MYB and WRKY transcription factors collaboratively regulate suberin biosynthesis in the tomato root exodermis. Antagonistic interactions may fine-tune suberization or act as a brake on overaccumulation - Jo et al.

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).

CC-NLRs exhibit diverse conformations in the resting state. Figure depicts different NLR resting and activated states. While ZAR1 exists as a monomer bound to its guardees in its resting state, several forms have been observed for the NRC2 helper, including dimers, tetramers, and filaments. While filament-like structures were observed via confocal microscopy for NRC2 upon overexpression in planta, these structures were not detected for its paralog NRC4, suggesting a potentially different resting state configuration for NRC4. Our work suggests that the Pik CC-NLR pair forms a hetero-complex bound to the plasma membrane in its resting state. How effector binding to the integrated domain (ID) of the Pik-1 sensor leads to the activation of the complex remains to be determined.

Scientists long thought the plant cell wall to be dead, but it's an active, even chatty participant in cellular growth, reproduction and responses to infection

Plants have a secret language that scientists are only now starting to decipher
Nature - Signals from the plant cell wall help to orchestrate growth, reproduction and immune function. Can harnessing this molecular cross talk help in creating better crops?

The early hormone signaling network underlying wound-induced de novo root regeneration – Kim and Seo

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪
Box 1 figure from Kim and Seo: Recent developments in our understanding of early wound signaling in the control of DNRR. This schematic represents the key contributions of wound-responsive defense hormones to the DNRR process. Their molecular signaling pathways are graphically summarized in panels A–E. (A) Yan et al. (2023) introduced the key role of the cell wall–localized IRR1 peroxidase in DNRR. (B) Hernández-Coronado et al. (2022) and Tran et al. (2023a) described the trade-off between SA-regulated defense responses and regeneration, which may be conserved across various plant species. (C) Lee et al. (2024) showed that the wound-responsive ESR1 transcription factor strongly promotes ASA1 expression immediately after wounding via its dual mode of action. (D) Veloccia et al. (2016), Li et al. (2020), and Shin et al. (2023) revealed that ethylene regulates DNRR in a stage-specifc manner. (E) Liu et al. (2022) showed that JA, ethylene, ROS, and SA are rapidly activated upon wounding
