RESUMO
Antioxidant properties, physico-chemical characteristics and proximate composition of five wild fruits viz., Garcinia pedunculata, Garcinia xanthochymus, Docynia indica, Rhus semialata and Averrhoa carambola grown in Manipur, India were presented in the current study. The order of the antioxidant activity and reducing power of the fruit samples was found as R. semialata > D. indica > G. xanthochymus > A. carambola > G. pedunculata. Good correlation coefficient (R(2) > 0.99) was found among the three methods applied to determine antioxidant activity. Total phenolic content was positively correlated (R(2) = 0.960) with the antioxidant activity however, total flavonoid content was not positively correlated with the antioxidant activity. Physico-chemical and proximate composition of these fruits is documented for the first time.
RESUMO
Different protocols are usually used for extracting total deoxyribonucleic acid (DNA) from different plant species of same order and DNA of the associated viruses. Here, we describe a rapid, efficient and universal protocol for isolating total DNA from the members of Zingiberales which harbor a high amount of polysaccharides and secondary metabolites. DNA isolated with this protocol was successfully used for PCR based downstream applications viz. random amplified polymorphic DNA (RAPD), Inter-simple sequence repeats (ISSR), DNA barcoding gene (Internal transcribed spacer and trnl-f) amplification and detection of the viruses.
RESUMO
UNLABELLED: : Being poor man's apple, banana has a wide popularity worldwide. It's one of the important horticultural crops used irrespective of rich and poor alike. Manipur along with the other states of Northeast India harboured with plenty of wild and cultivated species of banana that are not fully explored. A data base named DEBDOM has been developed here describing the diversity of banana resources of Manipur and it comprises twenty eight genotypes of Musaceae. The database DEBDOM provides a sophisticated web base access to the details of the taxonomy, morphological characteristics, utility as well as sites of collection of Musa genotypes, and it would have contribute as a potential gene pool sources for the conservation, sustainability as well as for crop improvement in the future breeding programmes.

RESUMO
UNLABELLED: The rich wealth of Citrus genetic resources makes India to enjoy a remarkable position in the "Citrus belt of the world". We have developed CIBMAN, a unique database on Citrus biodiversity of Manipur which comprises 33 accessions collected through extensive survey for more than three years. CIBMAN provides integrated access to Citrus species through sophisticated web interface which has following capabilities a) morphological details, b) socio-economic details, c) taxonomic details and d) geographical distribution. Morphological variability among Citrus accessions is due to variance in their genome which contributes to diverse agronomical traits and diverse bioactive compounds of high value. This diverse gene pool can be potential source for genetic improvement of existing cultivars and rootstocks. Systematic collection, characterization and conservation of the underutilized or lesser exploited varieties is required for incorporating in breeding program and conserve the germplasm from ever going on genetic erosion. This database will be useful for scientific validations and updating of traditional wisdom in bioprospecting aspects especially industrialization of Citrus found in the state. Further, the features will be suited for detailed investigation on potential medicinal and edible Citrus that make CIBMAN a powerful tool for sustainable management.
