Transcriptome-wide mA methylation profile reveals tissue specific regulatory networks in switchgrass (Panicum virgatum L.) under cadmium stress.

The heavy metal cadmium (Cd), known for its high toxicity, poses a grave threat to human health through the food chain. N-methyladenosine (mA), the most abundant internal modification, regulates plant adaptation to various adversities, yet the panorama of mA modifications in switchgrass under cadmium stress remains elusive. This study examines the physiological responses of switchgrass roots and shoots exposed to 50 μM CdCl, alongside an overview of transcriptome-wide mA methylation patterns.

Characterization of the mA gene family in switchgrass and functional analysis of PvALKBH10 during flowering.

N-methyladenosine (mA), a nucleotide modification that is frequently seen in RNA, plays a crucial role in plant growth, development and stress resistance. However, the mA regulatory machinery in switchgrass (Panicum virgatum L.), a model plant for cellulose-to-ethanol conversion, remains largely unknown.

Increases Biomass Yield and Enhances Alkaline Tolerance in Switchgrass ( L.).

Switchgrass is an important bioenergy crop valued for its biomass yield and abiotic tolerance. Alkali stress is a major abiotic stress that significantly impedes plant growth and yield due to high salinity and pH; however, the response mechanism of switchgrass to alkali stress remains limited. Here, we characterized , an ARF-like gene, which was up-regulated in both the shoot and root tissues under alkali stress conditions.

N-methyladenosine analysis unveils key mechanisms underlying long-term salt stress tolerance in switchgrass (Panicum virgatum).

N-methyladenosine (mA) RNA modification is critical for plant growth, development, and environmental stress response. While short-term stress impacts on mA are well-documented, the consequences of prolonged stress remain underexplored. This study conducts a thorough transcriptome-wide analysis of mA modifications following 28-day exposure to 200 mM NaCl.
