Over the recent years, results from investigation into the family Horseshoe bats (Rhinolophidae) indicated that the taxonomic status of many species in Vietnam is still unclear. Having studied on 1,140 specimens of the genus Rhinolophus, we confirm that Vietnam is a home to 20 horseshoe bat species. Remarkably, our study results obtained 6 unusu...

SUMMARY Soybean is a drought-sensitive crop, thus their productivity is significantly affected by this factor. Among two soybean varieties studied, based on the evaluation of root and shoot growth and architecture under drought treatment and normal condition, our results showed that MTD777-2 is more drought-resistant than the control Williams 8...

According to the CAZY classification, endo 1- 4 xylanase belongs to GH 5, 8, 10, 11, 30, 51, 98. However only 03 sequences of GH8, 27 sequences of GH10, 18 sequence of GH11, only one sequence of each GH30 and GH51 from CAZy and NCBI database were thouroughly experimentally studied for biological activity and characteristics of the enzyme. Throug...
