Plant hormone salicylic acid (SA) plays critical roles in defense signaling against biotrophic
pathogens. Pathogen inoculation leads to SA accumulation in plants. SA activates a …

Key message OZF1 promotes the transcription of MRD1, which is essential for SA-mediated
defense against virulent and avirulent bacterial pathogens in Arabidopsis. Abstract Salicylic …

Plant hormones regulate growth, development, and defense against biotic and abiotic
stresses. Salicylic acid (SA), ethylene (ET), and jasmonate (JA) are major phytohormones …

Plant defenses against pathogens and insects are regulated differentially by cross-
communicating signal transduction pathways in which salicylic acid (SA) and jasmonic acid …

Salicylic acid (SA) is a potent inducer of defense gene expression in plants, but how SA
activates transcription has been controversial. In this issue of Cell, Ding et al. show that the …

Abstract Salicylic acid (SA) or 2-hydroxybenoic acid is a phenolic plant hormone that plays
an essential role in plant defense against biotrophic and semi-biotrophic pathogens. In …

Salicylic acid (SA) is an essential hormone in plant immunity, but its receptor has remained
elusive for decades. The transcriptional coregulator NPR1 is central to the activation of SA …

Plants are endowed with innate immune system to protect against invading pathogens. The
innate immune system serves as a surveillance system against possible attack by viral …

The phytohormone salicylic acid (SA) plays a pivotal role in plant defense against biotrophic
and hemibiotrophic pathogens. NPR1 and EDS1 function as two central hubs in plant local …

Salicylic acid is an important signal molecule in plant defense. In the past two years,
significant progress has been made in understanding the mechanism of salicylic-acid …
