Article Synopsis
- Glucuronoxylan, primarily found in dicot secondary cell walls, stabilizes plant structure through interaction with cellulose; its O-acetylation is key for maintaining this stability.
- The enzyme ESKIMO1/TBL29 acts as the primary xylan O-acetyl transferase in Arabidopsis stems, and its absence leads to stunted growth and structural issues in xylem vessels.
- Analysis of the eskimo1 mutant revealed changes in the expression of genes related to aliphatic glucosinolates (GSLs), with increased levels of certain GSLs and metabolites, indicating metabolic reprogramming tied to the plant's growth issues.
Article Synopsis
- Lignin and xylan are crucial for the structure of plant cell walls and their ability to be digested; previous research focused on modifying them separately but not together, which this study addresses.
- The researchers created a specific plant line, named HrGHypAc, that combines mutations in lignin processing and overexpression of an enzyme that modifies xylan, resulting in increased cellulose and better digestibility compared to the wild type.
- The findings indicate that modifying both lignin and xylan together improves the plant’s cell wall properties, making it easier to break down polysaccharides, which can have potential applications in biofuel production and other industries.
Article Synopsis
- Plant cell wall-derived oligosaccharides (DAMPs), such as xylo-oligosaccharides (XOS), are produced in response to pathogens or during plant development, affecting immunity and cell wall structure.
- Treatment of Arabidopsis with xylobiose (XB) led to significant immune responses, including increased reactive oxygen species (ROS), enhanced MAPK activation, and callose deposition.
- RNA sequencing showed that XB treatment rapidly altered gene expression related to plant immunity and cell wall composition, indicating that XOS can effectively act as a DAMP and influence physiological responses over time.
Morpho-biochemical characterization of a RIL population for seed parameters and identification of candidate genes regulating seed size trait in lentil ( Medik.).
Front Plant Sci
February 2023
The seed size and shape in lentil ( Medik.) are important quality traits as these influences the milled grain yield, cooking time, and market class of the grains. Linkage analysis was done for seed size in a RIL (F) population derived by crossing L830 (20.

To unfold the pathways regulating seed size in lentils, a transcriptomic approach was performed using large-seeded (L4602) and small-seeded (L830) genotypes.

Xylan acetylation pattern is governed by Golgi and extracellular localized acetyl xylan esterase (AXE). We investigated the role of Arabidopsis clade Id from the GDSL esterase/lipase or GELP family in polysaccharide deacetylation.
