Abstract
Genetically diverse cottonseeds show altered compositions and spatial distributions of phosphatidylcholines and triacylglycerols. Lipidomics profiling led to the discovery of a novel FAD2 - 1 allele, fad2 - 1D - 1 , resulting in a high oleic phenotype. The domestication and breeding of cotton for elite, high-fiber cultivars have led to reduced variation of seed constituents within currently cultivated upland cotton genotypes. However, a recent screen of the genetically diverse U.S. National Cotton Germplasm Collection identified Gossypium accessions with marked differences in seed oil and protein content. Here, several of these accessions representing substantial variation in seed oil content were analyzed for quantitative and spatial differences in lipid compositions by mass spectrometric approaches. Results indicate considerable variation in amount and spatial distribution of pathway metabolites for triacylglycerol biosynthesis in embryos across Gossypium accessions, suggesting that this variation might be exploited by breeders for seed composition traits. By way of example, these lipid metabolite differences led to the identification of a mutant allele of the D-subgenome homolog of the delta-12 desaturase (fad2-1D-1) in a wild accession of G. barbadense that has a high oil and high oleic seed phenotype. This mutation is a 90-bp insertion in the 3' end of the FAD2-1D coding sequence and a modification of the 3' end of the gene beyond the coding sequence leading to the introduction of a premature stop codon. Given the large amounts of cottonseed produced around the world that is currently not processed into higher value products, these efforts might be one avenue to raise the overall value of the cotton crop for producers.

Abstract
A global analysis of cotton (Gossypium spp.) genetic diversity is the first step to understanding its geographical distribution, dissemination, genetic relatedness, and population structure. To assess the genetic diversity and population structure in Gossypium species, 111 cotton accessions representing five allotetraploids (AD1–AD5 genomes), 23 Asiatic diploids of the Old World (A1 and A2 genomes), and 82 diploids of the New World subgenus Houzingenia (D1–D11 genomes) species were assessed using simple sequence repeats (SSR) markers with wide genome coverage. The mean genetic distance (GD) between the two most important New World tetraploid cottons (Upland (Gossypium hirsutum L.) and Pima (Gossypium barbadense L.)) was 0.39. Among the three shrub type sections (Houzingenia, Integrifolia, and Caducibracteolata) and three arborescent sections (Erioxylum, Selera, and Austroamericana), the GD ranged between 0.19 and 0.41. Phylogenetic analyses clustered all species into distinct phylogenetic groups, which were consistent with genomic origin, evolutionary history, and geographic distribution or ecotypes of these accessions, suggesting the existence of clear structured strata. With all of the genomes, the highest statistical analysis of Structure test through measurements of ad hoc (ΔK) occurred at K = 2, with group Q1 with the Old World diploid A genomes and with group Q2 with all the New World diploids of the D genome. AD genome accessions shared nearly equal alleles from both Q1 and Q2 groups. With all of the diploids of the New World D genomes, the highest value of ΔK occurred at K = 5. These results are consistent with the fundamental knowledge of tetraploid AD-genome formation and the rapid radiation of the American diploid cotton linage that took place somewhere in southwestern Mexico, followed by a differentiation–speciation during angiosperm evolution. In addition, SSR markers provide an alternative solution for distinguishing phylogenetic relationships between accessions of different ecotypes and for elucidating population structure of cottons of the New World.

Abstract
In Uganda, control of vector-borne diseases is mainly in form of vector control, and chemotherapy. There have been reports that acaricides are being misused in the pastoralist systems in Uganda. This is because of the belief by scientists that intensive application of acaricide is uneconomical and unsustainable particularly in the indigenous cattle. The objective of this study was to investigate the strategies, rationale and effectiveness of vector-borne disease control by pastoralists. To systematically carry out these investigations, a combination of qualitative and quantitative research methods was used, in both the collection and the analysis of data. Cattle keepers were found to control tick-borne diseases (TBDs) mainly through spraying, in contrast with the control of trypanosomosis for which the main method of control was by chemotherapy. The majority of herders applied acaricides weekly and used an acaricide of lower strength than recommended by the manufacturers. They used very little acaricide wash, and spraying was preferred to dipping. Furthermore, pastoralists either treated sick animals themselves or did nothing at all, rather than using veterinary personnel. Oxytetracycline (OTC) was the drug commonly used in the treatment of TBDs. Nevertheless, although pastoralists may not have been following recommended practices in their control of ticks and tick-borne diseases, they were neither wasteful nor uneconomical and their methods appeared to be effective. Trypanosomosis was not a problem either in Sembabule or Mbarara district. Those who used trypanocides were found to use more drugs than were necessary.

Abstract
The structure and fine structure of the pituitary gland in the sea lamprey, Petromyzon marinus L., are described at all major stages in the life cycle. Synthetically active adenohypophysial cells are evident in even the smallest ammocoetes examined (body length 2.5 cm). An attempt is made to correlate changes in the activity of pituitary cell types with biological events. In the neurohypophysis a single fibre type was discriminated in electron micrographs. This contained electron-dense cytoplasmic granules 800 to 1600 A in diameter.
