Quantitative trait loci (QTL) mapping for intermittent drought tolerance in BRB 191 × SEQ 1027 Andean Intra-gene cross recombinant inbred line population of common bean (Phaseolus vulgaris L.).

Drought is a major constraint of common bean (Phaseolus vulgaris L.) production in Uganda where irrigation for the crop is very uncommon. This study aimed to identify quantitative trait loci (QTLs) underlying drought tolerance in 128 F5 RILs derived from an Andean intra-gene cross between drought-tolerant SEQ 1027 and BRB 191. Eighteen traits were evaluated under drought stress and non-stress conditions in the field for...

Flavonoids in neuropathic pain management: A new player on an old target

Neuropathic pain is the consequence of abnormal processing in the peripheral or central nervous system (CNS) elicited by neuronal injury. Due to its heterogeneous nature and important unwanted adverse effects of the commonly prescribed psychoactive drugs like benzodiazepines (BDZ), the treatment of neuropathic pain has remained a challenge for the scientific community. Flavonoids initially isolated from plants and used...
