Analysis of the diurnal expression patterns of the tomato chlorophyll a/b binding protein genes. Influence of light and characterization of the gene family.
Steady-state mRNA levels of the chlorophyll a/b binding (cab) proteins oscillate substantially during a diurnal cycle in tomato leaves. This accumulation pattern is also observed in complete darkness, supporting the hypothesis that the expression of cab genes is at least partially regulated by an endogenous rhythm ("biological clock"). The amplitude of the cab mRNA accumulation is dependent on ...
متن کاملLocalization in the Tomato Genome of DNA Restriction Fragments Containing Sequences Homologous to the rRNA (45s), the Major Chlorophyll a/b Binding Polypeptide and the Ribulose Bisphosphate Carboxylase Genes.
DNA restriction fragments containing sequences homologous to the ribosomal RNA (45s), the major chlorophyll a/b binding polypeptide (CAB) and the small subunit of ribulose bisphosphate carboxylase (RBCS) genes have been localized and mapped in the tomato nuclear genome by linkage analysis. Ribosomal RNA genes map to a single locus, R45s, which resides in a terminal position on the short arm of ...
متن کاملEnvironmental and genetic effects on circadian clock-regulated gene expression in Arabidopsis.
Expression patterns of the cold-circadian rhythm-RNA binding (CCR) and chlorophyll a/b binding (CAB) protein genes have circadian rhythms with phases that are different from each other and are affected differently by cold (4 degrees C) treatment. Cycling of CCR and CAB RNA levels was observed in Arabidopsis seedlings grown for 5 days at 4 degrees C under a light/ dark photoperiod, although the ...
متن کاملIntegration of circadian and phototransduction pathways in the network controlling CAB gene transcription in Arabidopsis.
The transcription of CAB genes, encoding the chlorophyll a/b-binding proteins, is rapidly induced in dark-grown Arabidopsis seedlings following a light pulse. The transient induction is followed by several cycles of a circadian rhythm. Seedlings transferred to continuous light are known to exhibit a robust circadian rhythm of CAB expression. The precise waveform of CAB expression in light-dark ...
متن کاملThe expression of light-regulated genes in the high-pigment-1 mutant of tomato
Three light-regulated genes, chlorophyll a/b-binding protein (CAB), ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit, and chalcone synthase (CHS), are demonstrated to be up-regulated in the high-pigment-1 (hp-1) mutant of tomato (Lycopersicon esculentum Mill. ) compared with wild type (WT). However, the pattern of up-regulation of the three genes depends on the light conditions, st...
