The role of sucrose in phosphate starvation response: transcriptomic and physiological insights in Arabidopsis Thaliana.

ABSTRACT:

Background

Pi (inorganic phosphate) is an essential mineral nutrient and a key limiting factor for plant growth. Environmental factors of carbon and energy status provided by sucrose influence plant growth and stress adaption; however, the mechanisms by which plant seedlings cope with Pi-starvation stress in conjunction with these factors remain largely unknown.

Results

This study investigates the interplay between sucrose status and Pi-starvation response using a combined Pi/sucrose treatment. Through comparative transcriptomic and physiological analyses, we demonstrated that: (1) the upregulation of anthocyanin biosynthesis under Pi-starvation is significantly attenuated under sucrose deficiency, coinciding with reduced anthocyanin and ROS (reactive oxygen species) accumul
