Dissection of the IDA promoter identifies WRKY transcription factors as abscission regulators in Arabidopsis
WRKY transcription factor-binding sites contribute to the transcriptional regulation of IDA . WRKY57 modulates abscission via redundant IDA/IDA-like peptides.

rrtf1 mutant retained most of the core touch-responsive program. However, DE genes in rrtf1 mutant are enriched for WRKY binding sites. Pulling published DAP-seq data, we showed that there is a strong overlap btw RRTF1 regulated genes & genes bound by WRKY & touch responsive genes. #PlantScience
WRKY motifs are enriched in promoters of DE genes in WT but not in rrtf1 mutant. There is regulatory link between RRTF1 regulated genes and WRKY regulated genes.

Ancient polyploidization waves as evolutionary shields for angiosperms
Chen et al. identified 132 whole-genome duplications (WGDs) clustered around environmental crises. We highlight how, over longer evolutionary timescales, ancient WGDs convergently retained MADS-box, MYB, WRKY and HSF transcription factors, building stress-adaptation networks. These insights guide climate-resilient crop improvement through comparative genomics and CRISPR engineering.

Fig. 2 (shortened, full legend in paper): Perturbations of SlMYB41, SlMYB92, and SlWRKY71 expression affect the suberization of tomato exodermis. (A) Percentage of cross-sections showing a non-suberized, an early suberized (suberin in <50% of exodermal cells), or a late suberized (suberin in >50% of exodermal cells) exodermis phenotype in hairy root cultures of the control (empty vector), CRISPR knockout lines [Slmyb41-ko, Slmyb92-ko, Slwrky71-ko(4), and Slwrky71-ko(5)], and overexpressing lines (SlMYB41-OX, SlMYB92-OX, and SlWRKY71-OX). The number above the bars represents the number (n) of individual roots examined in each genotype. Asterisks denotes statistically significant differences between each line in comparison with the empty vector control, whereas n.s. indicates no significant differences (P<0.05, χ2 test).

The cover illustration shows a pangenome-informed landscape of WRKY structural diversity and regulatory functions across Oleaceae. A circos plot illustrates multi-genome integration and structural variation. Bouquets of Oleaceae flowers represent pigmentation, scent, and stress adaptation, while WRKYGQK-marked butterflies depict WRKY binding and regulatory networks that connect genomic variation with downstream metabolic pathways and adaptive phenotypes.
