A new plant virus, named Mentha arvensis robigovirus 1 (MARV1), was discovered using genomic sequencing. MARV1 belongs to the Robigovirus genus and is closely related to African oil palm ringspot virus. This finding provides important information about a previously unknown plant virus.
DNA methylation in the promoter region of genes increases during flower senescence in carnation. DcROS1 gene is involved, and its overexpression delays senescence. Amino acid biosynthesis genes affected by DNA methylation influence flower senescence. DcROS1 plays a role in DNA methylation and amino acid biosynthesis during flower senescence.
Scientists have identified and studied 37 glutamate receptor (GLR) genes in sweet potato, discovering that they play a crucial role in plant development, response to stress, and other important functions. The study provides valuable insights for future research and breeding in sweet potatoes.
Sugarcane top extract activates mitochondrial energy metabolism and increases PGC-1α levels in muscle and liver cells. This may have positive effects on tissue health and could have nutraceutical applications.
Researchers found that a specific RNA called SUF plays a key role in determining the sex of Marchantia polymorpha plants. They discovered that when SUF is present, the plant develops as male, but by inserting a sequence into SUF, the plant can develop as female. The study highlights the importance of SUF transcription in controlling sex differentiation in M. polymorpha.
The researchers sequenced the complete chloroplast genome of a traditional Chinese medicinal plant. This data will help understand the plant's evolutionary patterns and aid further research in its systematics.
Infection of winter barley roots by Barley Yellow Mosaic Virus (BaYMV) causes yield losses. Resistance genes (rym1-rym15, unknown) target virus replication. These genes determine immunity, partial immunity, or susceptibility to BaYMV. Understanding this can aid in breeding resistant barley varieties.
Researchers developed a method to identify gene family members in poorly assembled genomes using the P-type ATPase superfamily as an example. They successfully identified members in high-quality genomes and tested the hypothesis that the number of P-type ATPase genes correlates with a plant's ability to tolerate saline conditions.
