    content among the cell lines. The analysis of the transgenic cell lines showed that tomato SlAKR4B has enzyme activities toward D-galacturonic acid as well as glyceraldehyde and glyoxal, suggesting that the SlAKR4B gene encodes a functional enzyme in tomato. Gene expression of SlAKR4B was induced by NaCl, H2O2, and plant hormoneshormonesSubject Category: Chemicals and Chemical Groups
