OsPRK1/2/3‐mediated reactive oxygen species signaling is required for pollen tube germination in rice

Journal of Integrative Plant Biology, EarlyView.
The rice pollen‐specific receptor‐like kinases OsPRK1, OsPRK2, and OsPRK3 play a crucial role in reactive oxygen species (ROS)‐mediated pollen hydration and germination. Triple mutants display male sterility due to decreased ROS levels and impaired pollen hydration, and their germination phenotype can be partially restored by exogenous application of ...

Hybridization and gene expression: Beyond differentially expressed genes

Molecular Ecology, EarlyView.
Abstract Gene expression has a key role in reproductive isolation, and studies of hybrid gene expression have identified mechanisms causing hybrid sterility. Here, we review the evidence for altered gene expression following hybridization and outline the mechanisms shown to contribute to altered gene expression in hybrids. Transgressive gene expression,

Sexual Selection on Non‐Ornamental Traits Is Underpinned by Evidence of Genetic Constraints on Sex‐Biased Expression in Dusky Pipefish

Molecular Ecology, EarlyView.
ABSTRACT Species lacking distinct secondary sex characteristics, such as differences in size or morphology, are often thought to experience lower levels of sex‐specific selection in comparison to highly sexually dimorphic organisms. However, monomorphism in classic visible traits could be a result of genetic or physiological constraints that prevent ...

A Chromosome Inversion Creates a Supergene for Sex and Colour in Lake Malawi Cichlids

Molecular Ecology, EarlyView.
ABSTRACT Cichlid fishes have the highest rates of evolutionary turnover of sex chromosomes among vertebrates. Many large structural polymorphisms in the radiation of cichlids in Lake Malawi are associated with sex chromosomes and may also carry adaptive variation.

Developmental Behavioural Plasticity and DNA Methylation Patterns in Response to Predation Stress in Trinidadian Guppies

Molecular Ecology, EarlyView.
ABSTRACT Early‐life experiences can predict the environments experienced later in life, giving individuals an opportunity to develop adaptive behaviour appropriate to a likely future environment. Epigenetic mechanisms such as DNA methylation (DNAm) have been implicated in developmental behavioural plasticity; however, studies investigating this ...

Evolutionary‐conserved RLF, a cytochrome b5‐like heme‐binding protein, regulates organ development in Marchantia polymorpha

New Phytologist, EarlyView.
Summary In Arabidopsis thaliana, REDUCED LATERAL ROOT FORMATION (RLF), a cytochrome b5‐like heme‐binding domain (Cytb5‐HBD) protein, is necessary for proper lateral root (LR) formation. Whereas the other Cytb5‐HBD proteins in A. thaliana regulate different metabolic reactions, RLF is unique as it specifically regulates organ development.
