Heterogeneity of iridoid biosynthesis in catmints: Molecular background in a phylogenetic context

Journal of Integrative Plant Biology, EarlyView.
Evolutionary gains and losses of key biosynthetic genes likely resulting from multiple independent evolutionary events explain why certain Nepeta (catnip) species produce both the active, cat‐attracting nepetalactones and sugar‐bound iridoids, while others make only the sugar‐bound forms, and some have lost iridoid production entirely.

Origin and evolution of water oxidation before the last common ancestor of the Cyanobacteria [PDF]

, 2015
Photosystem II, the water oxidizing enzyme, altered the course of evolution by filling the atmosphere with oxygen. Here, we reconstruct the origin and evolution of water oxidation at an unprecedented level of detail by studying the phylogeny of all D1 ...

Biogenic retrograde signaling via GUN1 ensures thermotolerant chloroplast biogenesis during seedling establishment in Arabidopsis thaliana

Journal of Integrative Plant Biology, EarlyView.
Under heat stress, GENOMES UNCOUPLED1 (GUN1) is crucial for the formation of functional chloroplasts in seedlings under heat stress. Without GUN1, chloroplast development fails and seedlings fail to turn green. Therefore, GUN1 helps relay heat‐related cues to maintain chloroplast biogenesis and support thermotolerance during early growth.

Enhancing species discovery and description in algal turfs: A case study in the green alga Pseudoderbesia (Bryopsidales)

Journal of Phycology, EarlyView.
Abstract Algal turfs are assemblages consisting of small marine green, brown, and red algae on the scale of millimeters to a few centimeters. Due to their small size, they have been less intensively studied by macroalgal taxonomists, and they also fall outside the scope of microalgal taxonomists, who tend to focus on smaller, often unicellular, taxa ...

The gene coding for small ribosomal subunit RNA in the basidiomycete Ustilago maydis contains a group I intron [PDF]

, 1992
The nucleotide sequence of the gene coding for small ribosomal subunit RNA in the basidiomycete Ustilago maydis was determined. It revealed the presence of a group I intron with a length of 411 nucleotides.

Species delimitation within the Achnanthidium minutissimum complex (Bacillariophyta), based on morphological, molecular, and ecophysiological approaches

Journal of Phycology, EarlyView.
Abstract The benthic diatom species Achnanthidium minutissimum belongs to a species complex with a challenging taxonomy. Achnanthidium minutissimum has been reported to be a widespread and abundant species occurring in a broad range of freshwater habitats. However, differentiating and delimiting it from other Achnanthidium species is challenging due to

Comparative Plastid Genomics of Non-Photosynthetic Chrysophytes: Genome Reduction and Compaction

Frontiers in Plant Science, 2020
Spumella-like heterotrophic chrysophytes are important eukaryotic microorganisms that feed on bacteria in aquatic and soil environments. They are characterized by their lack of pigmentation, naked cell surface, and extremely small size. Although Spumella-
