The evolution of Proteomics in the genus Flaveria

ABSTRACT: C4 photosynthesis overpasses C3 by a higher photosynthetic rate, along with a higher water and nitrogen use efficiency. The establishment of C4 photosynthesis requires modification of ancestral C3 in both anatomical and metabolic aspects, both are involved in many functional pathways which have not been fully demonstrated. This study aims to illustrate overall functional changes along the evolution of C4 photosynthesis, with a purpose to gain an overall view of what are required for C4 photosynthesis. To achieve this, this study assembled chromosome scale of genome sequencing of five Flaveria species, representing gradual evolutionary stages of C4 photosynthesis from C3 to C3-C4 and to C4. Here, result showed that the genome size gradually increases from C3 to intermediate to C4 species, which ranges from 0.5 G to 1.87 G. The enlarged genomes are mainly from transposable elements, with the number of protein coding gene are comparable along evolution. The copy of C4 version CA1 and PEPC1, as well as PEPC-k gained extra one, two and five copies in C4 species F. trinervia as a result of tandem duplication, which plays a positive role for the emergency of C4 photosynthesis. Besides, the evolutionary pattern of C4 gene on transcript abundance are consistent with that on protein abundance, suggesting transcriptional regulation is a key factor for establishing C4 photosynthesis.

The evolution of TF-regulatory network of core C4 metabolic pathway genes in the genus of Flaveria [low CO2]

Project description:C4 photosynthesis was evolved from ancestral C3 photosynthesis by recruited pre-existed genes to perform new functions. Enzymes and transporters required for C4 metabolic pathway has been well documented, however, transcriptional factors (TFs) that regulate those C4 metabolic genes is poorly understood, in particular, how the TF regulatory network of C4 metabolic genes was re-wired, and the involved metabolic functions of those TFs along the evolution of C4 photosynthesis remained unknown. Here, by using RNA-Seq data from growth condition that reported to have effect on C4 photosynthesis, we constructed the TF regulatory network for four evolutionarily closely related species in the genus Flaveria, which represent different stages of the evolution of C4 photosynthesis, namely, C3, type I C3-C4, type II C3-C4 and C4. Our results show that four TFs are conserved along the evolution whose function either relate to stress response or light response. TFs regulating C4 core genes in C3 species involved in functions belong to RNA regulation and nitrogen metabolism, and that in both intermediate species and C4 species involved in photosynthesis and light responsiveness. Moreover, the TF-network of C4 core metabolic genes has the highest network density in type I C3-C4 species and C4 species when consider the fragment of TF-regulatory network that up-regulated under low CO2, suggesting that TFs regulating C4 genes were recruited to photosynthesis at type I C3-C4 both in involved functions and network density. Our results provide a valuable resource for studying molecular regulatory mechanisms underlying C4 metabolic process.

Gene expression in the development of C3 and C4 Atriplex and C3 Atriplex prostrata x C4 Atriplex rosea F1 hybrids

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.

Exploring the mechanism of C4 photosynthetic differentiation through a unified comparative analysis of maize and rice leaf transcriptomes

Project description:Maize and rice are the two most economically important grass crops and utilize distinct forms of photosynthesis to fix carbon: C4 and C3 respectively. Relative to C3 photosynthesis, C4 photosynthesis reduces photorespiration and affords higher water and nitrogen use efficiencies under hot arid conditions. To define key innovations in C4 photosynthesis, we profiled metabolites and gene expression along a developing leaf gradient. A novel statistical method was implemented to compare transcriptomes from these two species along a unified leaf developmental gradient and define candidate cis-regulatory elements and transcription factors driving photosynthetic gene expression. We also present comparative primary and secondary metabolic profiles along the gradients that provide new insight into nitrogen and carbon metabolism in C3 and C4 grasses. These resources, including community viewers to access and mine these datasets, will enable the elucidation and engineering of C4 photosynthetic networks to improve the photosynthetic capacity of C3 and C4 grasses.

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.
