BURP domain-containing proteins belong to a newly identified protein class that is unique to plants and plays an important role in plant development and metabolism. Although systematic characterization of BURP domain-containing proteins have been carried out in many species, such as rice, poplar and maize, little is known about BURP domain-containing proteins in Medicago. In this study, multipl...
Plants experience various environmental stresses, but tolerance to these adverse conditions is a very complex phenomenon. The present research aimed to evaluate a set of genes involved in osmotic response, comparing soybean and medicago with the well-described Arabidopsis thaliana model plant. Based on 103 Arabidopsis proteins from 27 categories of osmotic stress response, comparative analyses ...
Next-generation sequencing technology has increased the capacity to generate molecular data for plant biological research, including phylogenetics, and can potentially contribute to resolving complex phylogenetic problems. The evolutionary history of Medicago L. (Leguminosae: Trifoliae) remains unresolved due to incongruence between published phylogenies. Identification of the processes causing...
Six Medicago species were investigated to characterize and valorize plant genetic resources of pastoral interest in Morocco. Samples were obtained from the core collection of the South Australian Research and Development Institute (SARDI). The transferability of single sequence repeat markers of Medicago truncatula was successful with 97.6% efficiency across the five species. A total of 283 all...
Legumes (Fabaceae, Leguminosae) are unique in their ability to carry out an elaborate endosymbiotic nitrogen fixation process with rhizobia proteobacteria. The symbiotic nitrogen fixation enables the host plants to grow almost independently of any other nitrogen source. Establishment of symbiosis requires adaptations of the host cellular metabolism, here foremost of the energy metabolism mainly...
Genome sequencing of the model legumes, Medicago truncatula and Lotus japonicus, provides an opportunity for large-scale sequence-based comparison of two genomes in the same plant family. Here we report synteny comparisons between these species, including details about chromosome relationships, large-scale synteny blocks, microsynteny within blocks, and genome regions lacking clear corresponden...
Wild populations of Medicago ciliaris and Medicago polymorpha were subjected to four salt treatments 0, 50, 100 and 150 mM NaCl, plant growth and proline concentration in leaves were assessed. The analyzed data revealed significant variability in salt response within and between the two species, depending on the salinity level. It was found that high NaCl concentrations affected all the growth ...
در قالب طرح بررسی زنگ های گیاهان تیره fabaceae و بر اساس مطالعه نمونه های هرباریومی و جدید جمع آوری شده گونه های زراعی و غیر زراعی یونجه و شبدر آلوده به زنگ، شش گونه uromycesبه عنوان عوامل ایجادکننده زنگ روی جنس های مذکور در ایران شناسایی و تشریح می گردند. گونه u. fallens به عنوان عضو جدیدی برای فلور زنگ های ایران معرفی می شود. گونه u. striatus به عنوان عامل اصلی زنگ روی medicago sativa و گونه...
پراکنش زیستی جنس یونجه در ایران مطالعه گردید. پراکنش گونه های چند ساله m. sativa و m. lupulina عمدتا منطبق با نواحی کوهستانی ایران است. از بین دیگر گونه های این جنس، پراکنش m. rigidula بیشترین شباهت را با گونه های قبلی در مناطق کوهستانی دارد. اغلب گونه های یونجه در مناطقی با شرایط آب و هوایی مدیترانه ای رویش دارند. مطابق این تحقیق، یک مرکز اصلی و دو مرکز فرعی تنوع زیستی برای این جنس در ایرا...
ABSTRACT- Annual Medicago species (Medicago spp.) are native to the Mediterranean region and widely used in fields and pastures in Iran. There are several methods of sowing annual Medicago species, each with different effects on the performance. However, there is currently no sufficient information about the appropriate methods for sowing Medicago species. In order to evaluate methods of sowing...
