Persistent postmating, prezygotic reproductive isolation between populations [PDF]
Ecology 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.

Incipient speciation in the rice blast fungus [PDF]
, 2015 Emerging fungal diseases of plants represent a growing issue accompanying global environmental changes, and there is tremendous interest in identifying the factors controlling their appearance and spread.

Convergent and divergent patterns of morphological differentiation provide more evidence for reproductive character displacement in a wood cricket Gryllus fultoni (Orthoptera: Gryllidae) [PDF]
, 2009 Background In ecological character displacement, traits involved in reproductive isolation may not evolve in arbitrary directions when changes in these traits are by-products of adaptation to an ecological niche.

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Loss of sexual isolation in a hybridizing stickleback species pair
Current 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.

A longitudinal study of natural infection of piglets with Streptococcus suis types 1 and 2 [PDF]
, 1991 Streptococcus suis types 1 and 2 were detected in nasal swabs taken from five litters of piglets sampled twice weekly from birth. The two types had been detected in all pigs by the time they were 38 and 25 days old respectively with mean ages of first ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

PLoS 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
Journal 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
Evolution 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.
