摘 要:Helical growth is an economical way for plant to obtain *** classic microtubule–microfibril alignment model of Arabidopsis helical growth involves restriction of the appropriate orientation of cellulose microfibrils appropriately in the cell ***,the molecular mechanism underlying tomato helical growth remains ***,we identified a spontaneous tomato helical(hel)mutant with right-handed helical cotyledons and petals but left-handed helical stems and true *** analysis revealed that the hel phenotype was controlled by a single recessive *** map-based cloning,we cloned the HEL gene,which encodes a cellulose interacting protein homologous to CSI1 of *** identified a 27 bp fragment replacement that generated a premature stop *** experiments showed that the helical growth phenotype could be restored by the allele of this gene from wild-type *** contrast,the knockout mutation of HEL in Pyriforme via CRISPR/Cas9 resulted in helical *** findings shed light on the molecular control of the helical growth of tomato.
