The plant apoplast during plant-pathogen interactions is an ancient battleground that holds an intriguing range of attacking enzymes and counteracting inhibitors. Examples are pathogen xylanases and polygalacturonases that are inhibited by plant proteins like TAXI, XIP, and PGIP; and plant glucanases and proteases, which are targeted by pathogen proteins such as GIP1, EPI1, EPIC2B, and AVR2.

ABSTRACT: Crop residues decomposition are controlled by chemical tissue components. This study evaluated changes on plant components, separated the Van Soest partitioning method, during cover crop decomposition. The soluble fraction was first to be released from residues, followed cellulose and hemicellulose. Lignin residue component that suffered least degradation, for certain types, lignin de...

Wheat (Triticum aestivum) growth and yield are depressed by physical and chemical interference of weeds. Recently, wild barley (Hordeum spontaneum) population has increased in wheat fields of many provinces of Iran. Since, little is known about the allelopathic effects of wild barley residues in soil, greenhouse studies were conducted to examine the effects of soil amended residues of wild barl...
