Common smut caused by is one of the dominant fungal diseases in plants. The resistance mechanism to infection involving alterations in the cell wall is poorly studied. In this study, the resistant single segment substitution line (SSSL) R445 and its susceptible recurrent parent line Ye478 of maize were infected with , and the changes in cell wall components and structure were studied at 0, 2, 4, 8, and 12 days postinfection.

It is promising to improve both plant biomass production and stress resistance simultaneously by genetic modification of cell walls. Here, we report the functions of a UDP-galactose/glucose epimerase 3 (OsUGE3) in rice growth and salt tolerance by characterizing its overexpressing plants (OsUGE3-OX) and loss-of-function mutants (uge3).
