Description:
Single basepair substitution mutant isolated from EMS-mutagenized Arabidopsis Col-gl1 ecotype, using the chlorophyll accumulation assay (Burke et al. Plant Physiol. 123, 575-588, 2000). The mutant was backcrossed to Col-gl wild type at least three times before genetic and physiological characterization. The recessive nature of the mutation was evaluated using F1 seedlings from a backcross, whereas the segregation ratios of mutant phenotype were assessed using F2 seedlings.

Plants are highly susceptible to moderately elevated temperatures and defective in both acquired and basal thermotolerances. Growth and development of plants at all stages are arrested after prolonged exposure to temperatures above 30C (which are permissive conditions for wild-type plants). Photosynthetic capability, as measured by chlorophyll content (chl a/b ratios) and PSII quantum yield, is greatly reduced in leaves when exposed to the moderately high temperature of 30C. The inability of dark germinated seeds to develop green cotyledons and the thermosensitive chlorotic phenotype developed in true leaves after 30C exposure, indicate that chlorophyll accumulation and the photosynthetic apparatus in the plants are sensitive to moderate high-temperature stress. Under high light conditions, plants show no significant difference in photosynthesis capacity compared to the wild type. Plants lack trichomes on leaves and stems, due to the glabrous (gl1) genetic background.
