An interdisciplinary research strategy to improve symbiotic nitrogen fixation and yield of common bean (Phaseolus vulgaris) in salinised areas of the Mediterranean basin.
The main findings of a cooperative research group of agronomists, plant breeders, microbiologists, physiologists and molecularists to improve the symbiotic nitrogen fixation (SNF) and N2-dependent yield of common bean under moderate salinity in the Mediterranean basin are summarised. Agronomic surveys in reference production areas show large spatial and temporal variations in plant nodulation a...
متن کاملMovement of rhizobia inside tobacco and lifestyle alternation from endophytes to free-living rhizobia on leaves.
Rhizobia are well-known for their ability to infect and nodulate legume roots, forming a nitrogen-fixing symbiosis of agricultural importance. In addition, recent studies have shown that rhizobia can colonize roots and aerial plant tissues of rice as a model plant of the Graminaceae family. Here we show that rhizobia can invade tobacco, a model plant belonging to the Solanaceae family. Inoculat...
متن کاملThe Legume-rhizobia Symbiosis under Salt Stress - a Review
Salinity is one of the severe problems in worldwide agricultural production. Soil salinity limits the productions of both forage and grain legumes. Adverse effects of salinity are mediated through detrimental effects on the rhizobium legume interactions that lead to the establishment of the nitrogen fixing symbiosis. Salt stress inhibits the initial steps of the rhizobia legume symbiosis. For i...
متن کاملSelection of plant growth-promoting bacteria in sweet sorghum (Sorghum bicolor (L.) Moench) under the effects of salinity
Background Sorghum, a grassy non-halophyte, it is both drought and salinity tolerant, and is considered a promising crop for semiarid regions. During the last 20 years, its culture has expanded in Brazilian production by 780%, reaching 1,928,970 tons in 2009 [1]. Salinization of the soil and lack of rain are increasing constraints in semiarid regions. They predominate in northeastern Brazil. Th...
متن کاملMetagenome analysis of the root endophytic microbial community of Indian rice (O. sativa L.)
This study reports the root endophytic microbial community profile in rice (Oryza sativa L.), the largest food crop of Asia, using 16S rRNA gene amplicon sequencing. Metagenome of OS01 and OS04 consisted of 11,17,900 sequences with 300 Mbp size and average 55.6% G + C content. Data of this study are available at NCBI Bioproject (PRJNA360379). The taxonomic analysis of 843 OTU's showed that the ...
