Other claims from this paper (14)
- Intervention effect Foliar spraying with 500 mg/kg Se significantly reduced alfalfa biomass.
- Intervention effect Excessive Se increased alfalfa H2O2 content by 14.2%.
- Intervention effect Excessive Se increased alfalfa MDA content by 4.3%.
- Observation Leaf ultrastructure damage in alfalfa revealed phytotoxic effects of Se.
- Intervention effect At 500 mg/kg Se alfalfa synthesized more S-type lignin, probably to increase Se tolerance.
- Intervention effect At 500 mg/kg Se alfalfa had lower nutritional quality.
- Observation RNA-seq found 2112 Se-responsive differentially expressed genes in alfalfa.
- Intervention effect Se treatment up-regulated 1322 mRNAs in alfalfa.
- Intervention effect Se treatment down-regulated 790 mRNAs in alfalfa.
- Observation Alfalfa had 296 known miRNAs.
- Observation Alfalfa had 258 conserved miRNAs.
- Observation Alfalfa had 310 novel miRNAs, predicted by analysis.
- Intervention effect Se induced 77 differentially expressed miRNAs in alfalfa.
- Mechanism miRNAs play a crucial role in forming Se tolerance in alfalfa through regulation of redox, chlorophyll degradation, photosynthesis and cell wall synthesis target genes.
