In this #OpenAccess Brief Report, Wu et al. describe a novel physiological function of the #Arabidopsis
PPRD1 in #brassinosteroid #biosynthesis, and new possibilities for alternative #steroid reductases involved in steroid #metabolism.

Panel of morphological and statistical data to illustrate findings that overexpression of Arabidopsis POLYPRENOL REDUCTASE 1 (PPRD1) partially rescues the de-etiolated2-1 (det2-1) brassinosteroid biosynthesis mutant phenotype and increases its brassinosteroid contents. A loss-of-function pprd1 mutation enhances the det2-1 short-root phenotype and further reduces its brassinosteroid levels, suggesting that PPRD1 plays a role in brassinosteroid biosynthesis.

Jia et al. report that the horizontally transferred #gene CsMTAN rewires purine traffic to build #caffeine factories in #tea leaves, expanding our understanding of alkaloid #biosynthesis.

Panel of figures representing results of metabolite genome-wide association studies in tea (Camellia sinensis), which identified the 5'-methylthioadenosine/S-adenosylhomocysteine nucleosidase gene CsMTAN. CsMTAN catalyzes the degradation of 5'-methylthioadenosine and S-adenosylhomocysteine, releasing adenine, a precursor in the caffeine biosynthetic pathway. The naturally occurring phenylalanine→tyrosine substitution at residue 179 (F179Y) significantly reduces the catalytic efficiency of CsMTAN.

Left: Predicted gene regulatory network of Streptomyces coelicolor based on 17 well-known regulators. Each node in the network represents a (regulatory) gene, and every edge represents a PWM predicted regulatory interaction between nodes. The edges colored in dark gray indicate strong PWM prediction scores, while the lighter gray shades represent weaker interactions. Matches within BGC regions are depicted as triangles. In six regions (black circled), the matches fall within a co-expressed region, highlighting their functional relation to these compounds. Right: Proposed biosynthetic pathway for assembly of desferrioxamines E and B. Main biosynthetic enzymes presented in bold face. DesG and DesH balance intracellular N-hydroxy-N-succinylcadaverine (HSC) and N-hydroxy-N-acetylcadaverine (HAC) concentrations by converting HSC to HAC. In the absence of DesG and/or DesH, the cells likely fail to produce sufficient levels of HAC, thereby strongly attenuating the production of DFOB. Although DesC has been shown to be able to catalyze the acetylation of N-hydroxycadaverine in vitro, the enzyme can only modestly compensate for the loss of DesH in vivo, underlining the important role played by DesG and DesH in DFOB production.

Diagram of a cell cross-section focused on component interactions between the cytoplasm, nucleus, and amyloplast. Annotations indicate that overexpression of IbNAC22 improves starch and amylose contents, IbNAC22 directly activates the expression of IbGBSSI, a key gene for amylose biosynthesis but suppresses the expression of IbSBEI, a key gene for amylopectin biosynthesis. IbNAC22 directly interacts with IbNF-YA10, while overexpression of IbNF-YA10 significantly improves starch and amylose contents.

Biosynthesis of ascorbic acid in animals and plants
Only humans cannot synthesize ascorbic acid, but plants and animals are very good at this task. In plants, biosynthesis begins with D-glucose, D-fructose is obtained, after D-mannose, from which, through other processes, ascorbic acid is obtained.
In animals, this process occurs differently, everything starts with D-glucose and ends with ascorbic acid.
