Abstract
In Pisum sativum L. a third, more severe, allele at the internode length locus le is identified and named led. Plants homozygous for led possess shorter internodes and appear relatively less responsive to GA20 than comparable le (dwarf) plants. Gene led may act by reducing the 3β-hydroxylation of GA20 to the highly active GA1 more effectively than does gene le. The results indicate that le is a leaky mutant and therefore that endogenous GA1 influences internode elongation in dwarf (le) plants.Keywords
