Molecular dissection of the parental contribution in Paeonia Itoh hybrids.

Hybrid breeding between herbaceous peonies (the maternal parent) and tree peonies (the paternal parent) results in Paeonia Itoh hybrids (Itoh peonies), a triploid species that combines advantageous traits from both parental species, thus offering great economic value. However, the exact genetic contribution of the two parents is unclear. In this study, we introduce a straightforward approach utilizing heterozygous single-nucleotide polymorphisms (SNPs) and Sanger sequencing of targeted gene fragments to trace the original bases back to their parents in Itoh peonies.

mA demethylase OsALKBH5 is required for double-strand break formation and repair by affecting mRNA stability in rice meiosis.

N-methyladenosine (mA) RNA modification is the most prevalent messenger RNA (mRNA) modification in eukaryotes and plays critical roles in the regulation of gene expression. mA is a reversible RNA modification that is deposited by methyltransferases (writers) and removed by demethylases (erasers). The function of mA erasers in plants is highly diversified and their roles in cereal crops, especially in reproductive development essential for crop yield, are largely unknown.

Evolution and Functional Differentiation of the C-terminal Motifs of FtsZs During Plant Evolution.

Filamentous temperature-sensitive Z (FtsZ) is a tubulin-like GTPase that is highly conserved in bacteria and plants. It polymerizes into a ring at the division site of bacteria and chloroplasts and serves as the scaffold protein of the division complex. While a single FtsZ is present in bacteria and cyanobacteria, there are two subfamilies, FtsZ1 and FtsZ2 in the green lineage, and FtsZA and FtsZB in red algae.
