Abstract excerpt

Arabidopsis encodes 10 TREHALOSE-6-PHOSPHATE PHOSPHATASE (TPP) genes, homologous to maize RAMOSA3 (RA3), which controls shoot branching. Here, we explored the functions of the Arabidopsis TPPs. We used expression profiling, multiplex CRISPR-Cas9 editing and metabolite profiling to explore the function of Arabidopsis TPP genes. The Arabidopsis TPP genes had distinct expression patterns in shoot apices, with TPPI...
