The rice plastid genes psaA and psaB encoding the two apoproteins ofP700 chlorophyll a protein complex of photosystem I reac-tion center, and the putative rpsl4 gene for ribosomal protein Sl4, are organized into a transcription u it. Northern blot analyses revealed that the polycistronic m

of chloroplasts, etioplasts, chromoplasts and the undifferentiated plastids from a tobacco BY2 cell culture and currently features 2793 protein entries. plprot furthermore provides an interactive rice etioplast proteome map that allows protein quanti-fication and the analysis of proteome dynamics during light

DDBJ/EMBL/GenBank accession no. AB005290 A full-length cDNA encoding a putative σ factor for a plastid RNA polymerase was isolated from the higher plant Oryza sativa. The nucleotide sequence of the corresponding nuclear gene, named Os-sigA (O.sativa sigma A), predicts a polypeptide of 519 amino

analyzed by immunoblotting methods and their activities in early growth phase of the cells. Cytosolic type GS (41 kDa subunit) and NADH-GOGAT were the major isoforms in the rice cells grown in normal R-2 medium. However, contents of plastid type GS (44 kDa subunit) and Fd-GOGAT increased in response to NOf

Plastids are descended from a cyanobacterial symbiosis which occurred over 1.2 billion years ago. During the course of endosymbiosis, most genes were lost from the cyanobacterium’s genome and many were relocated to the host nucleus through endosymbiotic gene transfer (EGT). The issue of how many

ABSTRACT The effect of Protox expression site on herbicidal resistance was investigated in wild-type and transgenic rice plants imposed by peroxidizing herbicide oxyfluorfen. The transgenic rice systems involved the plastidal expression of Arabidopsis protoporphyrinogen oxidase (Protox; AP line

The transcription of rice plastid psbD-psbC genes en-coding photosystem II reaction center protein D2 and chlo-rophyll a-binding protein CP43 is closely regulated by light. To elucidate the sequence requirement for the light-re-sponsive promoter of psbD-psbC operon, transcriptional analysis

Photosynthesis is the final determinator for crop yield. To gain insight into genes controlling photosynthetic capacity, we selected from our large T-DNA mutant population a rice stunted growth mutant with decreased carbon assimilate and yield production named photoassimilate defective1 (phd1
