The cucumber (Cucumis sativus L.) is one of the most important vegetables in Bangladesh as well as across the globe. However, many of the important cucumber landraces have disappeared in Bangladesh due to climate change, particularly erratic rainfall, extreme temperature, salinity, and drought. Therefore, to protect against the extinction of the cu...

Drought is the most severe abiotic stress affecting about 50% of the world's rice production. Rice breeding under drought is challenging due to lack of standardized screening protocols and poor understanding of genetics. The drought‐breeding program at the International Rice Research Institute (IRRI) has successfully established a standardized scre...

D-ononitol epimerase (OEP) catalyzes the conversion of D-ononitol to D-pinitol, which is the last step in the biosynthetic pathway, where myo-inositol is converted to pinitol in higher plants. In this study, OEP cDNA was isolated from Glycine max (GmOEP) and was functionally characterized, which confirmed that GmOEP expression was induced by high s...
