Leaf anatomy and subgeneric affiliations of C3 and C4 species of Suaeda (Chenopodiaceae) in North America

Abstract: The halophytic genus Suaeda (Chenopodiaceae) includes species with the C3 and C4 photosynthetic pathways. North American species of this genus were investigated to determine whether C3 and C4 leaf anatomy are consistent within the two sections of Suaeda, Chenopodina and Limbogermen, present on this continent. All species from section Chenopodina were found to possess C3 anatomy, whereas all species from section Limbogermen were found to be C4 species. Characteristics of leaf anatomy and chloroplast ultrastruct… Show more

“…The leaves had a single layer of epidermis, two or three layers of palisade tissue and inner water-storage tissue, containing vascular bundles. According to Fisher et al [6] the mesophyll of C 4 species of Suaeda is differentiated into three distinct layers: below the epidermis is palisade parenchyma, an inner chlorenchymatous sheath and central water-storage tissue. This specialized anatomy, so called suaedoid type, is typical for S. californica, S. taxiflora, S. moquinii, S. tampicensis and S. conferta.…”

“…Indeed, the evolution of such tissue in species with 'proto-Kranz anatomy' would be an extension of a frequently observed trend in certain plant lineages in which the species adapted to saline and drier climates have more strongly developed achlorophyllous, largecelled tissue. This tissue serves an apparent function for water storage either in the bundle sheath, mesophyll or hypodermal layers, and this trend of greater water storage with aridity is apparent within C 3 lineages with leaves [83,84] and phyllodes [85], but also within C 4 and CAM lineages [86,87] Evolution of the C 4 cycle (table 1, phase 3). The evolution of greater WUE is apparently an important step in C 4 evolution.…”

“…C 4 pathway is an adaptive mechanism to grow in stressful environment. These species grow abundantly in drier and more saline sites and persist throughout the dry season due to their succulence (Fisher et al, 1997). S. maritima is a C 3 species with austrobassioid leaf anatomy and colonizes all areas where perennial species are absent due to sensitivity to competitive interactions (Yeo and Flowers, 1980;Mateu Andres, 1989).…”
