Melatonin treatment delays postharvest senescence and regulates reactive oxygen species metabolism in peach fruit
Identification of early salt stress response genes in tomato root by suppression subtractive hybridization and microarray analysis.
High salinity is one of the most serious threats to crop production. To understand the molecular basis of plant responses to salt stress better, suppression subtractive hybridization (SSH) and…
Metabolic engineering of geranic acid in maize to achieve fungal resistance is compromised by novel glycosylation patterns.
Identification and characterization of a strict and a promiscuous N-acetylglucosamine-1-P uridylyltransferase in Arabidopsis.
A three-dimensional protein structure model using the human AGX1 as template showed a conserved catalytic fold and helped identify key conserved motifs, despite the high sequence divergence, to identify new roles of amino sugar metabolism in plants and specifically their role as signalling molecules.

Considering the common occurrence of linalool and its glycosides in plant tissues, it suggests that plants may balance attractive fragrance with 'poor taste' using the same precursor compound.

Comparing the metabolite profiles of green teas of nine varieties that were plucked in spring, summer, and autumn by using ultraperformance liquid chromatography-quadrupole time-of-flight mass spectrometry on a reversed phase column suggested that several flavonoids and amino acids are mainly responsible for the seasonal variations in taste quality.
Hydrophobic recognition allows the glycosyltransferase UGT76G1 to catalyze its substrate in two orientations
UGT76G1 is an UDP-glucose dependent glycosyltransferase and a component of the biosynthesis pathway for the natural sugar substitute steviol glycoside and insights into substrate recognition and catalysis by the enzyme are provided.

It is suggested that GalAK generates GalA-1-P from the salvaged GalA that is released during growth-dependent cell wall restructuring, or from storage tissue, and is then available for use in the formation of UDP-GalA required for glycan synthesis.

It is shown that the NDXXD catalytic motif of CDS, under the lower substrate conditions prevalent in plants, also catalyzes the next step, converting CPP into chrysanthemol by hydrolyzing the diphosphate moiety.
