Arabidopsis MERI-5 and TCH4 and cauliflower isoenzymes expression occur in dense cytoplasmic tissues predominantly involved in the assembly of new cell walls and thus in the integration of newly secreted xyloglucan into the cell wall |
| 2.4.1.207 | donor xyloglucan + xyloglucan acceptor |
the xyloglucan:xyloglucosyl transferase gene TCH4 is strongly upregulated by environmental stimuli, enzyme may function in modifying cell walls to allow growth, airspace formation, the development of vasculature, and reinforcement of regions under mechanical strain, TCH4 protein may contribute to the adaptive changes in morphogenesis that occurs in the organism following exposure to mechanical stimuli |
| 2.4.1.207 | donor xyloglucan + xyloglucan acceptor |
2 isoenzymes: sXET from seeds plays a role in degrading xyloglucan reserves in seeds during germination, eXET from epicotyls is engaged in cell wall rearrangement and integration of new xyloglucan molecules into the preexisting cell wall structure during growth |
| 2.4.1.207 | donor xyloglucan + xyloglucan acceptor |
multifunctional role in cell wall construction, role in restructuring primary cell walls at the time when secondary wall layers are deposited, probably creating and reinforcing the connections between the primary and secondary wall layers |
| 2.4.1.207 | donor xyloglucan + xyloglucan acceptor |
XETs encoded by a gene family may influence plant growth and development, low pH would limit XET function in vivo |
| 2.4.1.207 | donor xyloglucan + xyloglucan acceptor |
role in elongation-growth and other processes involving xyloglucan metabolism |
| 2.4.1.207 | donor xyloglucan + xyloglucan acceptor |
enzyme is unlikely to play a role in acid-induced wall loosening but may function in cold acclimation or cold-tolerant growth, TCH4 expression is rapidly regulated by mechanical stimuli, temperature shifts, light and hormones, it may be involved in assembling nascent cell walls or reinforcing existing and expanding walls |
| 2.4.1.207 | donor xyloglucan + xyloglucan acceptor |
NtXET-1 is involved in the incorporation of small xyloglucan molecules into the cell wall by transglycosylation, role during differentation and growth of the vascular tissue, reduced NtXET-1 expression and increase in the MW of xyloglucans in older leaves might be associated with strengthening of cell walls by reduced turnover and hydrolysis of xyloglucan, control of NtXET-1 expression in leaves |
