Yang et al. investigate the role of autophagy in the ongoing arms race of plant defense and viral counterdefense. The Plant Cell https://doi.org/10.1105/tpc.18.00122 By Meng Yang and Dawei Li Background: Most plants have defense mechanisms that enable resistance to pathogens. One of theses is…

Chen et al. higlight the importance of AS in diversifying gene function and regulating phenotypic variation. The Plant Cell https://doi.org/10.1105/tpc.18.00109 Background: Alternative splicing (AS) of precursor mRNAs is an essential regulatory mechanism that greatly enhances transcriptome and proteome…

Ma et al. investigate epigenetic aspects of heat-induced male sterility in cotton. By Yizan Ma, Ling Min and Xianlong Zhang Background:  Global warming causes extremely high temperatures in summer in some areas. Certain crops cultivated in summer cannot tolerate extreme heat stress and begin…
