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 …

Salicylic acid (SA) is a phytohormone that plays important roles in many aspects of plant life,
notably in plant defenses against pathogens. Key mechanisms of SA signal transduction …

Abstract Plant sulfite reductase (SiR; Enzyme Commission 1.8. 7.1) catalyzes the reduction
of sulfite to sulfide in the reductive sulfate assimilation pathway. Comparison of SiR …

Salicylic acid (SA) plays a central role as a signalling molecule involved in plant defense
against microbial attack. Genetic manipulation of SA biosynthesis may therefore help to …

Salicylic acid (SA) has long been implicated in plant responses to oxidative stress. SA
overproduction in Arabidopsis thaliana leads to dwarfism, making in planta assessment of …

Small ubiquitin-like modifier proteases 1 and 2 (SUMO1/2) have been linked to the
regulation of salicylic acid (SA)-mediated defence signalling in Arabidopsis thaliana. In …

As an essential enzyme in the sulfate assimilation reductive pathway, sulfite reductase (SiR)
plays important roles in diverse metabolic processes such as sulfur homeostasis and …

Sulfate uptake and ATP sulfurylase activity in the roots of Arabidopsis thaliana and Brassica
napus were enhanced by S deprivation and reduced following resupply of SO42–. Similar …

We reported previously that overexpression of a salicylic acid (SA) methyltransferase1 gene
from rice (OsBSMT1) or a SA glucosyltransferase1 gene from Arabidopsis thaliana …

Sulfate transporters present at the root surface facilitate uptake of sulfate from the
environment. Here we report that uptake of sulfate at the outermost cell layers of Arabidopsis …
