Modeling of crop wild relative species identifies areas globally for in situ conservation

open access: yesCommunications Biology, 2019
The impact of climate change is causing challenges for the agricultural production and food systems. More nutritious and climate resilient crop varieties are required, but lack of available and accessible trait diversity is limiting crop improvement ...

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

A near-complete genome assembly of Fragaria iinumae

open access: yesBMC Genomics
Fragaria iinumae, a diploid progenitor species of octoploid strawberries, likely occupies a basal position within the genus Fragaria. In this study, we report a near-complete genome assembly of F.

Distinct late Pleistocene subtropical-tropical divergence revealed by fifteen low-copy nuclear genes in a dominant species in South-East China

open access: yesScientific Reports, 2021
In East Asia, genetic divergence is usually considered to be correlated to different floristic regions, however, subtropical-tropical divergence is largely ignored, compared to widely explored temperate-subtropical divergence.

The prevalence of psittacine circovirus in native and exotic parrots in New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Conservation Biology at Massey University [PDF]

open access: yes, 2005
Psittacine circovirus (PCV) has been identified in more than 60 psittacine species worldwide in both aviary and wild populations. The virus is a causative agent of psittacine circoviral disease (PCD), a highly infectious disease characterised by beak and

Phenolic constituents and antioxidant properties of five wild species of Physalis (Solanaceae)

open access: yesBotanical Studies, 2015
BackgroundFruits of wild species of the genus Physalis are consumed as food and calyces and leaves are used in traditional medicine. The phenolic composition of the species of this genus have been scarcely studied.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

The Loss of the Inverted Repeat in the Putranjivoid Clade of Malpighiales

open access: yesFrontiers in Plant Science, 2020
The typical plastid genome (plastome) of photosynthetic angiosperms comprises a pair of Inverted Repeat regions (IRs), which separate a Large Single Copy region (LSC) from a Small Single Copy region (SSC).

Combining biological approaches to highlight the evolution of Musa complex [PDF]

open access: yes, 2008
The diversity of the banana complex can be deciphered only by jointly characterizing the original wild species and their relatives, the primitive diploid forms and the triploid varieties.
