soil affected by salt (nacl) is a major problem worldwide and in areas with potential agriculture; lands in many countries are not enough to support crop production. the development of salt tolerant cultivars would be enhanced by better understanding of the genetic control of tolerance to salt stress. a new cereal, tritipyrum, a range of amphiploids between triticum spp. and thinopyrum spp....

Cereal grains rich in starch are widely used to meet the energy demands of high-producing beef and dairy cattle. Bacteria are important players in starch digestion in the rumen, and thus play an important role in the hydrolysis and fermentation of cereal grains. However, our understanding of the composition of the rumen starch-hydrolyzing bacteria (SHB) is limited. In this study, BODIPY FL DQ s...

Preimplantation genetic diagnosis (PGD) is well established method for treatment of genetic problems associated with infertility. Moreover, PGD with next-generation sequencing (NGS) provide new possibilities for diagnosis and new parameters for evaluation in, for example, aneuploidy screening. The aim of the study was to report the successful pregnancy outcome following PGD with NGS as the meth...

By employing the technique of induced ovulation for artificial fertilization, inter-specific hybrids between the threatened catfish species (Mystus cavasius x M. seenghala) were produced. Fertilization, hatching and survival were significantly different between control and hybrids. The hatching time of the hybrid was significantly lower than that of the control. The average performance viz., ha...

The ability of 223 Type II restriction endonucleases to hydrolyze RNA-DNA heteroduplex oligonucleotide substrates was assessed. Despite the significant topological and sequence asymmetry introduced when one strand of a DNA duplex is substituted by RNA we find that six restriction enzymes (AvaII, AvrII, BanI, HaeIII, HinfI and TaqI), exclusively of the Type IIP class that recognize palindromic o...
