Functional characterization of genes mediating cell wall metabolism and responses to plant cell wall integrity impairment

Biological Studies, Publication / /

Author: Issariya Chairam et. al. Publication Type: BMC Plant Biology Year: 2019 Abstract: Background Plant cell walls participate in all plant-environment interactions. Maintaining cell wall integrity (CWI) during these interactions is essential. This realization led to increased interest in CWI and resulted in knowledge regarding early perception and signalling mechanisms active during CWI maintenance. By contrast, knowledge […]
