N2 - Temperature-sensitive mutants of rice, designated virescent (v1, v2 and v3), develop chlorophyll-deficient leaves at a restrictive temperature (20°C) but develop nearly normal green leaves at a permissive temperature (30°C). Analysis of the chlorophyll biosynthetic pathway in the virescent mutants indicated that the chlorophyll deficiency at the restrictive temperature was due to specific blockage of the C5-pathway. Northern analysis suggested that the chlorophyll deficiency in the virescent mutants was caused by specific inhibition of the expression of chloroplast tRNAGlu.
