¡¾ÕªÒª¡¿Plant species exhibit substantial variation in leaf morphology.We isolated a recessive mutant gene termed small and cordate leaf 1 (scl1) that causes alteration in both leaf size and shape of cucumber.Compared to wild type leaves,the scl1 mutant had fewer numbers

of

epidermal

pavement

cells.A

single

nucleotide

polymorphism was associated with this leaf phenotype,which occurred in a putative nucleoside bisphosphate phosphatase.RNA-seq analysis of the wild type and scl1 mutant leaves suggested that SCL1 regulation may not involve known hormonal pathways.Our work identified a candidate gene for SCL1 that may play a role in leaf development. ¡¾×ÜÒ³Êý¡¿6Ò³(736-741) ¡¾¹Ø¼ü´Ê¡¿
