astragalus kurdaicus saposhn. ex sumn is now considered as an additional species of the flora of iran. this species was introduced from middle asia, and is also recorded from ne iran. it belongs to astragalus section cystium.

nowadays, in many rangelands, due to over grazing, and problems that some plantshave in germination, the rate of forage production is greatly reduced. so to take advantages ofthe benefits of such plants, it is necessary to identify and remove barriers of germination andestablishment of suitable plants. the present study was designed to investigate differenttreatments of breaking dormancy and st...

Data format: BayesPref requires that data be provided as an object class matrix. The data provided in "YGGVdata" is oviposition preference data for Lycaeides populations from Yuba Gap, CA and Gardnerville, NV. Here, the populations have been coded numerically. That is, Yuba Gap is population 1 and Gardnerville is population 2. The abbreviations for plant species are as follows: Ast, Astragalus ...

Background: The objective of this study was to determine the distribution some endemic species genus Astragalus L. (Astragalus anthylloides Lam., lycius Boiss. and xylobasis var. angustus (Freyn & Sint.) Freyn Bornm.) species, interaction between soil, climatic characteristics desertification risk which affect these in semi-arid environment Çankırı, northwest Turkey. During vegetation period 20...

An ultrasensitive bioassay system for the detection of N-acylhomoserine lactones (AHLs) was constructed in Agrobacterium tumefaciens by using the T7 expression system to overproduce the AHL receptor TraR. This strain detected many diverse AHLs, some at extremely low concentrations. We used this strain to detect for the first time AHLs made by Mesorhizobium huakuii, which symbiotically fixes nit...
