Molecular evolution and diversification of phytoene synthase (PSY) gene family

Genetics and Molecular Biology, 2022
Phytoene synthase (PSY) is a crucial enzyme required for carotenoid biosynthesis, encoded by a gene family conserved in carotenoid-producing organisms. This gene family is diversified in angiosperms through distinct duplication events.

INDEPENDENT ORIGINATION OF FLORAL ZYGOMORPHY, A PREDICTED ADAPTIVE RESPONSE TO POLLINATORS: DEVELOPMENTAL AND GENETIC MECHANISMS [PDF]

, 2016
Observations of floral development indicate that floral organ initiation in pentapetalous flowers more commonly results in a medially positioned abaxial petal (MAB) than in a medially positioned adaxial petal (MAD), where the medial plane is defined by ...

Allopolyploidization events and immense paleogenome reshuffling underlying the diversification of plants and secondary metabolites in Oleaceae

Journal of Systematics and Evolution, Volume 63, Issue 2, Page 208-228, March 2025.
In this study, we revealed the frequent allopolyploidization events and immense paleogenome reshuffling during the diversification of plants in Oleaceae. At the same time, we explored the effects of these ancient evolutionary events on the synthesis of specific secondary metabolites and environmental adaptability of extant plants from Oleaceae ...

First evidence for a massive extinction event affecting bees close to the K-T boundary.

PLoS ONE, 2013
Bees and eudicot plants both arose in the mid-late Cretaceous, and their co-evolutionary relationships have often been assumed as an important element in the rise of flowering plants. Given the near-complete dependence of bees on eudicots we would expect

Tracing the biogeographic history of the world's most isolated insular floras

Journal of Systematics and Evolution, EarlyView.
We inferred the spatio–temporal colonization histories of seven vascular plant lineages (Acaena magellanica, Austroblechnum penna‐marina, Azorella selago, Colobanthus kerguelensis, Notogrammitis crassior, Polystichum marionense, Pringlea antiscorbutica) using phylogenetic, divergence time estimation, and Bayesian Island Biogeographic analyses.

Significant involvement of PEP-CK in carbon assimilation of C4 eudicots [PDF]

Annals of Botany, 2013
C4 eudicot species are classified into biochemical sub-types of C4 photosynthesis based on the principal decarboxylating enzyme. Two sub-types are known, NADP-malic enzyme (ME) and NAD-ME; however, evidence for the occurrence or involvement of the third sub-type (phosphoenolpyruvate carboxykinase; PEP-CK) is emerging.

A reappraisal of the phylogenetic placement of the Aquilegia whole-genome duplication

Genome Biology, 2020
The accurate placement of an ancient whole-genome duplication (WGD) in relation to the lineage divergence is important. Here, we re-investigated the Aquilegia coerulea WGD and found it is more likely lineage-specific rather than shared by all eudicots.

Diversity of Pol IV function is defined by mutations at the maize rmr7 locus. [PDF]

PLoS Genetics, 2009
Mutations affecting the heritable maintenance of epigenetic states in maize identify multiple small RNA biogenesis factors including NRPD1, the largest subunit of the presumed maize Pol IV holoenzyme.
