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.

ProteomicsInvestigating the role of miR156 network in abiotic stress tolerance in alfalfa
Heat stress and extreme temperatures negatively affect plant development by disrupting regular cellular and biochemical functions, ultimately leading to reduced crop production. Recently, our group has shown through physiological experiments that miR156 overexpression resulted in an improved 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...
