Transcriptome analysis reveals major transcriptional changes during regrowth after mowing of red clover (Trifolium pratense)

Abstract Background Red clover ( Trifolium pratense ) is globally used as a fodder plant due its high nutritional value and soil improving qualities. In response to mowing, red exhibits specific morphological traits compensate the loss of biomass. The reaction well described, but underlying molecular mechanisms role for plants grown in field are unclear. Results Here, we characterize global transcriptional mowing by comparing under greenhouse conditions with growing on agriculturally fields. Unexpectedly, found that biotic abiotic stress related changes overlay their regrowth characterized transcription protein families involved these processes. Further, can show gibberellins, among other phytohormones, also contribute developmental processes after biomass-loss. Conclusions Our findings massive biomass triggers less than struggle stresses gibberellins play program clover. results provide first insights into physiological may serve base yield improvement.
