Abstract:
... The NBS-LRR genes are functionally responsible for plant resistance to alien pathogens. Here, we show that NBS-LRR genes originated in the common ancestor of the whole green lineage, and have rapidly diverged into three subclasses with different domain combinations (TNL, CNL, and RNL) before the split of green algae. ...

Abstract:
... Plants perceive a variety of molecules produced by microbes, insects, and nematodes. These pathogen-derived components include so-called microbe-associated molecular patterns, or MAMPs, as well as effector proteins that are secreted to the exterior or interior of plant cells and these molecules can be recognized by receptor protein complexes on the exterior or interior of plant cells, thereby acti ...

Abstract:
... Use of antimicrobial compounds traditionally for the treatment of bacterial infections has become a major concern nowadays, due to the emergence of resistance to conventional antimicrobials. The convergence of these drifts has led to the common incidence of extensively drug-resistant bacteria. This has led to fears of a “post-antibiotic era” in which many bacterial infections will be untreatable. ...

Abstract:
... Local interactions between individual plant organs and diverse microorganisms can lead to whole plant immunity via the mobilization of defense signals. One such signal is the plastid lipid-derived oxylipin azelaic acid (AZA). Arabidopsis lacking AZI1 or EARLI1, related lipid transfer family proteins, exhibit reduced AZA transport among leaves and cannot mount systemic immunity. AZA has been detect ...
