Assortative Mating By Diet In A Phenotypically Unimodal But Ecologically Variable Population Of Stickleback [PDF]

open access: yes, 2008
Speciation with gene flow may be driven by a combination of positive assortative mating and disruptive selection, particularly if selection and assortative mating act on the same trait, eliminating recombination between ecotype and mating type ...

Dactyliform appendage contributes to delayed selfing in the diminutive orchid Stigmatodactylus sikokianus

open access: yesPlants, People, Planet
Societal Impact Statement Understanding plant reproductive strategies is vital for conserving endangered species. This study reveals a novel self‐pollination mechanism in the diminutive orchid Stigmatodactylus sikokianus, facilitated by the movement of a

Histone H3 lysine 36 methylation affects temperature-induced alternative splicing and flowering in plants

open access: yesGenome Biology, 2017
Background Global warming severely affects flowering time and reproductive success of plants. Alternative splicing of pre-messenger RNA (mRNA) is an important mechanism underlying ambient temperature-controlled responses in plants, yet its regulation is ...

Progress and bottlenecks in the early domestication of the perennial oilseed Silphium integrifolium, a sunflower substitute [PDF]

open access: yes, 2018
Silflower (Silphium integrifolium Michx.) is in the early stages of domestication as a perennial version of oilseed sunflower, its close relative. Grain crops with deep perennial root systems will provide farmers with new alternatives for managing soil ...

Genetic Analysis of Axillary Meristem Development in Arabidopsis: Roles of MIR164, CUC1, CUC2, CUC3 and LAS, and identification of novel regulators. [PDF]

open access: yes, 2007
Aerial architecture and reproductive success in higher plants is determined by the formation of secondary axes of growth which are formed by axillary meristems initiated post-embryonically in the axils of leaves.

Life history of Monocystis parasites and genetic diversity of their hosts, the invasive Amynthas earthworms [PDF]

open access: yes, 2016
Monocystis is a parasites in the phylum Apicomplexa that infects nearly 100% of earthworms; however, the parasites have low survivorship, low production of transmissible gametocysts, and seemingly lack schizogony.

Multiple insect pollination contributes to differential phenotypic selection on floral traits in Stellera chamaejasme

open access: yesBMC Plant Biology
Background Flower morphology is believed to be primarily shaped by the most important pollinators when more than one pollinating species visits the flowers.
