormalities in these clefted animals raises questions regarding the etiopathogenesis of facial dysmorphology that is unrelated to scarring of the maxilla. This congenital cleft palate model is currently being used to explore these questions and others related to craniofacial growth and palatal function after in utero repair.

Abstract
OBJECTIVE This study was undertaken to investigate a possible connection between different types of limb reduction defects and maternal smoking during pregnancy. METHODS With the use of the Swedish health registries, 610 cases of limb reduction malformations were selected from among 1 109 299 infants born between 1983 and 1993 with known smoking exposure in early pregnancy. Confounders such as maternal age and parity were controlled for with the use of the Mantel-Haenszel technique. RESULTS The odds ratio for any maternal smoking among all cases of limb reductions was 1.26 (95% confidence interval = 1.06, 1.50). The main subgroups of limb reduction defects showed similar odds ratios, but in longitudinal reduction defect, only unilateral cases showed an association with maternal smoking. CONCLUSIONS This study supports an association between maternal smoking and limb reduction malformations, but further work is needed before a causal inference can be made.

Abstract
Quinolizidine and piperidine alkaloid teratogens from Lupinus, Conium, and Nicotiana genera have been identified as causes of birth defects in livestock induced by poisonous plants. Many defects now known to be related to poisonous plant ingestion were once thought to have a genetic origin. This supposition delayed diagnosis, reporting, and understanding of such birth defects, because breeders and producers feared the news would make it difficult to sell breeding stock. Defects caused by quinolizidine and piperidine teratogens include cleft palate and contracture-type skeletal defects such as arthrogryposis, scoliosis, torticollis, and kyphosis. Teratogens have been identified, differences in susceptibility to teratogenic compounds among livestock species have been elucidated, periods of gestation when specific types of birth defects occur have been determined, and information about mechanism of action has been developed.

Abstract
This chapter provides evidence that alkaloids are not waste products or functionless molecules as formerly assumed, but rather defense compounds employed by plants for survival against herbivores and against microorganisms and competing plants. These molecules were developed during evolution through natural selection in that they fit many important molecular targets, often receptors, of cells, which are seen in molecules that mimic endogenous neurotransmitters. The chapter discusses that microorganisms and herbivores rely on plants as a food source. Since both have survived, there must be mechanisms of adaptations toward the defensive chemistry of plants. Many herbivores have evolved strategies to avoid the extremely toxic plants and prefer the less toxic ones. Many herbivores have potent mechanisms to detoxify xenobiotics, which allow the exploitation of at least the less toxic plants. In insects, many specialists evolved that are adapted to the defense chemicals of their host plant, in that they accumulate these compounds and exploit them for their own defense. Alkaloids function as defense molecules against insect predators in the examples studied, and this is further support for the hypothesis that the same compound also serves for chemical defense in the host plant. It needs more experimental data to understand fully the intricate interconnections between plants, their alkaloids, and herbivores, microorganisms, and other plants.

Abstract
Three piperidine alkaloid containing plants, Conium maculatum (poison-hemlock), Nicotiana glauca (tree tobacco) and Lupinus formosus (lunara lupine), induced multiple congenital contractures (MCC) and palatoschisis in goat kids when their dams were gavaged with the plant during gestation days 30-60. The skeletal abnormalities included fixed extension or flexure of the carpal, tarsal, and fetlock joints, scoliosis, lordosis, torticollis and rib cage abnormalities. Clinical signs of toxicity included those reported in sheep, cattle and pigs--ataxia, incoordination, muscular weakness, prostration and death. One quinolizidine alkaloid containing plant, Lupinus caudatus (tailcup lupine), on the other hand, which is also known to cause MCC in cows, caused only slight signs of toxicity in pregnant goats and no teratogenic effects in their offspring.

Abstract
Fetal movement, observed by ultrasound imaging, was significantly reduced (P less than or equal to 0.001) in pregnant goats gavaged with Conium seed and Nicotiana glauca and temporarily reduced with fresh Conium plant. Conium seed and Nicotiana glauca induced cleft palate and multiple congenital contractures in 100% of the kids born to pregnant goats gavaged with these plants. Multiple congenital contractures included torticollis, scoliosis, lordosis, arthrogryposis, rib cage anomalies, over extension, and flexure and rigidity of the joints. However, in goats gavaged with fresh Conium plant, fetal movement was inhibited for only about 5 hours after each individual dosage and gradually returned to control levels 12 hours after dosing. Fetal malformations in this group were limited from modest to moderate contractures of the front limbs, which resolved by 8-10 weeks post partum. No cleft palates were induced. Fetal movement was not inhibited in goats fed Lupinus caudatus and no cleft palates or multiple congenital contractures were induced in their offspring. The duration of the reduction in fetal movement appears to be an important factor in the severity and permanence of the deformities, particularly with cleft palate, spinal column defects, and severe joint deviation and fixation.

Abstract
A congenital deformity condition called crooked calf disease, of widespread occurrence in western North America, is known to be induced by maternal ingestion during gestation of certain members of the Lupinus genus containing the quinolizidine alkaloid teratogen anagyrine. Because some piperidine alkaloids from other sources induce a similar condition, we have investigated the alkaloid composition and teratogenicity of Lupinus formosus, reported by others to be low in quinolizidines but rich in the type of piperidine alkaloids that we have speculated would be teratogenic. GC/MS analysis of L. formosus showed seven major and nine minor components in the total alkaloid fraction. All seven major and five of the nine minor components, representing all but 3% of the fraction, were identified by mass spectrometric fragmentation patterns and GC retention times. They included several potentially teratogenic piperidine alkaloids (including a very large amount of ammodendrine), as well as several nonteratogenic quinolizidine alkaloids plus a trace (at nonteratogenic levels) of the known quinolizidine teratogen anagyrine. The plant induced severe crooked calf disease with limb, spinal, and palate involvement in experimental calves. The deformities are believed to have been induced by ammodendrine.

Abstract
Nicotiana glauca, wild tree tobacco, induces arthrogrypotic congenital defects in piglets similar to those induced by Nicotiana tabacum, common tobacco. The present work was conducted to isolate the principal alkaloid of N. glauca, anabasine, in large quantity and good purity and to test the teratogenicity of the compound in pigs. The isolated compound was established to be anabasine and to be of suitable purity by chemical characterization. It proved to be teratogenic. Typical arthrogrypotic defects were induced in 21 of 26 offspring (three of three litters) when dams ingested 2.6 mg of the compound per kg body weight twice daily during the 43rd-53rd days of gestation. Of three dams dosed with 1.66 g/kg/day of the dried plant material during the 43rd-53rd days, one delivered deformed offspring representing one-third of all offspring in that group. These arthrogrypotic defects induced by anabasine were indistinguishable clinically from defects induced by either N. glauca or N. tabacum. In addition, anabasine at a dose of 2.6 mg/kg twice daily or N. glauca plant material at 1.66 gm/kg daily induced cleft palate in over three-fourths of offspring (100% of litters) when dams ingested either during the 30th-37th days of gestation or during longer periods that included those days.

Abstract
Eighty-four of 147 piglets from 20 purebred Hampshire gilts that were bred to purebred Hampshire boars and then fed Nicotiana glauca during various periods of gestation were congenitally deformed. The deformities occurred in piglets from gilts on experiments in 3 separate years during which 4 different collections of the plant were fed. The deformities included various arthrogrypotic limb deviations and palate closure defects. Arthrogrypotic limbs had excessive flexure of pastern or carpal joints, medial rotation, or a combination of these effects. There were no gross visceral defects nor histopathologic changes in examined tissue. Expression of deformities varied as a function of gestation period. Palate closure defects, for example, occurred only in offspring from sows fed prior to gestation day 35. The limb deformities induced by N. glauca in piglets were similar to those reported by others and assumed, or known from feeding trials, to have been induced by maternal Nicotiana tabacum stalk ingestion. By contrast palate defects were not reported in piglets from maternal N. tabacum ingestion, but were of high incidence in the present work from maternal N. glauca ingestion. The suspect teratogen, anabasine, the principle piperidine alkaloid of N. glauca, varied in concentration among the collections fed. However dosages were maintained in each animal regardless of collection fed that resulted in daily toxicity signs indicative of anabasine toxicosis. The signs included depression, tremors, third eyelid closure, irregular gait and recumbency.

Abstract
An evaluation of over 350 patients in a study of congenital contractures of the joints (arthrogryposis) included a review of family, pregnancy, and delivery histories for teratogenic exposures. Fifteen out of the total 350 patients studied had a possible teratogenic exposure: an infectious agent (viral or bacterial), maternal drug or toxin ingestion, chronic maternal neurologic or muscular illness, or a direct physical insult such as a structural uterine anomaly. Literature was reviewed for all human and animal cases reported with congenital contractures of the joints with an associated teratogenic insult. Those findings are discussed here.

Abstract
This is a concept of multiple congenital contractures, based upon clinical experience with the malformation and available literature, leading to a conception of the multiple categories of etiology, which cause neuropathic or myopathic muscle weakness or limb immobilization. The muscle weakness and imbalance of muscle power around the joints elicits a physiological compensatory collagenic response, which replaces atrophied muscle fibers with connective tissue and thickens the joint capsule sufficiently to result in prenatal fixation of limb segments at the joint.
