TL;DR: The data suggest that HY5-dependent regulation of PFG gene expression contributes to the establishment of UV-B tolerance, and the bZIP transcriptional regulator ELONGATED HYPOCOTYL5 (HY5) is required for the transcriptional activation of the PFG1/MYB12 and PFG3/MYb111 genes underUV-B and visible light.

TL;DR: A major role of MKP1 and PTP1 is indicated in repressing salicylic acid biosynthesis in the autoimmune-like response caused by SNC1, which is largely the disease resistance gene homolog SUPPRESSOR of npr1-1, CONSTITUTIVE 1 that is absent in the Wassilewskija accession.

TL;DR: Pep1 generation was detected within 30 s after the injury, peaking at 5 min and lasting up to 1 hour in two wound model experiments on Arabidopsis seedlings, and Screening with various protease inhibitors revealed the involvement of metacaspases in Pep1 formation.

TL;DR: It is proposed that clathrin-dependent internalization of ligand-activated receptor kinases into a common endosomal pathway facilitates the responses required for full plant immunity, and that immunity mediated by pattern recognition receptors depends onClathrin, a critical component for the endocytosis of signaling competent receptors into acommon endosomes.

TL;DR: In this article, the authors show that loss of MAP kinase phosphatase 1 in the mutant MKp1 results in hypersensitivity to acute UV-B stress, but without impairing UV-b acclimation.
