4th Edition Of Plant Science and Molecular Biology World Conference 2027

Abiotic stress tolerance in plants is a major research priority as climate change increases heat, drought and salinity in farming regions, and this session at PMBWC 2027 examines the molecular mechanisms behind it. Heat, drought and salinity are among the main causes of yield loss in crops, and they often occur at the same time. Plants differ widely in how well they tolerate these conditions, and much of this variation is controlled at the molecular level. Climate change is expected to increase the frequency and intensity of heat waves, droughts and soil salinity in many farming regions. Plants respond to these stresses by changing gene expression, adjusting their metabolism and protecting their cells from damage. Identifying the genes and pathways involved provides valuable targets for breeding and biotechnology aimed at stable yields under difficult conditions.
 

This session covers stress sensing and signalling, hormone pathways such as abscisic acid, ion transport, osmotic adjustment and antioxidant systems. Studies on combined stresses and on the use of molecular findings to develop tolerant crop varieties are also included.
 

Key Topics Covered

• Heat stress responses and heat-shock proteins
