In this context, we must emphasize that Angeles-Núñez and Tiessen have shown that SUS2 and SUS3 are required for channeling carbon toward ADP-glucose and starch in Arabidopsis seeds.1 p.application/pdfengStarch biosynthesisCellulose biosynthesisSucrose synthase activityArabidopsisReply to Smith et al.: No evidence to challenge the current paradigm on starch and cellulose biosynthesis involving sucrose synthase activityinfo:eu-repo/semantics/otherinfo:eu-repo/semantics/openAccess
