systemical accumulation of xyloglucan endotransglycosylase/hydrolase transcripts following infestation with Myzus persicae. Induction is specific to phloem but not correlated with increase in enzyme activity in phloem
several abundant XTH genes are generally up-regulated during tension formation, including XTH16-36, -21, -14 and -27, while others were suppressed such as XTH16-35. In mature gelatinous fibers, enzyme gene products are detected in the gelatinous layers while the enzyme's endo-transglycosylase activity is found in the adjacent S2 wall layer. Enzyme gene products and activity persist in mature gelatinous fibers for several years
generally, highest transglucosylase activities (gene SIXTH1 - EC 2.4.1.207) during fruit growth, decrease during ripening, accordingly hydrolase activity decrease during ripening as indicated by xyloglucan viscosity decrease, expression of 10 different XTH genes in Solanum lycopersicum: SIXTH12 (group 2) highly expressed during fruit growth, decrease during ripening

the Mt-XTH1 promoter directs expression in cell throughout the root system with significantly higher levels of activity in mycorrhizal roots. Mt-XTH1 expression is elevated not only in the regions of the roots colonized by the fungus, but also at sites distal to the infected regions
enzyme XTH15 is strongly expressed in young, rapidly growing organs, but particularly in 24-h imbibed seeds, the seedling hypocotyl and root, and early-stage flowers (especially in the carpels)

enzyme XTH31 is strongly expressed in young, rapidly growing organs. XTH31 is more specialised, being expressed in fewer organs (24-h imbibed seeds, hypocotyl, root elongation zone, cotyledons and immature leaves), albeit at higher concentrations
