Abstract:
... Plants are the ultimate producers of this ecosystem and effect human life directly and/or indirectly. However, being sessile organisms, plants are susceptible to several adverse environmental conditions and pathogen ingress resulting in huge losses to yield and productivity. Therefore, plans are continuously evolving complex regulatory networks to respond to these environmental changes. Due to its ...

Abstract:
... The end-Permian mass extinction is the greatest biotic crisis in Earth history causing the extinction of a large number of marine and terrestrial animals globally. However, how land plants responded to the catastrophe remains controversial. The successive plant-bearing beds in China provide a unique window into the great vegetation change through the critical Permian–Triassic time interval. A nota ...

Abstract:
... Pathogen avirulence (Avr) effectors interplay with corresponding plant resistance (R) proteins and activate robust plant immune responses. Although the expression pattern of Avr genes has been tied to their functions for a long time, it is still not clear how Avr gene expression patterns impact plant‐microbe interactions. Here, we selected PsAvr3b, which shows a typical effector gene expression pa ...
