C4-like photosynthesis and the effects of leaf senescence on C4-like physiology in Sesuvium sesuvioides (Aizoaceae).
2019
Sesuvium sesuvioides represents a young C4 lineage with C4-like metabolism: CO2 compensation points range between C4 and C3–C4 intermediate values, and Rubisco was detected in bundle sheath and mesophyll.
A Revision of Sesuvium (Aizoaceae, Sesuvioideae)
2017
Sesuvium and Cypselea are closely related succulent genera within the Sesuvioideae (Aizoaceae). Since Cypselea is nested in Sesuvium in molecular studies and both genera share traits separating them from other members of the subfamily, we propose to include Cypselea in Sesuvium. Sesuvium (incl. Cypselea) comprises 14 species and is distributed worldwide with centres of diversity in southern Africa and North and Central America. Sesuvium comprises erect to procumbent herbs with opposite leaves that often bear conspicuous sheath-like lateral appendages on the petioles (pseudostipules). These and the many-seeded capsules are diagnostic traits, separating Sesuvium from the closely related gener…
Phylogeny of Sesuvioideae (Aizoaceae) – Biogeography, leaf anatomy and the evolution of C4 photosynthesis
2015
Abstract Sesuvioideae (Aizoaceae) form a small subfamily of drought-tolerant plants exhibiting leaf succulence, halophytic ecology, and the C4 photosynthetic pathway. Sesuvioideae are sister to the species-rich subfamilies Ruschioideae, Mesembryanthemoideae and Aizooideae that contain many CAM lineages. This close relationship of CAM and C4 taxa identifies the Sesuvioideae as an important clade to address hypotheses of photosynthetic pathway evolution. This study presents a molecular phylogeny of Sesuvioideae based on five markers (atpB-rbcL spacer, rps16 intron, trnL-trnF spacer, petB-petD spacer, ITS) and 51 accessions representing all genera and 37 species. We determined carbon isotope d…
