As an important plant hormone, jasmonic acid regulates plant defense responses and adaptive growth. When the plant is exposed to pests or other stresses, the active jasmonic…
Master MYCs: MYC2, the jasmonate signaling ‘master switch’
The Plant Cell, The Plant Cell: In BriefTo optimize their fitness in the field, plants need to respond rapidly, specifically and dynamically to an ever-changing and often hostile environment. By integrating external environmental cues with endogenous developmental programs, phytohormones play a critical role in the cross-talk between signal…
A Golgi-released subpopulation of the trans-Golgi network mediates protein secretion in Arabidopsis ($)
Plant Science Research WeeklyThe plant trans-Golgi network (TGN) plays the role of early endosomes and acts as hub for the both secretory and vacuolar trafficking pathways. Two types of TGN, GA-TGN (Golgi-associated TGN) and GI-TGN (Golgi-released independent TGN), have been observed in plants. Here, Uemura et al. explore the cellular…
Mechanism of rice blast fungus recognition revealed
The Plant Cell, The Plant Cell: NewsRice is an important food crop in China, but the damage of rice blast fungus is an important factor affecting the high and stable yield of rice. Liu Jun's research group of the Institute of Microbiology, Chinese Academy of Sciences found in the previous study that when rice blast fungus infects rice,…
R gene-miRNA-phasiRNA regulatory module (Nature Comms)
Plant Science Research WeeklyIn plants, like people, having an overactive immune response is just as bad as having an underactive one. R genes in plants are key immune components that need to be kept quiet until needed. Previous studies have shown that miRNAs are involved in suppressing R gene expression, in a process that is amplified…
Plant Systemic Immunity Comes Full Circle: A Positive Regulatory Loop for Defense Amplification
The Plant Cell, The Plant Cell: In BriefThe plant immune system is effective in conferring resistance to various invading pathogens and pests. Membrane-localized pattern recognition receptors (PRRs) and intracellular nucleotide-binding domain, leucine-rich repeat proteins (NLRs) recognize pathogen-associated molecular patterns and pathogen…
