Polygalacturonase Isozymes and Pectin Depolymerization in Transgenic rin Tomato Fruit.

abstract：:Sulfur is vital for primary and secondary metabolism in plant roots. To understand the molecular and morphogenetic changes associated with loss of this key macronutrient, we grew Arabidopsis (Arabidopsis thaliana) seedlings in low-sulfur conditions. These conditions induced a cascade of cellular events that converged ...
