A single-gene recessive mutant which displays increased phototropic and gravitropic responses has been isolated in Pisum sativum L. cv. Torsdag and is provisionally named mtr-1, for its modified tropic response. Mutant plants attain a greater degree of bending during both phototropic and gravitropic induction due to an extension of the curvature phase. In addition to their increase in tropic curvature, mutant plants have longer and narrower leaves as mature plants, attenuated blue-light-induced ion flux responses, and lower levels of PsPK5 mRNA (a PHOT1 orthologue). Possible causes of these effects are discussed.
