Reference gene selection for molecular studies of dormancy in wild oat (Avena fatua L.) caryopses by RT-qPCR method
Molecular studies of primary and secondary dormancy in Avena fatua L., a serious weed of cereal and other crops, are intended to reveal the species-specific details of underlying molecular mechanisms which in turn may be useable in weed management. Among others, quantitative real-time PCR (RT-qPCR) data of comparative gene expression analysis may give some insight into the involvement of partic...
متن کاملRespiration and Protein Synthesis in Dormant and After-ripened Seeds of Avena fatua.
Dormant seeds of Avena fatua, which do not germinate when allowed to imbibe water, have a respiration rate only about 20% less than that of imbibed nondormant (after-ripened) seeds in the period before actual germination and are capable of synthesizing protein at a rate comparable to that of the nondormant seeds. An increase of protein synthesis is observed in nondormant seeds at the beginning ...
متن کاملParticipation of the tightly-bound (putative cytoskeleton-bound) polysomes in translation during germination of dormant and non-dormant cereal caryopses.
Research was done on dormant and non-dormant barley cv. Ars caryopses and triticale cv. Grado caryopses treated and non-treated with abscisic acid (ABA). During germination higher participation of populations of so-called tightly-bound polysomes (TBP) in embryos of dormant barley caryopses was observed, as well as their high metabolic activity. In embryos of triticale caryopses of which dormanc...
متن کاملInhibitory Effect of Hydroalcoholic Extracts of Caltrop (Tribulus terrestris L.) on Germination and Growth of Avena fatua L., Chenopodium album L., Setaria viridis L. and Amaranthus retroflexus L.
Background: The use of allelopathic plant extracts as herbicide is being popularized in recent years. Objective: This research has been conducted to evaluate the allelopathic potential of caltrop (Tribulus terrestris L.) on seed germination and growth of Avena fatua L., Chenopodium album L., Setaria viridis L. and Amaranthus retroflexus L. Methods: This research was done to evalature the ef...
