Globally, C4 plants dominate hot, open environments, but this general pattern is underpinned by important differences in the biogeography of C4 lineages. In particular, the species richness of C4 Poaceae (grasses) increases strongly with increasing temperature, whereas that of the major C4 eudicot group Chenopodiaceae correlates positively with aridity. Freezing tolerance is a crucial determina...

The chemotaxonomic significance of ergastic substances that are aligned systematically to the Amaranthaceae-Chenopodiaceae group and their prospective applications, such as the use of its starch for food, health and industrial uses, were assessed in the present study employing species from four genera: Amaranthus (Amaranthaceae), Chenopodium, Atriplex and Suaeda (Chenopodiaceae). Alkaloids, fat...

RATES AND MODES OF SEQUENCE EVOLUTION IN VARIOUS LINEAGESWITHIN CHENOPODIACEAE

Choline monooxygenase (CMO) catalyzes the committing step in the synthesis of glycine betaine, an osmoprotectant accumulated by many plants in response to salinity and drought. To investigate how these stresses affect CMO expression, a spinach (Spinacia oleracea L., Chenopodiaceae) probe was used to isolate CMO cDNAs from sugar beet (Beta vulgaris L., Chenopodiaceae), a salt- and drought-tolera...

Aeolothrips zurstrasseni sp. n. is described from Fars Province, and A. modestus zur Strassen is newly recorded from Iran, in Isfahan Province. Both species have been collected from the flowers of Suaeda sp. (Chenopodiaceae), and the presence of several species of thrips on plants of this family is discussed. Recent records of Aeolothrips balati and A. citricinctus from Iran are not accepted here.

Haplothrips herajius sp. n. is described from leaves and flowers of a species of Suaeda in the south of Fars Province, Iran. This is the second Iranian species of Haplothrips with the unusual character state of extra setae on the metanotum. Information on variation in color and structure of the new species is provided. The similarities and host plant associations of this new species and Haploth...

Environmental conditions in coastal salt marsh habitats have led to the development of specialist genetic adaptations. We evaluated six DNA barcode loci of the 53 species of Poaceae and 15 species of Chenopodiaceae from China's coastal salt marsh area and inland area. Our results indicate that the optimum DNA barcode was ITS for coastal salt-tolerant Poaceae and matK for the Chenopodiaceae. Sam...
