Drought stress intensifies early blight and compromises potato yield.

Pest management science | 2026-Apr-14

This study evaluates the interaction between drought stress and early blight (Alternaria alternata) susceptibility across 44 potato genotypes. The research identifies specific resistant and susceptible genotypes, demonstrating that water stress significantly increases disease severity and reduces yield, providing valuable data for breeding programs focused on multi-stress resilience.

Morphological and hormonal diversity in rose (Rosa hybrida L.) and potato (Solanum tuberosum L.) Ri genotypes: A comparative study.

PloS one | 2026

This study investigates the morphological and hormonal changes in potato (Solanum tuberosum) Ri genotypes created via Rhizobium rhizogenes-mediated transformation. By analyzing T-DNA gene expression and hormone profiles, the research identifies genetic mechanisms underlying altered plant architecture and root development, offering potential applications for potato breeding.
