Abstract
Turmeric, a globally cultivated spice, holds significance in medicine, and cosmetics, and is also a very popular ingredient in South Asian cuisine. A study involving 53 turmeric genotypes evaluated for rhizome yield and related traits at Spices Research Center, Bogura, Bangladesh over three years (2019-22). A randomized complete block design was followed with two replications. ANOVA revealed significant trait variations among genotypes. Genotype T0015 emerged as the highest yielder at 28.04 t/ha. High heritability (0.58-0.99) and genetic advance characterized plant height (PH), mother rhizome weight (WMR), primary and secondary finger weights (WPF and WSF), and yield per plant (YPP) across seasons. Genetic gain (GG) was prominent in these traits. Genotypic and phenotypic coefficient variations (GCV and PCV) (6.24-89.46 and 8.18-90.88, respectively) across three years highlighted mother rhizome weight's importance followed by numbers of primary finger (NPF), and WPF. Positive and significant correlations, especially with PH, WMR, WPF, and YPP, emphasized their relevance to fresh yield (FY). Multiple linear regression identified PH, number of mother rhizome (NMR) and WMR as key contributors, explaining 37-79% of FY variability. Cluster analysis grouped genotypes into five clusters with maximum distance observed between clusters II and III. The geometric adaptability index (GAI) assessed adaptability and superiority, revealing nine genotypes outperforming the best existing cultivar. Genotype T0117 as the top performer based on GAI, followed by T0103 and T0094. Mean rank analysis favoured T0121 as the best performer, succeeded by T0117, T0082 and T0106. The top ten genotypes (T0015, T0061, T0082, T0085, T0094, T0103, T0106, T0117, T0121 and T0129) were identified as superior based on yield and overall ranking, warranting further evaluation. These findings may induce a window for improving turmeric research and ultimately play a role in enhancing its cultivation and productivity.

Molecular genetic divergence analysis amongst high curcumin lines of Golden Crop (Curcuma longa L.) using SSR marker and use in trait-specific breeding. Sci Rep 2023; 13:19690. [PMID: 37952010 PMCID: PMC10640617 DOI: 10.1038/s41598-023-46779-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Accepted: 11/04/2023] [Indexed: 11/14/2023] Open
Abstract
Curcuma longa L., is recognized worldwide as a medicinally and economically important plant species due to its curcumin content which is an industrially important compound. In this study, a total of 329 accessions were collected from four states of India and planted in the experimental farm of CSIR-NEIST, Jorhat, India, in augmented design. Among these, 152 high curcumin (> 1.50%) accessions were screened for molecular divergence study using 39 SSR primers. The primers showed the most efficient outcome with 2-8 allele/ loci and a total 163 number of alleles with 100% polymorphism. Cluster analysis revealed the construction of three clusters, out of which one cluster was geographically dependent, and germplasm was particularly from Assam state. Jaccard's pairwise coefficient showed maximum genetic dissimilarity of (0.75) between accession RRLJCL 3 and RRLJCL 126, indicating high variation as it was from two different states viz Arunachal Pradesh and Nagaland respectively and minimum genetic dissimilarity of (0.09) between RRLJCL 58 and RRLJCL 59 indicating significantly less variation as the two accessions were from same state, i.e., Arunachal Pradesh. Analysis of Molecular Variance (AMOVA) revealed high molecular variation within the population (87%) and significantly less variation among the population (13%). Additionally, Neighbour Joining dendrogram, Principal Component Analysis (PCA), and bar plot structure revealed similar clustering of germplasm. This diversity assessment will help in selecting the trait-specific genotypes, crop improvement program, conservation of gene pool, marker-assisted breeding, and quantitative trait loci identification. Moreover, to the best of our knowledge, it is the first molecular diversity report among 152 high curcumin lines of C. longa from North East India using 39 SSR primers.

Br. ex Schult. populations using DAMD and ISSR markers. J Genet Eng Biotechnol 2023; 21:42. [PMID: 37022506 PMCID: PMC10079795 DOI: 10.1186/s43141-023-00497-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 03/20/2023] [Indexed: 04/07/2023]
Abstract
BACKGROUND Gymnema sylvestre (Retz.) R. Br. ex Schult. is a well-known medicinal plant against diabetes in India. There is as such no organized cultivation in India, and the plant is still being collected from the wild for their therapeutic uses. It is, therefore, important to estimate the genetic diversity and population genetic structure of G. sylvestre to ascertain the genetically diverse germplasm. The present study, therefore, was undertaken to analyze the genetic variability in 118 accessions belonging to 11 wild populations of G. sylvestre using directed amplification of minisatellite-region DNA (DAMD) and inter simple sequence repeats (ISSR). RESULTS The present genetic analyses of 11 populations with 25 markers (8 DAMD and 17 ISSR) revealed significant genetic diversity (H = 0.26, I = 0.40, PPL = 80.89%) at a species level, while the average genetic diversity at the population level was low. Among the 11 populations studied, PCH and UTK populations showed maximum genetic diversity, followed by KNR and AMB, while TEL population revealed the lowest genetic diversity. AMOVA and Gst values (0.18) revealed that most of the genetic variations are found within populations and very less among populations, and higher gene flow (Nm = 2.29) was found to be responsible for the genetic homogenization of the populations. The clustering pattern resulting from the UPGMA dendrogram was in congruence with STRUCTURE and PCoA, segregating all the 11 populations into two main genetic clusters: cluster I (populations of North and Central India) and cluster II (populations of South India). The clustering patterns obtained from all three statistical methods indicate that the genetic structure in G. sylvestre populations corresponds to the geographical diversity of the populations and represents a strong genetic structure. CONCLUSION The genetically diverse populations identified during the present study could be a potential genetic resource for further prospecting and conserving this important plant resource.

Abstract
Background Mancozeb-a widely used fungicide in the agricultural sector-is believed to cause toxicity by increasing oxidative stress. This work investigated the efficacy of curcumin in protecting mancozeb-induced hepatotoxicity. Materials and Methods Mature Wistar rats were assigned into 4 equal groups: control, mancozeb (30 mg/kg/day, ip), curcumin (100 mg/kg/day, po), and mancozeb+curcumin. The experiment lasted for 10 days. Results Our results reported that mancozeb elevated aspartate transaminase, alanine transaminase, alkaline phosphatase, lactate dehydrogenase, gamma glutamyltranspeptidase enzyme activities, and total bilirubin level in plasma; and decreased total protein and albumin levels, compared with the control group (P < 0.05-0.001). Hepatic tissue levels of malondialdehyde, and advanced oxidation protein products were significantly increased; whereas activities of superoxide dismutase, catalase, glutathione peroxidase, as well as levels of reduced glutathione, vitamin C, and total protein were reduced (P < 0.05-0.001). Histopathological examination showed marked histological changes. Co-treatment with curcumin improved the antioxidant activity; reversed oxidative stress and biochemical changes; and restored most of the liver histo-morphological alterations; thus, attenuating the hepatic toxicities induced by mancozeb. Conclusion These results indicated that curcumin could protect against detrimental hepatic effects induced by mancozeb.

Abstract
OBJECTIVE The purpose of this study was to assess the effectiveness of yellow turmeric-infusa of 5% and 10% on the healing process of perineal wound grade II. METHOD The method used in this study is quasi-experiment with Pretest-Posttest Control Group design. The sampling technique is Exhaustive Sampling according to inclusion criteria. In this research consisted of three experimental groups with two intervention groups and one control group, with the number of subjects group was 15 people. Turmeric infusa is used daily by washing in the perineal wound area two times a day for 5 days postpartum. Monitoring of grade II perineal wound was performed three times, days 1, 5, and 7 postpartum using REEDA scale assessment. Data analysis used Kruskal-Wallis and Chi-Square tests. RESULTS The results showed that on the 5th and 7th postpartum days, there were differences in redness, edema, and approximation of wounds in each group (p<0.05) while the other REEDA parameters were not significantly different. There is also a difference in the time of perineal wound healing in each group, and it can be seen from the decrease and the total REEDA score. Turmeric infusa group 5% experienced healing on the 5th day postpartum, turmeric infusa 10% recovered on the 7th day postpartum, and the control group recovered more than 7 days. CONCLUSION Giving turmeric was proven to eliminate redness, edema, accelerate the closure, and perineal wound healing time, as seen from the p-value (p<0.05). However, turmeric infusa of 5% and 10% showed better effectiveness than turmeric infusa of 5%.

Abstract
Aluminum (Al) among the abundant metals on the earth crust, is able to cross the biological barriers via the gastrointestinal and lung tissues. Once in the body, this heavy metal accumulates in different organs, especially the central nervous system. Though its influence is evidently shown in the substantia nigra of Parkinson's disease patients and other brain areas in other neurodegenerative diseases, few studies have demonstrated that Al could trigger profound changes in neurotransmission systems including the dopaminergic (DAergic) system. A variety of medicinal plants may be prescribed in such contamination, including some culinary spices such as Curcumin (Cur). Several studies have proven Cur to exhibit a wide variety of biological and pharmacological activities, especially its antioxidant potential. Using the immunohistochemistry, of tyrosine hydroxylase (TH), in the midbrain substantia nigra pars compact (SNc) and the ventral tegmental area (VTA) and the open field test, we examined the DAergic system together with the locomotor behavior respectively in rats exposed chronically to Al (0,3%) in drinking water during 4 months since the intra-uterine age, as well as the neuroprotective effect of the concomitant administration of Cur I (30 mg/kg B.W) of chronic Al exposed rats. Our results have shown a significant decrease of TH immureactivity in both SNc and VTA associated to a loss of the number of crossed boxes, leading to a difficient locomotor performance in the Al group while Cur I prevents such TH immunoreactivity impairment and maintains a higher locomotor activity in the Al-CurI group. Our findings lead to suppose a powerful and obvious neuroprotective potential of CurI against Al-induced neurotoxicity of the DAergic system involved in the control of the locomotor behavior.

Abstract
Costus pictus, belonging to the family Costaceae, is one of the valuable medicinal plants with its anti-diabetic property. Despite ever-increasing demand from the pharmaceutical industry, this species is being less exploited at molecular level. Hence, an effort has been made in the present study to characterize the 15 accessions of C. pictus collected from different geographical regions of India through random amplified polymorphic DNA (RAPD) and inter-simple sequence repeats (ISSR) markers. A total of 25 RAPD and 20 ISSR primers were used in the present study. The RAPD analysis generated 343 loci, of which 124 were polymorphic with an average of 4.96 loci per primer. While, ISSR primers produced 177 loci, of which 77 were polymorphic with an average of 3.85 loci per primer. The similarity coefficients ranged from 0.86-0.99, 0.84-0.95 and 0.86-0.96 for RAPD, ISSR and combined RAPD-ISSR, respectively. The UPGMA dendrogram generated using these data showed low level of divergence among the accessions from South and West regions. Further, accession-specific bands were also revealed by RAPD and ISSR markers which might be contributed to specific trait. This investigation was an understanding of genetic variation within the C. pictus accessions. The present finding indicates that both the marker tools RAPD and ISSR combined or individually can be used in determining the genetic relationship between the accessions. It may be concluded that data of hereditary differences appeared among the C. pictus accessions could be utilized for their conservation and reproducing programs.

Abstract
Turmeric (Curcuma longa L., family Zingiberaceae) is one of the most economically important plants for its use in food, medicine, and cosmetic industries. Cultivar identification is a major constraint in turmeric, owing to high degree of morphological similarity that in turn, affects its commercialization. The present study addresses this constraint, using EST-SSR marker based, molecular identification of 8 elite cultivars and 88 accessions in turmeric. Fifty EST-SSR primers were screened against eight cultivars of turmeric (Suroma, Roma, Lakadong, Megha, Alleppey Supreme, Kedaram, Pratibha, and Suvarna); out of which 11 primers showed polymorphic banding pattern. The polymorphic information content (PIC) of these primers ranged from 0.13 to 0.48. However, only three SSR loci (CSSR 14, CSSR 15, and CSSR 18) gave reproducible unique banding pattern clearly distinguishing the cultivars 'Lakadong' and 'Suvarna' from other cultivars tested. These three unique SSR markers also proved to be effective in identification of 'Lakadong' cultivars when analysed with 88 accessions of turmeric collected from different agro-climatic regions. Furthermore, two identified cultivars (Lakadong and Suvarna) could also be precisely differentiated when analysed and based on phylogenetic tree, with other 94 genotypes of turmeric. The novel SSR markers can be used for identification and authentication of two commercially important turmeric cultivars 'Lakadong' and 'Suvarna'.
