“…C 4 photosynthesis arose from C 3 photosynthesis through a series of events/phases ( Sage, 2004 , 2021 ; Gowik and Westhoff, 2011 ). Combined physiological, molecular, and morphological changes played crucial roles in the evolution of the C 4 photosynthetic mechanism.…”

Cleomaceae is closely related to Brassicaceae and includes C3, C3–C4, and C4 species. Thus, this family represents an interesting system for studying the evolution of the carbon concentrating mechanism. However, inadequate genetic information on Cleomaceae limits their research applications. Here, we characterized 22 Cleomaceae accessions [3 genera (Cleoserrata, Gynandropsis, and Tarenaya) and 11 species] in terms of genome size; molecular phylogeny; as well as anatomical, biochemical, and photosynthetic traits. We clustered the species into seven groups based on genome size. Interestingly, despite clear differences in genome size (2C, ranging from 0.55 to 1.3 pg) in Tarenaya spp., this variation was not consistent with phylogenetic grouping based on the internal transcribed spacer (ITS) marker, suggesting the occurrence of multiple polyploidy events within this genus. Moreover, only G. gynandra, which possesses a large nuclear genome, exhibited the C4 metabolism. Among the C3-like species, we observed intra- and interspecific variation in nuclear genome size as well as in biochemical, physiological, and anatomical traits. Furthermore, the C3-like species had increased venation density and bundle sheath cell size, compared to C4 species, which likely predisposed the former lineages to C4 photosynthesis. Accordingly, our findings demonstrate the potential of Cleomaceae, mainly members of Tarenaya, in offering novel insights into the evolution of C4 photosynthesis.

“…Gene expression analysis predominantly paved the way to understand the difference between derived photosynthetic types (C 2 , C 4 ) and the ancestral C 3 photosynthesis [24,34,35]. Much progress in understanding C 4 and C 2 photosynthesis was achieved by comparing differentially expressed genes of closely related species in the genus Flaveria (Asteraceae) considered as a model organism to study the evolution of C 4 photosynthesis [6,7,[34][35][36][37]. The goosefoot family (Chenopodiaceae) has a large number of C 2 and C 4 species that differ anatomically and ecologically from Flaveria.…”

Amaranthaceae (incl. Chenopodiaceae) shows an immense diversity of C4 syndromes. More than 15 independent origins of C4 photosynthesis, and the largest number of C4 species in eudicots signify the importance of this angiosperm lineage in C4 evolution. Here, we conduct RNA-Seq followed by comparative transcriptome analysis of three species from Camphorosmeae representing related clades with different photosynthetic types: Threlkeldia diffusa (C3), Sedobassia sedoides (C2), and Bassia prostrata (C4). Results show that B. prostrata belongs to the NADP-ME type and core genes encoding for C4 cycle are significantly upregulated when compared with Sed. sedoides and T. diffusa. Sedobassia sedoides and B. prostrata share a number of upregulated C4-related genes; however, two C4 transporters (DIT and TPT) are found significantly upregulated only in Sed. sedoides. Combined analysis of transcription factors (TFs) of the closely related lineages (Camphorosmeae and Salsoleae) revealed that no C3-specific TFs are higher in C2 species compared with C4 species; instead, the C2 species show their own set of upregulated TFs. Taken together, our study indicates that the hypothesis of the C2 photosynthesis as a proxy towards C4 photosynthesis is questionable in Sed. sedoides and more in favour of an independent evolutionary stable state.

Amaranthaceae (incl. Chenopodiaceae) show an immense diversity of C4 syndromes. More than 15 independent origins of C4 photosynthesis, partly in halophytic and/or succulent lineages, and the largest number of C4 species in eudicots signify the importance of this angiosperm lineage in C4 evolution. Here, we conduct RNA-Seq followed by comparative transcriptome analysis of three species from Camphorosmeae representing related clades with different photosynthetic types: Threlkeldiadiffusa (C3), Sedobassiasedoides (C2), and Bassiaprostrata (C4). Results show that B.prostrata belongs to the NADP–ME type and core genes encoding for C4 cycle are significantly up–regulated when compared to Sed.sedoides and T.diffusa, Sedobassiasedoides and B.prostrata share a number of up–regulated C4–related genes, however, two C4 transporters (DIT and TPT) are found significantly up–regulated only in Sed. sedoides. Combined analysis of transcription factors (TFs) of the closely related lineages (Camphorosmeae and Salsoleae) revealed that no C3 specific TFs is higher in C2 species as compared to C4 species, instead the C2 species show their own set of up–regulated TFs. Taken together, our study indicates that the hypothesis of the C2 photosynthesis as a proxy towards C4 photosynthesis is questionable in Sed.sedoides and more in favour of an independent evolutionary stable–state.
