🥔🧬In potato roots, the exodermis forms a continuous suberin layer near the tip—earlier than the endodermis. Reducing suberin altered mineral levels & stunted growth

This outer barrier helps control ion balance in a major food crop #plantscience @jxbotany.bsky.social academic.oup.com/jxb/article-...
Exodermal suberin contributes to ion homeostasis and growth in potato
In potato roots, the endodermis and exodermis define anatomical compartments for mineral nutrients. Exodermal suberin accumulates early, and its reduction

It’s FINALLY out!
We investigated the natural variations for endodermal suberin and identified SUBER GENE1 (SBG1)- Type One Protein Phosphatases (TOPPs) as a novel module that regulates endodermal suberization.

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.

(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).

Suberin-rich roots can increase🌱stress resilience &help sequester carbon in the soil. We mapped the complete development of "plant amor" suberin-rich root phellem cells via single-nuclei sequencing and found a new regulator. #PlantScience @salkinstitute shorturl.at/ZFqLw
A single-nuclei transcriptome census of the Arabidopsis maturing root identifies that MYB67 controls phellem cell maturation
Using small nuclear RNA sequencing (snRNA-seq), Miller et al. produced a gene expression census of the maturing Arabidopsis root and, by exploring the development of the suberizing phellem, identify that MYB67 controls phellem cell maturation. This census may serve as resource for engineering future plants with improved stress resilience and carbon capture capacity.
