The LEED..PEED (LP) gene family in Medicago truncatula (A17) is composed of 13 genes coding small putatively secreted peptides with one to two conserved domains of negatively charged residues. This family is not present in the genomes of Glycine max, Lotus japonicus, or the IRLC species Cicer arietinum. LP genes were also not detected in a Trifolium pratense draft genome or Pisum sativum nodule...
In the Rhizobium-legume symbiosis, compatible bacteria and host plants interact through an exchange of signals: Host compounds promote the expression of bacterial biosynthetic nod (nodulation) genes leading to the production of a lipochito-oligosaccharide signal, the Nod factor (NF). The particular array of nod genes carried by a given species of Rhizobium determines the NF structure synthesize...
The barley grasses (Hordeum glaucum Steud. and Hordeum leporinum Link.) are important weeds of crops and pastures in South Australia. Populations of both species have evolved resistance to paraquat, primarily following intensive use of paraquat for winter weed control in lucerne (Medicago sativa L.) crops. In the past few years, agricultural consultants have been reporting an increase in proble...
یونجه یک ساله یکی از مهم ترین گیاهان علوفه ای جهان به شمار می رود. به منظور بررسی اثر غلظت های مختلف شوری بر جوانه زنی و رشد گونه های medicago scutellata، medicago polymorpha، medicag truncatula و medicago rigidula، آزمایشاتی به صورت فاکتوریل در قالب کاملاً تصادفی در چهار تکرار با شش سطح شوری (صفر، 5، 10، 15، 20 و 25 دسی زیمنس بر متر) انجام شد. ویژگی های سرعت جوانه زنی، درصد جوانه زنی، طول ساقه...
The establishment of the legume-rhizobia symbiosis between Medicago spp. and Sinorhizobium meliloti is dependent on the production of sulfated lipo-chitooligosaccharidic nodulation (Nod) factors by the bacterial partner. In this article, using a biochemical approach to characterize putative Nod factor receptors in the plant host, we describe a high-affinity binding site (Kd = 0.45 nm) for the m...
جهت انتخاب یونجه های یکساله پرمحصول برای کشت پاییزه در منطقه دشت گرگان سه گونه یونجه یکساله خارجی شامل mdicago scutellata ، medicago truncatula، medicago littoralis و دوگونه یونجه بومی medicago orbicularis و medicago polymorpha در قالب طرح آماری بلوکهای کامل تصادفی با چهار تکرار برای مدت سه سال در ایستگاه عراقی محله گرگان مورد بررسی قرار گرفتند. نتایج حاصل نشان داد که بسته به نوسان عوامل اقلیم...
The present paper was a part of Ph.D research work, conducted during the year 2014, in which 87 poisonous plants belonging to 54 genera, were collected, documented and preserved in the herbarium of Bannu, Department of Botany UST, Bannu Khyber Pakhtunkwa Pakistan. The plants were identified botanically, arranged alphabetically along with their Latin name, family name, common name, poisonous par...
The novel food ingredient, alfalfa protein concentrate (APC), consists of a complex of protein (45-60 %), minerals (Ca, Fe, Mg), and vitamins (A, D, E, K). APC is extracted from lucerne (Medicago sativa spp. sativa) also known as alfalfa. Alfalfa is processed to first provide a press juice from which the proteins associated with carotenoid and chlorophyll pigments are separated by heat treatmen...
