A rice GT61 glycosyltransferase possesses dual activities mediating 2-O-xylosyl and 2-O-arabinosyl substitutions of xylan
A member of the rice GT61 clade B is capable of transferring both 2-O-xylosyl and 2-O-arabinosyl residues onto xylan and another member specifically catalyses addition of 2-O-xylosyl residue onto xylan.

An Arabidopsis family GT106 glycosyltransferase is essential for xylan biosynthesis and secondary wall deposition
We have demonstrated that the Arabidopsis FRA9 (fragile fiber 9) gene is specifically expressed in secondary wall-forming cells and essential for the synthesis of the unique xylan reducing end sequence.

Independent recruitment of glycosyltransferase family 61 members for xylan substitutions in conifers
Several pine members of the gymnosperm-specific GT61 clades were demonstrated to be arabinosyltransferases and xylosyltransferases catalyzing the transfer of 2-O-Araf, 3-O-Araf and 2-O-Xyl side chains onto xylool...

Functional analysis of GT61 glycosyltransferases from grass species in xylan substitutions
Multiple rice GT61 members were demonstrated to be xylan arabinosyltransferases (XATs) mediating 3-O-arabinosylation of xylan and the functions of XATs and xylan 2-O-xylosyltransferases were shown to be conserved...

Sexual isolation between North American and Bogota strains of Drosophila pseudoobscura
Sexual isolation, the reduced ability of organisms of different species to successfully mate, is one of the reproductive barriers that prevent gene flow between different taxa. Various species-specific signals...

Developmental Isolation and Subsequent Adult Behavior of Drosophila paulistorum. VI. Quantitative Variation in Cuticular Hydrocarbons
Our previous studies have demonstrated that long-term chemical contact with heterospecifics during development minimized unproductive heterospecific matings among the six Drosophila paulistorum semispecies. When ...
