Comparison of common cytotypesof Andropogon gerardii(Andropogoneae, Poaceae).
Many plant species contain populations with more than one polyploid cytotype, but little is known of the mechanisms maintaining several cytotypes in a population. Andropogon gerardii cytotypes were compared to evaluate different models of autopolyploid cytotype coexistence. The enneaploid (90 chromosome, 9x) cytotype was found to be larger and taller than the hexaploid (60 chromosome, 6x) cytot...
متن کاملMolecular evolution of FLORICAULA/LEAFY orthologs in the Andropogoneae (Poaceae).
Members of the grass family (Poaceae) exhibit a broad range of inflorescence structures and other morphologies, making the grasses an interesting model system for studying the evolution of development. Here we present an analysis of the molecular evolution of FLORICAULA/LEAFY-like genes, which are important developmental regulatory loci known to affect inflorescence development in a wide range ...
متن کاملKaryotypic characteristics of Cenchrus longispinus (Hack.) Fernald (Poaceae)
Cenchrus longispinus (Hack.) Fernald (Poaceae), as a weed, is native of America, but has also been introduced in other countries including Iran in the recent years. In this study, karyotypic features in one population of this species was studied. As such, microscopic slides of root tip meristem cells were prepared using the classical squash technique and aceto-iron-hematoxylene staining. The ch...
متن کاملPHYLLOCHRON OF Paspalum notatum FL. AND Coelorhachis selloana (HACK.) CAMUS IN NATURAL PASTURE
Leaf appearance rate and phyllochron are related variables which play a central role in forage production. Phyllochron is the time interval between the appearance of successive leaves and varies according to a number of environmental factors, among which temperature is the most important. The experiment was conducted in natural pasture with the aim of testing phyllochron variation under differe...
