Abstract:
A collection of 75 putative mutants with alterations in leaf pigmentation was visually selected from Arabidopsis thaliana plants (M(2) generation) grown at 26 degrees C from seeds treated with the mutagen ethylmethanesulfonate. Fifty-eight of the plants were found to have chlorophyll contents decreased by at least 10% from the parental Columbia ecotype. These plants were screened for chlorophyll content and the ratio of chlorophyll b/a after growth at 20 or 26 degrees C. Relative to the parental type, a significant number of individuals in which the chlorophyll-deficient phenotype was exacerbated at one of the growth temperatures were identified. We conclude that temperature-sensitive phenotypic plasticity for chlorophyll content is relatively common in mutant populations of higher plants.

Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
