Transcript inhibition from limited starch degradation

ABSTRACT: In starchless mutants of Arabidopsis, pgm, and wild type, Col0, there are small differences in transcript levels at the end of the day, but large differences at the end of the night. Many of the transcripts of genes involved in biosynthesis and growth are repressed in the pgm mutant (Thimm et al., 2004). It is hypothesized that a transient depletion in sugars at the end of the night inhibits carbon utilization at the beginning of the day (Gibon et al., 2004). In order to test if the same inhibition of transcripts involved in biosynthesis and growth also occurs in starch excess mutants of Arabidopsis, Affymetrix arrays will be generated for WT (Col0), and the following mutants: sex4-3 (Salk 102567), ptpkis2 (Salk 053285), and sex1-3 (Yu et al., 2001). WT, sex4-3, and ptpkis2 plants were
