The domestic water buffalo (Bubalus bubalis) are classified into the swamp and riverine. However, their hybrids are also found in some parts of Assam (Brahmaputra Valley) in North-east India. Swamp buffaloes have a typical phenotypic appearance, like the shape of horns, small size, and body-color, etc. This study characterizes the indigenous ‘Bhangor’ buffalo population from the Tripura state using cytogenetic analyses. The blood of buffaloes samples were collected across the state, phenotypically identified as swamp buffaloes were cultured, terminated, and harvested using conventional karyotype protocol to determine the number of chromosomes. We have characterized ‘Bhangor’ an indigenous buffalo population from Tripura state using karyotypic analysis for the first time to confirm that all animals phenotypically identified as swamp buffaloes with 2N=48 chromosomes.

The Asiatic wild buffalo Bubalus bubalis was widely distributed in the river systems of south and South East Asia, but habitat destruction, hunting and interbreeding with domestic water buffalo have resulted in only relict wild populations remaining. Unless protection measures are intensified, the species could disappear in India within a few decades.

Background: Duck farming plays a significant role, next to chicken in the socio-economic uplift men of the rural farmers of North-East India. Pati duck is the most common duck breed in the Brahmaputra valley of Assam and the other common variety reared in North-East India is Chara-Chambeli, however it originatein Kerala. Genetic characterization plays a significant role for formulation of breeding strategies for improvement of any breed. Microsatellites are codominant in nature and are highly polymorphic. High level of allelic variation, co-dominant mode of inheritance and potential for automated analysis make them an excellent tool for genotyping, mapping and genetic characterization. Pati duck is the most common duck breed in the Brahmaputra valley of Assam and the other common variety reared in North-East India is Chara-Chambeli however its origin in Kerela. Therefore, the present investigation was carried out to characterize these two duck breeds using microsatellite markers to evaluate the genetic diversity in these two duck population. Methods: For the present study, Blood sample were collected from 50 Patiducks and 50 Chara-Chambeli ducks from different parts of North-East India. Assessment of genetic characterization of duck breeds of north-east region were carried out using 16 microsatellite markers and population genetics analysis were done by POPGENE software. Result: In the present study, all the studied loci were highly polymorphic. Analysis generated a total of 41 microsatellite alleles. The number of observed alleles (Na) with an overall mean of 1.93±0.258. However, the effective number of alleles (Ne) with a mean of 1.6933±0.2712. The Shannon’s information index was found to a mean value of 0.5685±0.1693. The overall means for observed (HO) and expected (He) heterozygosities were 0.2889±0.2477 and 0.5289±0.0853, respectively. The chi-square (χ2) test for Hardy-Weinberg equilibrium revealed that all the loci are in within Hardy-Weinberg equilibrium.

Gnetum gnemon L. (Gnetaceae) is used traditionally for treating malaria related fever by indigenous people of North East India. In our preliminary study, the ethanol extract of G. gnemon leaves showed promising antiplamodial activity against Plasmodium falciparum chloroquine sensitive (3D7) strain in vitro with an IC50 value of 29.4 μg/mL. Therefore, it was further investigated, and by following a bioassay guided approach, 2,3-dihydroxypropyl icosanoate (1), oleic acid (2) and ursolic acid (3) were isolated for the first time from this plant. Compound 3 showed highest antiplasmodial activity with IC50 values of 4.0 and 6.0 μg/mL against chloroquine sensitive (3D7) and resistant (Dd2) strains of P. falciparum, respectively. The antiplasmodial activity of 1 (IC50 9.5 and 11.4 μg/mL) and 2 (IC50 17.6 and 21.1 μg/mL) was moderate. The isolated constituents showed low cytotoxicity against rat skeletal muscle (L6) and human cervical cancer (HeLa) cells. This is the first report on the antimalarial potential of G. gnemon and the isolated compounds may be responsible for its activity. The findings of the study are in line with the ethnopharmacological claim and can be possible leads for future studies.

Chromosomal study conducted in nine species of Dioscorea from different forest belts of Tripura revealed that their somatic chromosome number ranged from 2n=40 to 2n=60. The record of 2n=40 chromosome in the sexual phenotypes of Dioscorea hamiltonii, Dioscorea glabra and Dioscorea pubera are the first time report from Tripura, North East India. Moreover the somatic chromosome counts of 2n=60 in Dioscorea pentaphylla would be attributed as a new cytotype. However at the respective ploidy level no difference in somatic chromosome count was observed between their sexes.

Brahmaputra Valley

North east India is one of the exotic hotspots for Asian elephant (Elephas maximus) and harbors about half of the global population of the Asian elephant. Here we present the first population genetic study of free-ranging Asian elephants, examining within- and among-population differentiation by analyzing mitochondrial DNA (mtDNA) differentiation across the Brahmaputra valley and elephant reserves of North east India. Surprisingly, the population here had shown lower mtDNA haplotype diversity with little mtDNA differentiation among localities within the Brahmaputra valley. This suggests extensive gene flow in the past, which is compatible with the home ranges of several hundred square kilometers for elephants in this region. Conversely, the Brahmaputra valley population is genetically distinct at a mitochondrial level than other tested elephant populations. These results significantly indicate the importance of population bottlenecks, social organization, and bio-geographic barriers in shaping the distribution of genetic variations among Asian elephant populations in North east India.
