The cuticle regulates transpirational pull and apoplastic transport of salicylic acid. Sterols and sphingolipids control plasmodesmatal permeability, while glycerol-3-phosphate stabilizes trans-acting siRNA 3a - Liu et al.

Fig. 1 (shortened, full legend in paper): Simplified scheme showing biosynthesis of major plant lipids in plants. Acetyl-CoA carboxylase (ACC) and fatty acid synthase (FAS) complexes are critical enzymes in fatty acid (FA) biosynthesis. In plants, FAS is a multiprotein complex comprising various enzymes responsible for acyl transfer, carbon chain elongation, and reaction termination. The initial condensation reaction is facilitated by β-ketoacyl-ACP synthase III (KASIII), while the six subsequent condensation steps are carried out by KASI, resulting in the production of C16:0. This product is elongated to C18:0 by the action of KASII. The C18:0 is then desaturated to C18:1, a process mediated by the stearoyl-acyl carrier protein (ACP) desaturase encoded by SSI2.

🧪🌾News - How do trees know when winter has really begun?

New research from the Bhalerao group in @natcomms.nature.com shows that trees don’t just count cold hours - they also use brief warm spells early in winter.

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.
