Abstract
Tomato plants of a single-gene recessive mutant, stamenless-2 (sl2/sl2), bear abnormal stamens but produce near-normal flowers following application of gibberellic acid. Data presented here show that mutant plants have lower levels of extractable gibberellin-like substances in vegetative as well as floral parts compared with normal ones. The significance of these observations in relation to gene-controlled stamen form, and sexuality of plants is discussed.
