Ensifer meliloti strain RRI128 is an aerobic, motile, Gram-negative, non-spore-forming rod. RRI128 was isolated from a nodule recovered from the roots of barrel medic (Medicago truncatula) grown in the greenhouse and inoculated with soil collected from Victoria, Australia. The strain is used in commercial inoculants in Australia. RRI128 nodulates and forms an effective symbiosis with a diverse ...
Legumes have the unique ability to host nitrogen-fixing Rhizobium bacteria as symbiosomes inside root nodule cells. To get insight into this key process, which forms the heart of the endosymbiosis, we isolated specific cells/tissues at different stages of symbiosome formation from nodules of the model legume Medicago truncatula using laser-capture microdissection. Next, we determined their asso...
Alfalfa is a good green manure source, but its effect on rice growth has not been fully elucidated. Two green manure species, alfalfa and broad bean (Vicia faba L.), and two N fertilizer levels, alone or combination, were applied to a rice field. The results indicated that alfalfa had more pronounced effects on increasing soil labile phosphorus (P) fractions (including NaHCO3-Pi, NaOH-Pi), P up...
Five alfalfa (Medicago sativa L) cultivars from different areas of Iran were evaluated for oxidative markers under salinity conditions. Plants were grown in hydroponic condition by Hoagland nutrient solution containing different amounts of NaCl (control, 50 and 100 mM). Relative growth rate, membrane stability, lipid peroxidation, proline, hydrogen peroxide and relative water contents were dete...
برای بررسی تنوع ژنتیکی جمعیت های وحشی ایرانی یونجه (medicago sativa l.) و تعیین ارتباط آن با عوامل اکولوژیکی، الگوی پروتئینی 210 ژنوتیپ از 21 جمعیت بذری یونجه موجود در بانک ژن منابع طبیعی بررسی شد. کلیه مراحل تحقیق در سال 1389 در گلخانه تحقیقاتی و آزمایشگاه ارزیابی ملکولی بانک ژن موسسه تحقیقات جنگلها و مراتع انجام شد. بر اساس نتایج sds-page، 44 باند قابل تکثیر، پپتید پروتئینی، برای مطالعه تنوع ...
This study was performed on an alfalfa crop located on the central plain of La Araucanía Region, Chile and in the Laboratorio de Entomología Aplicada de la Facultad de Ciencias Agropecuarias y Forestales at the Universidad de La Frontera. Certain aspects of the biology of Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) were determined, more specifically in relation to its life cycle, s...
for comparison of the food value of four different epecies of aquatic weeds: potamogeton pectinatus , potamogeton lucens, potamogeton perfoliatus, najas minor and two species of terrestrial grass: medicago sativa and cynodon dactylon by grass carp (ctenopharyngodon ideda), was studied in the shahicl rejai fishfarm in sari (province of mazandaran). totally 6 concrete ponds with 30 cubic meter vo...
