(Submitter supplied) A. thaliana lines with reduced lignin content through down-regulation of the lignin biosynthesis enzymes cinnamoyl CoA reductase (CCR) exhibit extensive cell wall remodeling which results in the release of a mixture of pectic oligosaccharide elicitors of pathogenesis-related (PR) protein gene expression through the salicylic acid signaling pathway. Loss of function of FERONIA, a CrRLK1-like subfamily receptor-like kinase resulted in loss of PR-1, -2 and- 5 gene activation in stems of the ccr1/fer-4 double mutant.

(Submitter supplied) The cell wall is a defining feature of plant cells and glues cells to each other. To overcome this physical constraint, plants must process and disconnect cell wall linkages during growth and development. However, little is known about the mechanism guiding cell-cell detachment and cell wall remodeling. Here, we identify two neighboring cell types in Arabidopsis that coordinate their activities to control cell wall processing, thereby ensuring precise abscission to discard organs. more...

(Submitter supplied) The cell wall is a crucial structure in plant cells, and modifications in its composition often have a major impact on growth and development. However, the molecular mechanisms responsible for the negative effects of cell wall alterations on plant growth are largely unknown. It was previously shown that a reduction in the levels of de-esterified homogalacturonan, a major pectin component of cell walls, in Arabidopsis thaliana plants expressing a fungal polygalacturonase or mutated in the QUASIMODO2 gene (qua2-1 plants), cause severe growth defects. more...

(Submitter supplied) affy_ccr_maize - affy_ccr_maize - Cinnamoyl-CoA reductase (CCR) catalyzes a key step in monolignol biosynthesis. We show that downregulation of CCR in maize was associated with lower lignin content and a strong decrease in H units. Concomitantly, these cell wall modifications were associated with higher digestibility. On another hand, immunocytochemistry indicated a modification of lignification pattern and cellulose content. more...

(Submitter supplied) Cellulose from plant biomass is the largest renewable energy resource of carbon fixed from the atmosphere, which can be converted into fermentable sugars for production into ethanol. However, the cellulose present as lignocellulosic biomass is embedded in a hemicellulose and lignin matrix from which it needs to be extracted for efficient processing. Here, we show that expression of an Arabidopsis transcription factor SHINE (SHN) in rice, a model for the grasses, causes a 34% increase in cellulose and a 45% reduction in lignin content.

(Submitter supplied) Purpose: To investigate the global impact of lignin perturbation on transcription in plants, we analyzed transcriptomes from rapidly lignifying stem tissue in wild-type Arabidopsis and 13 selected mutants. Methods: RNA-sequencing was conducted to profile the transcriptome in basal stem tissue of Arabidopsis plants. PolyA+ RNA libraries were constructed and paired-end sequencing was performed on Illumina NovaSeq 6000. more...

(Submitter supplied) Polygalacturonase-inhibiting proteins (PGIPs) in plant cell walls inhibit fungal endopolygalacturonases (ePGs). Their action directly limits the effective ingress of the pathogen and is thought to lead to an up-regulated defense response. We previously showed that, PGIP activity, ePG inhibition and decreased Botrytis cinerea susceptibility were correlated in tobacco plants over-expressing grapevine (Vitis vinifera) Vvpgip1. more...
