A comparative study of the lipid bilayer phase status and structure of the outer membrane of free-livingBradyrhizobiumstrain 359a (Nod+Fix+) and 400 (Nod+FixL) orRhizobium leguminosarum97 (Nod+Fix+, effective) and 87 (Nod+FixL, ineffective) has been carried out. Also, the effect of the symbiotic pair combination on the lipid bilayer structure of the bacteroid outer membrane and peribacteroid membrane, isolated from the nodules ofLupinus luteusL. orVicia fabaL., has been studied. As a result, it is shown that the lipid bilayer status of the bacteroid outer membrane is mainly determined by microsymbiont, but not the host plant. In the contrast, the lipid bilayer status of the peribacteroid membrane and, as a consequence, its properties depend on interaction of both symbiotic partners.

Quantification of the flavonoids in yellow lupin (Lupinus luteus; Leguminosae) seedlings revealed that a flavone glucoside, 7-O-β-(2-O-β-rhamnosyl)glucosyl-4′,5,7-trihydroxyflavone (apigenine 7-O-β-neohesperidoside), is rich in the epicotyl and cotyledon. In hypocotyls and roots, 8-C-β-glucosyl-4′,5,7-trihydroxyisoflavone (genistein 8-C-β-glucoside) was a predominant flavonoid constituent. The roles of the localized flavonoids are briefly discussed relating to defense against biotic and abiotic external stresses.

Background: This study was conducted to determine the effects of microbial fertilizer and vermicompost applications on the yield and yield related parameters of broad beans (Vicia faba L.) under zero chemical fertilizer applied conditions. Trial area was a highland remote to sea under Mediterranean climate in South Eastern Anatolia of Turkey. It is located in fertile crescent and 180 km away to Karacadag Mountains (Diyarbakir) where Einkorn wheat (Aegilops monococcum L.) was first cultivated in history approximately ten thousand years ago. The broad bean was also among the founder crops of the Near East including the trial location. Methods: Rhizobium leguminosarum inoculant were used as microbial fertilizer in the experiments. Applied vermicompost doses were 0, 400, 800 and 1200 kg ha-1. The trials was conducted for two years and replicated thrice in a randomized block deign. Conclusion: Application of vermicompost was found significantly effective on the plant height, first pod height, number of pods per plant, number of seeds per pod, 100 grain weight and grain yield. Aapplication of 800 kg ha-1 and 120 kg ha-1 vermicompost along with Rhizobium leguminosarum inoculation was found superior for grain yield.
