In this study, Zhang et al. (2022) used various techniques to investigate the role of KNAT3 and KNAT7 transcription factors in the synthesis of mucilage pectin in Arabidopsis. They identified a group of genes regulated by these factors that coordinate the formation of specific pectic domains.
Arabidopsis mucilage has been used for more than two decades to investigate and characterize different factors of pectin synthesis and modification. Using cytological, transcriptomic, chemical, and molecular approaches, Zhang et al. (2022) clarify the redundant role of KNAT3 and KNAT7, two KNOX Class II transcription factors, in mucilage rhamnogalacturonan-I (RG-I) biosynthesis through the regulation of a group of genes which coordinate the formation of these specific pectic domains.
