In Arabidopsis (Arabidopsis thaliana) the low-temperature induction of genes encoding the C-REPEAT BINDING FACTOR (CBF) transcriptional activators is a key step in cold acclimation. CBFs in turn activate a battery of downstream genes known as the CBF regulon, which collectively act to increase tolerance to low temperatures. Fundamental questions are: What determines the size and scope of the CB...
The present work was planned to evaluate the phytoextraction of metal mine tailings, Sarcheshmeh copper mine, SE of Iran, by the endemic plant species Medicago sativa L. (Alfalfa). In this pot experiment, we investigated the effects of seven amendments on the growth of alfalfa and uptaking metals from the mine tailings and stream sediment of tailing dam surface. The mean metal concentrations in...
At the 2nd Medicago meeting (a satellite of the 1999 IS-MPMI meeting in Amsterdam), investigators perceived a need for standardization of genetic nomenclature in Medicago truncatula, due to the rapid growth of research on this species in the past few years. Establishment of such standards grew out of discussions begun at this meeting and continued electronically throughout the M. truncatula com...
Aux/IAA genes play a pivotal role in auxin transcriptional regulation. Their functions were mainly studied in Arabidopsis through analysis of gain-of-function mutants. In the tomato, the Solanaceae reference species, different studies on Sl-IAA down-regulated lines showed specific role for Sl-IAA genes. Our recent work revealed that the Sl-IAA 27 gene displays a distinct behavior compared with ...
Legumes played central roles in the development of agriculture and civilization, and today account for approximately one-third of the world's primary crop production. Unfortunately, most cultivated legumes are poor model systems for genomic research. Therefore, Medicago truncatula, which has a relatively small diploid genome, has been adopted as a model species for legume genomics. To enhance i...
The rumen bacterial strains Butyrivibrio fibrisolvens Hl7c, Fibrobacter succinogenes S8S, Lachnospira multiparus 4°, Ruminococcus albus 7 and R. flavefaciens FD-l were compared individually and as a five-species mixture with a rumen inoculum for their ability to degrade lucerne (Medicago sativa L.) stem cell wall polysaccharides. Two maturity stages oflucerne (bud and full flower) were utilized...
The proportion of starch, protein and oil in legume seeds is species dependent. The model legume, Medicago truncatula, has predominantly oil and protein stores. To investigate the regulation of seed oil production we compared M. truncatula with M. orbicularis, which has less oil and protein. The types of protein and fatty acids are similar between the two species. Electron microscopy indicated ...
Leptochloa chinensis (L.) Nees, is known as a noxious weed species in upland and lowland crop cultivation, has naturalized many countries an invasive plant species. In this study, the allelopathic characteristic of L. was evaluated to understand its invasiveness. An aqueous methanol extract above-grand parts suppressed growth species; Echinochloa crus-galli Beauv., Vulpia myuros C. Gmel. Lolium...
The article presents the results of primary introduction experience rare species Fabaceae family flora Republic Bashkortostan (the RB), included in Red Data Book Russian Federation (2008). study these was carried out Botanical Garden Ufa. Under cultivation conditions, 5 were tested: еndemic Middle and Southern Urals Astragalus clerceanus Iljin et Krasch., Hedysarum grandiflorum Pall., Volga-Sou...
Nitric oxide (NO) is a bioactive molecule involved in numerous biological events that has been reported to display both pro-oxidant and antioxidant properties in plants. Several reports exist which demonstrate the protective action of sodium nitroprusside (SNP), a widely used NO donor, which acts as a signal molecule in plants responsible for the expression regulation of many antioxidant enzyme...
