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

Plant Methods, 2022 Background Phytochemicals or secondary metabolites are low molecular weight organic compounds with little function in plant growth and development. Nevertheless, the metabolite diversity govern not only the phenetics of an organism but may also inform ...

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.

Jasmonate biosynthesis regulates key events in barley vegetative and reproductive development
New Phytologist, EarlyView.Generation and general phenotypes of hvaoc mutants. Summary Cereal grain is a global food staple. Filial tissues in grain, such as the embryo and endosperm, grow embedded in the maternal ovule and surrounding ovary wall. Maternal tissues provide nutrition and protection but are progressively reduced and degraded as filial tissues expand, driving grain ...

The Core Eudicot Boom Registered in Myanmar Amber [PDF]
Scientific Reports, 2018 AbstractA perfect flower in a mid-Cretaceous (early Cenomanian) Myanmar amber is described as Lijinganthus revoluta gen. et sp. nov. The fossil flower is actinomorphic and pentamerous, including calyx, corolla, stamens, and gynoecium. The sepals are tiny, while the petals are large and revolute.

Floral bilateral symmetry: one axis, many details
New Phytologist, EarlyView.Dorsal petal morphological diversity among monkeyflower species. Summary Symmetry is a major component of floral diversity. Most flowers are radially or bilaterally symmetric, with bilateral symmetry (monosymmetry) having evolved repeatedly from radial ancestors. Since the identification of the dorsal identity gene CYCLOIDEA (CYC) in snapdragon, floral

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.

Nature Communications, 2021 Pre-meiotic anthers of monocots accumulate phased, small interfering RNAs (phasiRNAs) that are absent in many well-studied model eudicots. Here, the authors show that such 21-nt phasiRNAs are in fact present in diverse eudicot species including ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Polyploidisation, creating redundant or diverged copies of the genome, is a major driving force in plant evolution, diversification and environmental adaptation, including for the kiwifruit genus (Actinidia Lindl.). We present a high‐contiguity, haplotype‐resolved genome assembly of the hexaploid Actinidia valvata rootstock cultivar ...

Spatial analyses of mono, di and trinucleotide trends in plant genes. [PDF]
PLoS ONE, 2011 Genomic DNA sequences display compositional heterogeneity on many scales. In this paper we analyzed tendencies and anomalies in the occurence of mono, di and trinucleotides in structural regions of plant genes.
