MetabolomicsMetabolo-transcriptomics analyses reveal alfalfa adaptation to combined saline-alkali and low-temperature stress in the field

Metabolomics analysis revealed specific accumulation of amino acids, organic acids, carbohydrates, fatty acids and flavonoids in ZD compared with that in BM. The core differential metabolites associated with ZD stress resistance included isoleucine, fumaric acid, raffinose and isovitexin. In...

MetabolomicsMetabolomic analysis of alfalfa (Medicago sativa L.) root-symbiotic rhizobia responses under alkali stress
Alkaline salts (e.g., NaHCO3 and Na2CO3) causes more severe morphological and physiological damage to plants than neutral salts (e.g., NaCl and Na2SO4) due to differences in pH. The mechanism by which plants respond to alkali stress is not fully understood, especially in plants having symbotic relat...

MetabolomicsABA accumulation confers cross-adaptation to saline-alkali and cold stresses in alfalfa

Combined saline-alkali and cold stresses severely constrain plant growth at middle and high latitudes. Plants have evolved cross-adaptation mechanisms wherein exposure to one stress enhances resistance to another. However, the specific mechanisms driving cross-adaptation between saline-alkali and...

MetabolomicsMulti-omics and physiological analysis reveal the involvement of secondary metabolism and carbohydrate in drought regulation in alfalfa
Metabolite differential analysis indicates that genes involved in pathways such as secondary metabolism, carbohydrate, phenylpropanoid biosynthesis and flavonoid biosynthesis may regulate drought adaptation in alfalfa.

TranscriptomicsUsing RNA-Seq for gene identification, polymorphism detection and transcript profiling in two alfalfa genotypes with divergent cell wall composition in stems
Alfalfa, [Medicago sativa (L.) sativa], a widely-grown perennial forage has potential for development as a cellulosic ethanol feedstock. The application of genomic approaches would advance development of alfalfa as a cellulosic feedstock. However, the genomics of alfalfa, a non-model species, is sti...

ProteomicsQuantitative proteomic analysis of the role of miRNA156 in alfalfa under drought stress
Alfalfa is the most produced perennial forage crop in Canada. Drought stress is a major form of abiotic stress, affecting its productivity and annual yield. A small RNA, miR156, plays a major role in drought tolerance by downregulating downstream SPL genes, but its effects at the proteome level are ...

TranscriptomicsSystem responses to long-term drought and re-watering of two contrasting alfalfa varieties
Two alfalfa varieties, 'Chilean' (M. sativa ssp. sativa var. Chilean, drought sensitive) and 'Wisfal' (M. sativa ssp. falcata var. Wisfal, drought tolerant), with contrasting water use efficiency were subjected to water withholding for 11 days followed by re-watering. Samples were taken for well-wa...

ProteomicsComparative Transcriptome Combined with Proteome Analyses Revealed Key Factors Involved in Alfalfa (Medicago sativa) Response to Waterlogging Stress
Alfalfa (Medicago sativa) is the most widely grown and most important forage crop in the world. However, alfalfa is susceptible to waterlogging stress, which is the major constraint for its cultivation area and crop production. So far, the molecular mechanism of alfalfa response to the waterlogging ...

Two alfalfa varieties contrasting in heat tolerance, MS30 and MS37, were used for this experiment, and their seeds were provided by Sichuan Academy of Grassland Sciences. After two months of growth, both alfalfa varieties grow into adult-plants. Select 10-15 healthy plants with consistent growth to ...

TranscriptomicsTranscript analysis in two alfalfa salt tolerance selected breeding populations relative to a non-tolerant population
With the growing limitations on arable land, alfalfa (a widely cultivated, low-input forage) is now being selected to extend cultivation into saline lands for low-cost biofeedstock purposes. Here, minerals and transcriptome profiles were compared between two new salinity-tolerant North American alfa...
