TL;DR: The structure, chemistry of gelation, interactions, and industrial applications soft pectin are described.

TL;DR: Investigation of cultured tobacco cells adapted to grow under osmotic stress revealed that osmotin is concentrated in dense inclusion bodies within the vacuole, and although antiosmotin did not label organelles, cell walls, or membranes, osmotins appeared sparsely distributed in the cytoplasm.

TL;DR: Results provide the first direct evidence for a physiological role of polyamines and demonstrate an approach to improving nutritional quality, juice quality, and vine life of tomato fruit.

TL;DR: A cell wall‐associated protein that specifically binds the viral MP was purified from tobacco leaf cell walls and identified as pectin methylesterase (PME), and deletion of the PME‐binding region resulted in inactivation of TMV cell‐to‐cell movement.

TL;DR: This work generated loss-of-function mutant alleles of a tomato gene, SlDML2, which is a close homolog of the Arabidopsis DNA demethylase gene ROS1, and discovered that SlD ML2 is required for the demethylation and activation of genes important for fruit ripening, including genes involved in fruit pigment and flavor synthesis, ethylene synthesis and signaling, and cell wall hydrolysis.
