We analyzed a set of variable-number tandem-repeat (VNTR) loci to assess their nucleotide sequence diversity in isolates of three Mycobacterium ulcerans genotypes. Sequence variants in two loci resulted in intraspecies resolution of Southeast Asian and Asian genotypes in contrast to a homogenous sequence composition among African isolates. Nucleotide sequence polymorphism in repeat units can en...

MicroRNAs have been implicated in many critical cellular processes including apoptosis. We have previously found that apoptosis in pancreatic cancer cells was induced by adamantyl retinoid-related (ARR) molecule 3-Cl-AHPC. Here we report that 3-Cl-AHPC-dependent apoptosis involves regulating a number of microRNAs including miR-150* and miR-630. 3-Cl-AHPC stimulated miR-150* expression and cause...

Seed dormancy is a genetically inherited trait whose intensity is modified by the environment during seed development and maturation. In order to study the effect of harvest time on the seed quality and optimum time of sowing to obtain good quality seeds, freshly threshed seeds of ten diverse rice genotypes harvested from six environments were evaluated for seed dormancy and seedling vigour ind...

in order to investigate the effects of water deficit at different growth stages of chickpea genotypes, determining the best drought tolerance index and genotypes, an experiment carried out in the saatlu agricultural research station of uromia in 2008-2009. the experiment was split plot based on the randomized complete blocks design with four replications, in which, four levels of irrigation as ...

in this study, we assessed the relative contribution of organic and inorganic solutes to osmotic adjustment (oa) in three almond rootstocks subjected to four levels of soil salinity. the results showed that leaf water and osmotic potentials were affected by salinity in gf677 and bitter almond, but less so in gn15, suggesting a higher selectivity for k+ and ca2+ against na+ in this latter rootst...

Soil salinity is one of the most important environmental factors threatening agriculture on a global level. Plants show differences in resistance to salt stress, both terms species and variety. The aim study was determine effect stress photosynthetic efficiency activity plants two barley varietie—KWS Irina RGT Planet. grown pot experiment were subjected soil treatment with sodium chloride (NaCl...
