THE COSTATA MUTANT IN THE PEA CAUSED BY MUTATION IN THE LOCA lum-1, lum-2, lum-3, lum- 4, and lum-5.

Abstract
The costata mutant in the pea is characterized by green veins and yellowish
green interveinal areas. Eleven cases of
induced mutation have been reported and possibly one spontaneous. Eight of these
induced cases was found to be due to
mutation in the newly assigned gene lum-2, type- line assigned 5160, one to mutation in a previously investigated gene lum, here
reassigned lum-1. Three mutants were found to be due to mutation in three different loca,
different also from lum-1 and lum-2. These were assigned the symbols lum - 3, type-line
5443, lum - 4, type-line 5609, and lum-5,
type-line 5937. Two further mutants probably belong to two further different loca but gene symbolization is pending further investigations.
