Preparations of heterocysts of Anabaena cylindrica Lemm. had 7- to 8-fold higher activities of glucose 6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase, 2-fold more hexokinase activity, and 0.02 to 0.06 times as much ribulose diphosphate carboxylase and glyceraldehyde 3-phosphate dehydrogenase activities as did whole filaments per milligram soluble protein in cell-free extracts. T...

The marine ascidian Clavelina cylindrica produces a series of interesting tricyclic quinolizidine and indolizidine alkaloids that show toxicity in a brine shrimp assay.1 Cylindricines A (1), C (2), D (3), E (4), and F (5) differ only in the functionality of the methylene substituent in the fivemembered ring. Interestingly, cylindricines A and B (7) interconvert simply upon standing in solution,...

This paper analyses relationships between relative growth rate (), seed mass, biomass allocation, photosynthetic rate and other plant traits as well as habitat factors (rainfall and altitude) in 20 wild species of Aegilops L. and one closely related species of Amblyopyrum (Jaub. & Spach) Eig., which differ in ploidy level (diploid, tetraploid and hexaploid). The plants were grown hydroponica...

Background and Aims Bread wheat (Triticum aestivum) has been through a severe genetic bottleneck as a result of its evolution and domestication. It is therefore essential that new sources of genetic variation are generated and utilized. This study aimed to generate genome-wide introgressed segments from Aegilops speltoides. Introgressions generated from this research will be made available for ...

genetic drift of germplasm in cultivated wheat is good motivation for studying genetic diversity in its wild relatives. in this study, r-rap, a new retrotransposon-based marker, was applied to assess the structure and genetic diversity of 30 accessions of aegilops sp. originating from different geographical regions of iran. the 15 r-rap primer combinations revealed a total of 338 bands ranging ...

Jointed goatgrass (Aegilops cylindrica Host) is an economically important weed in winter wheat (Triticum aestivum L.)–fallow production regions of the United States. Few options exist for management of jointed goatgrass in winter wheat due to the close genetic relationship between the two species. This research evaluated use of imazamox herbicide (2-[(RS)-4-isopropyl-4methyl-5-oxo-2-imidazolin-...

Objective: In traditional medicines, Imperata cylindrica (hereinafter referred to as I. cylindrica) roots are more frequently used than its leaves. The aim of this study was determine three parameters, namely the content total phenolic compounds, flavonoid content, and antioxidant activity leaves extracts. Then, root extract parameters were a comparison evaluate benefits herbal medicine.
