TLDR
Compared with the dicots, grasses exhibit a relatively conserved but nevertheless divergent transcriptional regulatory program to activate their secondary cell wall development and to coordinate secondary wall biosynthesis with other physiological processes.Abstract:
Secondary cell walls mediate many crucial biological processes in plants including mechanical support, water and nutrient transport and stress management. They also provide an abundant resource of renewable feed, fiber, and fuel. The grass family contains the most important food, forage, and biofuel crops. Understanding the regulatory mechanism of secondary wall formation in grasses is necessary for exploiting these plants for agriculture and industry. Previous research has established a detailed model of the secondary wall regulatory network in the dicot model species Arabidopsis thaliana. Grasses, branching off from the dicot ancestor 140-150 million years ago, display distinct cell wall morphology and composition, suggesting potential for a different secondary wall regulation program from that established for dicots. Recently, combined application of molecular, genetic and bioinformatics approaches have revealed more transcription factors involved in secondary cell wall biosynthesis in grasses. Compared with the dicots, grasses exhibit a relatively conserved but nevertheless divergent transcriptional regulatory program to activate their secondary cell wall development and to coordinate secondary wall biosynthesis with other physiological processes.read more

TL;DR: Here, the natural resistance of plant cell walls to microbial and enzymatic deconstruction is considered, collectively known as “biomass recalcitrance,” which is largely responsible for the high cost of lignocellulose conversion.

WRKY transcription factors.
TL;DR: It is becoming clear that a single WRKY transcription factor might be involved in regulating several seemingly disparate processes, and that members of the family play roles in both the repression and de-repression of important plant processes.

Coordination of carbon supply and plant growth

TL;DR: Evidence is described for the existence of regulatory mechanisms that coordinate carbon supply and use, and the likely central role of sugar signalling is described, and both 'acute' and 'acclimatory' responses to alterations in carbon supply are proposed.

A battery of transcription factors involved in the regulation of secondary cell wall biosynthesis in Arabidopsis.
TL;DR: It is demonstrated that a transcriptional network consisting of S ND1 and its downstream targets is involved in regulating secondary wall biosynthesis in fibers and that NST1, NST2, VND6, and VND7 are functional homologs of SND1 that regulate the same downstream targets in different cell types.

TL;DR: An Arabidopsis thaliana line that is mutant for the R2R3 MYB gene, AtMYB4, shows enhanced levels of sinapate esters in its leaves, indicating that derepression is an important mechanism for acclimation to UV‐B in A.thaliana.
