Project description:Elucidating the genetic control of C3 and C4 photosynthesis. Atriplex rosea (C4) and Atriplex prostrata (C3) were at maturity to compare expression between C3 and C4 in leaves, stems, and roots. Their F1 hybrid leaf was studied at maturity and will aid in identifying regulatory elements involved in C3 and C4 leaf development. Two C3 Atriplex prostrata x C4 Atriplex rosea F3 hybrids (F3003 and F3036) were sequenced at a mature leaf stage.
Project description:Elucidating the genetic control of development of C3 and C4 photosynthesis. Atriplex rosea (C4) and Atriplex prostrata (C3) were studied along a leaf developmental gradient to compare development between C3 and C4. C3 Atriplex prostrata x C4 Atriplex rosea F1 hybrid were studied along the same developmental gradient and will aid in identifying regulatory elements involved in C3 and C4 leaf development.

Project description:Hakea prostrata (Proteaceae) maintains a high photosynthetic rate at low leaf phosphorus and exhibits delayed leaf greening, a convergent adaptation found in many plant families where investment in photosynthetic machinery is delayed until after the leaf structure is built, saving on nutrient investment. To identify the dynamics of gene expression underlying delayed greening, we made a de novo transcriptome assembly for H. prostrata using roots and leaves from hydroponically grown plants, and leaves from five morphologically distinct stages of leaf development from wild plants. Abundance of unique transcripts was compared among the developing leaf stages to identify differentially expressed genes, which were separated into groups based on co-expression patterns. In general, transcripts encoding functions associated with leaf structure decreased in abundance across leaf development, with this concomitant with the decline in foliar P and N concentrations. An enrichment of differentially expressed genes associated with photosynthetic function increased in abundance at or after leaf expansion and much later in development than in species that do not have delayed greening. The abundance of transcripts encoding cytoplasmic and mitochondrial ribosomal subunits generally declined across leaf development, whilst transcripts encoding chloroplast ribosomal subunits increased. Taken together, these results indicate a clear shift in protein synthesis apparatus, moving from a leaf developmental stage and into the photosynthetically-active stage.
