Analysis of occasionally occurring peloric Iberis flower variants and comparative functional studies of TCP homologs in Arabidopsis demonstrate the importance of an altered temporal IaTCP1 expression within the Brassicaceae to govern the formation of a monosymmetric corolla.

The results show that the ROXY1 protein functions in the nucleus, likely by modifying PAN posttranslationally and thereby regulating its activity in petal primordia initiation, and affects later petal morphogenesis, probably by modulating other TGA factors that might act redundantly during differentiation of second whorl organs.
Genome of the Asian longhorned beetle (Anoplophora glabripennis), a globally significant invasive species, reveals key functional and evolutionary innovations at the beetle–plant interface
Amplification and functional divergence of genes associated with specialized feeding on plants, including genes originally obtained via horizontal gene transfer from fungi and bacteria, contributed to the addition, expansion, and enhancement of the metabolic repertoire of the Asian longhorned beetle and to a lesser degree, other phytophagous insects.

EcFLO, a FLORICAULA-like gene from Eschscholzia californica is expressed during organogenesis at the vegetative shoot apex
It is shown that EcFLO mRNA is expressed during the vegetative phase of the shoot apical meristem and in developing dissected leaves in a characteristic manner, compared to that of other eudicots and discussed in terms of evolution of FLORICAULA expression and function.

This study emphasizes the potential of regulatory changes in the evolution of morphological novelties, like corolla monosymmetry in the Brassicaceae, through a heterochronic CYC2 expression shift from an ancestral early adaxial expression in floral meristems to anadaxial CYC 2 transcript accumulation later in petal development.

The data indicate that CpeS is specific for 3Z-PEB transfer to βCys82 of phycoerythrin and essential for the correct configuration of the attachment product.

It is shown that PebS acts via a substrate radical mechanism and that two conserved aspartate residues at position 105 and 206 are critical for stereospecific substrate protonation and conversion.
