Transcriptome analysis of seed development in apomictic Paspalum notatum [PDF]

open access: yes, 2015
The seed developmental process involves various tissues with several ploidy levels and different genetic origins. Therefore, its characterisation at the transcriptome level is certainly a challenge.

Differential responses of bacteria and fungi in the rhizoplane and endosphere of aerial roots of Cissus verticillata

open access: yesEcosphere, Volume 17, Issue 1, January 2026.
Abstract All plant organs have the potential to harbor microbial communities and each organ may form unique niches for specialized microbial communities. There have been very few detailed investigations of microbiomes within a single plant organ along different developmental stages.

Determination of the Developmental Origin of Seeds Containing Endosperm Using Flow Cytometric Analysis

open access: yesBio-Protocol, 2015
Seeds derived from a diploid, sexual plant typically contain a 2n embryo (n+n) and 3n endosperm, a ratio characteristic for most flowering plants. However, this ratio is altered in apomictic species, which reproduce asexually through seeds (Koltunow and ...

Expression analysis of transcription factors from the interaction between cacao and Moniliophthora perniciosa (Tricholomataceae) [PDF]

open access: yes, 2010
Cacao (Theobroma cacao) is one of the most important tropical crops; however, production is threatened by numerous pathogens, including the hemibiotrophic fungus Moniliophthora perniciosa, which causes witches' broom disease. To understand the mechanisms

Evolution of MIR159/319 microRNA genes and their post-transcriptional regulatory link to siRNA pathways [PDF]

open access: yes, 2011
Background MicroRNAs (miRNAs) are prevalent and important endogenous gene regulators in eukaryotes. MiR159 and miR319 are highly conserved miRNAs essential for plant development and fertility.

Deep Genetic Divergence between Disjunct Refugia in the Arctic-Alpine King’s Crown, Rhodiola integrifolia (Crassulaceae) [PDF]

open access: yes, 2014
Despite the strength of climatic variability at high latitudes and upper elevations, we still do not fully understand how plants in North America that are distributed between Arctic and alpine areas responded to the environmental changes of the ...

Reproductive Barriers and Genomic Hotspots of Adaptation During Allopatric Species Divergence

open access: yesMolecular Ecology, Volume 34, Issue 21, November 2025.
ABSTRACT Theory predicts that in allopatric populations, genomic divergence and reproductive barriers may be driven by random genetic drift and thereby evolve slowly in large populations. However, local adaptation and divergence under selection may also play important roles, which remain poorly characterised.

Correction to: Ancient polymorphisms contribute to genome-wide variation by long-term balancing selection and divergent sorting in Boechera stricta

open access: yesGenome Biology, 2019
Following publication of the original article [1], the authors reported that the Availability of data and materials section required updating. The updated text reads as follows:

Evolutionary constraint on low elevation range expansion: Defense‐abiotic stress‐tolerance trade‐off in crosses of the ecological model Boechera stricta

open access: yesEcology and Evolution, 2019
Most transplant experiments across species geographic range boundaries indicate that adaptation to stressful environments outside the range is often constrained. However, the mechanisms of these constraints remain poorly understood.

Circadian rhythms have significant effects on leaf-to-canopy scale gas exchange under field conditions [PDF]

open access: yes, 2016
Background Molecular clocks drive oscillations in leaf photosynthesis, stomatal conductance, and other cell and leaf-level processes over ~24 h under controlled laboratory conditions.
