Most of the carbon dioxide sequestered by plants during photosynthesis is converted into sugars and stored into polysaccharide-enriched cells walls that constitute the majority of the plant biomass. While plants have long been considered a valuable resource of biomaterials for the chemical and textile…

A forthcoming issue of Current Opinion in Biotechnology features a set of reviews on the topic of lignin, particularly its chemistry and applications. Lignin is a complex set of polymers that provide structural support to vascular plants (See Renault et al. for insights into lignin's evolutionary origins).…

Boron (B) is an essential plant micronutrient that plays a major role in cell wall structure and function by providing cross-linking of the rhamnogalacturonan II (RG-II) pectin component of the cell wall. Under normal pH conditions, B is found principally as boric acid. Although boric acid permeates…

Sorghum (Sorghum bicolor) is the fifth most important cereal crop globally and is considered to be the “camel among crops” due to its ability to flourish in low-nutrient soils and to withstand prolonged drought. Cultivated varieties are phenotypically and morphological diverse. Consequently, sorghum…

Plant cell walls are important for terrestrial lifestyle, providing support and directing the plant growth. The primary and secondary cell walls differ in their chemical composition and flexibility. Secondary cell walls are less perceptive to industrial degradation processes and therefore pose problems…

Cellulose, the most abundant biopolymer on earth, is an important structural component of the primary and secondary cell wall of plant cells. It is also found in animals (tunicates), oomycetes, and bacteria (Kumar and Turner, 2015). Besides providing support and rigidity in living organisms, cellulose…

Arjen Dijkgraaf | Wednesday, July 4, 2018 (Originally published in C2W Boeken. Translation by Google Translate) In poplars a protein appears to have a bizarre double function: it makes building blocks for amino acids but also regulates the production of lignin. It could be a new way to create…

Here’s a fascinating story; starting with an association study, Xie et al. found that a protein previously identified as an enzyme involved in phenylpropanoid metabolism (specifically, 5-enolpyruvylshikimate 3-phosphate synthase, EPSP) also acts as a transcriptional regulator of this pathway, not only…
