Motivation: Transcription factors (TFs) are DNA-binding proteins that regulate gene expression. Traditional methods predict a protein as a TF if the protein contains any DNA-binding domains (DBDs) of known TFs. However, this approach fails to identify a novel TF that does not contain any known DBDs.

The evolutionary conservation of type III polyketide synthases (PKS) in Selaginella has been elucidated, and the critical amino acid residues of the anther-specific chalcone synthase-like enzyme (SmASCL) have been identified. Selaginella species are the oldest known vascular plants and a valuable resource for the study of metabolic evolution in land plants. Polyketides, especially flavonoids and sporopollenin precursors, are essential prerequisites for plant land colonization.

Remodelling regulatory pathways to directionally increase the efficiency of specific promoters in chassis cells is an effective strategy for the rational construction of expression systems. However, the repeated utilization of one regulator to modify the host cell to improve expression motif efficiency has a limited effect. Therefore, it is preferable to identify new regulatory factors to activate specific pathways and thus further improve the efficiency of target elements.

Transitions across ecological boundaries, such as those separating freshwater from the sea, are major drivers of phenotypic innovation and biodiversity. Despite their importance to evolutionary history, we know little about the mechanisms by which such transitions are accomplished. To help shed light on these mechanisms, we generated the first high-quality, near-complete assembly and annotation of the genome of the American shad (Alosa sapidissima), an ancestrally diadromous (migratory between salinities) fish in the order Clupeiformes of major cultural and historical significance.

Pollination by insects is vital for global agriculture, with honey bees (Apis mellifera L.) being the most important pollinators. Honey bees are exposed to numerous stressors, including disease, pesticides, and inadequate nutrition, resulting in significant colony losses.
