Wuschel and W40 Expression Analysis Undergoing Different Lc Locus Background in Tomato

Abstract:

In tomato fruits, the number of locules varies from two to up to 10 or more. lc is relative to fruit size and locule number. As a candidate gene underlying lc, wuschel was mapped to the same region as lc. MLK1 with locule numbers up to 10 and FL1 with locule numbers 2-4, are selected to identify the type of lc loci, the expression of wuschel. MLK1 lc belongs to lc-mutant type and FL1 is lc-wild type. Wuschel is completely same in MLK1 and FL1, but expresses differentially. With the development of flower buds, wuschel expression decreased in both materials stem apex, meanwhile it was higher in MLK1 than FL1 at the corresponding development stage of flower bud. Therefore, these results suggest that wuschel is more possible for candidate gene underlying lc to regulate locule numbers. These results will provide important information for lc regulating locule number in tomato.
