Melatonin-mediated regulation of autophagy is independent of ABA under drought stress in sensitive variety of Gossypium hirsutum L.

Autophagy is a highly conserved process that plays a crucial role in adaptation of plants to stress conditions. Melatonin and abscisic acid (ABA) share an antagonistic relationship; however, both are reported to elevate autophagy individually. Here, we report that melatonin alleviates drought stress effects like wilting and stunted growth in 18-day-old plants of drought-sensitive variety of cotton (Gossypium hirsutum L.

Pyramiding of qDTY and qDTY into rice mega-variety Samba Mahsuri-Sub1: physiological performance under water deficit conditions.

Unlabelled: Water deficit is a crucial factor causing huge loss to rice productivity. The present study aimed to develop a multiple stress tolerant genotype by pyramiding drought tolerant yield QTLs qDTY and qDTY into high yielding rice variety Samba Mahsuri Sub-1(SMS) through marker assisted pyramiding. To achieve this six introgression lines of SMS carrying qDTY (SAB) were crossed with DRR-50, an Essentially Derived Variety of SMS carrying qDTY.
