The mechanism uncoupling isoprene emission and photosynthesis under drought was investigated in Populus alba saplings. Isoprene emission, incorporation of 13C into the isoprene molecule, isoprene synthase (ISPS) activity, concentration and gene expression, and photosynthesis were measured as a function of the fraction of transpirable soil water (FTSW) and in plants recovering from drought. Phot...
Halophyte, like Salicornia europaea, could make full use of marginal saline land for carbon fixation. How the photosynthesis of S. europaea is regulated under high salinity implicates a significant aspect to exploit this pioneer plant in future. Measurement of photosynthesis parameters demonstrated the reduction of photosynthesis for the 0 and 800 mM NaCl treated plants are more likely due to n...
It is believed that high levels of mesophyll conductance (gm) largely contribute to the high rates of photosynthesis in herbaceous C3 plants. However, some sclerophyllous C3 plants that display low levels of gm have high rates of photosynthesis, and the underlying mechanisms responsible for high photosynthetic rates in sclerophyllous C3 plants are unclear. In the present study, we examined phot...
Photosynthesis is a crucial biological process that depends on the interplay of many components. This work analyzed the gene targets for 4 transcription factors: FnrL, PrrA, CrpK and MppG (RSP_2888), which are known or predicted to control photosynthesis in Rhodobacter sphaeroides. Chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq) identified 52 operons under direct...
C(4) photosynthesis is a series of biochemical and structural modifications to C(3) photosynthesis that has evolved numerous times in flowering plants, despite requiring modification of up to hundreds of genes. To study the origin of C(4) photosynthesis, we reconstructed and dated the phylogeny of Molluginaceae, and identified C(4) taxa in the family. Two C(4) species, and three clades with tra...
