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.
