🌱 Primary or secondary cell wall?

Primary walls surround growing cells. Secondary walls provide additional strength in specialised cells and tissues. Different structures for different jobs.

#PlantWallK #PlantCellWall #PlantBiology #PlantDevelopment #CellWallResearch
Growing plant cells produce a primary cell wall around themselves. Some cells add a sturdy secondary cell wall to protect themselves against pathogens and drought. The strength of the secondary cell wall is primarily provided by lignin (and the size of the wall). The plant cell, with a vacuole in blue, is shown in the middle.

🌲 New article in @aobp.bsky.social presents a simple method to visualize cellular changes during organ shedding, offering new insights into the plant abscission zone.

Full #openaccess
👉 doi.org/rbkp

#PlantScience #PlantDevelopment
Developmental series of floral organ abscission in wild-type and mutant Arabidopsis. The first open bud was defined as position 1 (P1) (Bleecker and Patterson 1997). Abscission position (mean ± SEM) is indicated in the lower right of each panel. Representative phenotypes are shown. (a) Wild-type Col-0 flowers abscise between P6 and P7. (b) bop1-6D exhibits early abscission. (c) ath1-3 shows delayed abscission and retention of floral organs. (d) rbohD rbohF shows slightly accelerated abscission. Scale bars = 5 mm.
