Our revised manuscript on the roles of branched xylan and heteromannan (previously available as a preprint) in controlling seed mucilage properties and early growth in salt stress has now been peer-reviewed.
A collaborative study of mannan polysaccharide production in wheat (Triticum aestivum) is now published in the journal Plant Science. Wheat-like polymers that normally accumulate in the developing endosperm of the grain were produced in two heterologous hosts by the expression of a single enzyme, TaCSLA12. Additional mannan-related genes were identified in the wheat endosperm but were not essential for making the polysaccharides in yeast. Moreover, a wheat-like mannan production in a glucomannan-deficient Arabidopsis thaliana triple mutant (csla2 csla3 csla9) did not alter the plant morphology.
Congratulations to our colleagues at INRAE (Nantes, France; who led the study), the Joint BioEnergy Institute (Berkeley, California), Rothamsted Research (UK), and Heinrich Heine University (Düsseldorf, Germany; where our experimental work was conducted).
