The past, present, and future of ecogeographic isolation between closely related Aquilegia plants

open access: yesEcology and Evolution, 2023
Quantifying the strength of the ecogeographic barrier is an important aspect of plant speciation research, and serves as a practical step to understanding the evolutionary trajectory of plants under climate change.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Persistent postmating, prezygotic reproductive isolation between populations [PDF]

open access: yesEcology and Evolution, 2018
ABSTRACTStudying reproductive barriers between populations of the same species is critical to understand how speciation may proceed. Growing evidence suggests postmating, prezygotic (PMPZ) reproductive barriers play an important role in the evolution of early taxonomic divergence.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Loss of sexual isolation in a hybridizing stickleback species pair

open access: yesCurrent Zoology, 2013
One approach to understand the importance of reproductive barriers to the speciation process is to study the breakdown of barriers between formerly distinct species.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

A tale of two morphs: modeling pollen transfer, magic traits, and reproductive isolation in parapatry.

open access: yesPLoS ONE, 2014
The evolution of the flower is commonly thought to have spurred angiosperm diversification. Similarly, particular floral traits might have promoted diversification within specific angiosperm clades.

Prospects of utilization of inter-subspecific heterosis between indica and japonica rice

open access: yesJournal of Integrative Agriculture, 2020
The Asian cultivated rice (Oryza sativa L.) grown worldwide is divided into two subspecies, indica and japonica. It is well known that the heterosis of inter-subspecies is usually stronger than that of intra-subspecies.

Divergence and introgression among the virilis group of Drosophila

open access: yesEvolution Letters, 2022
Speciation with gene flow is now widely regarded as common. However, the frequency of introgression between recently diverged species and the evolutionary consequences of gene flow are still poorly understood.

Morphometry of fruits and pyrenes in two morphotypes and populations of Butia purpurascens Glassman (Arecaceae)

open access: yesCiência Rural, 2022
: Morphometry of fruits and seeds is a useful and important information for phenotyping and genetic characterization of crop plant species and, for conservation of endangered species, as is the case of Butia purpurascens Glassman.
