New lv Mutants of Pea Are Deficient in Phytochrome B.

abstract：:The cyanobacterial CO2-concentrating mechanism (CCM) allows photosynthesis to proceed in CO2-limited aquatic environments, and its activity is modulated in response to inorganic carbon (Ci) availability. Real-time reverse transcriptase-PCR analysis was used to examine the transcriptional regulation of more than 30 CCM...
