Molecular ecology and conservation of Mediterranean orchids and their mycorrhizal fungi.
The distribution and abundance of orchid mycorrhizal fungi (OMF) can influence the the establishment and resulting spatial pattern, as well as the population dynamics, of their host plants. Yet, our understanding of these mycorrhizal associations is currently limited by our restricted knowledge of the ecology and spatial distribution of OMF,...Calevo, Jacopo

Species integrity and hybridization in anthropomorphic Orchis species (Orchidaceae).
Hybridization is widespread in Orchis (Orchidaceae), with 38 recorded hybrids between the 21 accepted species. The four anthropomorphic Orchis species that occur in Britain (O. anthropophora, O. militaris, O. purpurea and O. simia) are on the edge of their range and are of high conservation priority. Understanding how these species...Bersweden, Leif

Unravelling the secrets of fern spore germination: what are their thermal thresholds and how will they cope with climate change
Ferns are an important and diverse group of plants. Recruitment from spore to gametophyte represents the first crucial stage in a fern’s development and is responsible for the regeneration of natural populations. However, research into the thermal thresholds for spore germination is deficient and quantitative predictions about how germination may...Steed-Mundin, Olivia

The determinants of geographic variation in within-population genetic diversity: a global meta-analysis
Research has demonstrated that differing levels of genetic diversity within a species can affect how populations respond to disturbance, interact with other species and expand into new ecological niches. The geographic variation in within-population genetic diversity is therefore an important factor in explaining species co-existence, speciation, extinction and ultimately, species...Franz, Madeline

The relationship between antibiotic compounds in wild plant extracts and environmental growing conditions – factors affecting the antimicrobial activity of Allium Ursinum L.
In order to investigate how environmental factors affect plant antibiotic compounds, a literature review of plants with known antibiotic plant activity was carried out, and wild garlic (Allium ursinum L.) chosen as the model organism for the study. 168 individuals were collected from 7 sites across London and its suburban...Burton, George

Novel insight into genome size and succulent trait evolution in Aloe (Asphodelaceae)
Through the evaluation of genomic, anatomical, and physiological characters against the most taxa rich phylogenetic hypothesis of the genus Aloe, this research elucidated succulent trait evolution and relationships governing the ‘succulence syndrome’ within this iconic group. Genome size estimates for 110 species produced 2.7-fold 1C variation and range of 13.49-36.42...Elliott, Kelda

Medicinal and aromatic plants of Pakistan – well documented, effectively conserved and sustainably used
Medicinal and aromatic plants are fundamental to the lives of many people in Pakistan, and numerous species are declining in the wild. In this study, a framework to understand opportunities for conservation and sustainable use of medicinal plants in Pakistan was trialed using eight species as case studies. This framework...Roland, Carlin

The impact of genomic structural variation on meiotic pairing and segregation in Beta vulgaris subsp. maritima
A method of ND FISH was employed to identify structural variation in Beta vulgaris subsp. maritima and to evaluate the impact of this variation on meiotic behaviours, specifically synapsis and segregation of chromosomes. An intercalary region (pEV1) on the chromosome IV arm exhibited asymmetry in signals, allowing individual homologues to...Mian, Sahr

Does climate influence genome size diversity? A study of genome size-environment associations across the Madagascar grass flora
Repetitive DNA accumulation and whole genome duplication are common across angiosperm lineages, resulting in some of the largest ever-recorded genomes, yet the majority of angiosperm species have small genomes. This suggests selection may be acting to reduce genome size (GS), and there is growing evidence of environmental factors influencing GS...Morton, Joseph

Metabolomic and quality discrimination of Stemona tuberosa radix extracts using LC-MSn
Stemona tuberosa has been used as an antitussive medicine and insecticidal agent since the 6th century A.D. With the understanding of alkaloids as the active compounds, previous studies showed that profiles of alkaloids varied significantly, which raised the issue of quality control. Our study firstly demonstrated a considerable intraspecific chemical...Li, Bingyu

DNA barcoding of Pinanga (Arecaceae) of Borneo
The successful application of DNA barcoding as a tool for species discrimination and identification depends on the adequacy of barcode reference libraries of well identified species. Next generation sequencing (NGS) methods have proven to be more promising especially for herbarium specimen containing degraded DNA than conventional barcoding. To make a...Odufuwa, Phebian

Genome size in the UK Fabaceae flora and how this relates to their nitrogen and water tolerance
Genome size (GS) is defined as the total DNA amount in the unreplicated nucleus of an organism, often used synonymously with ‘1C value’. GS varies greatly in flowering plants. Nitrogen (N) and water are considered major limiting factors for plant growth, and their availability could correlate with plants’ GS. Nitrogen...Pollitt, Lauren

Revisiting generic concepts in the Teloschistaceae (lichenforming Ascomycota) using molecular phylogenetics, algorithmic taxa delimitation and molecular networks
In systematics, genera delimitation is constantly changing as taxonomic units above species level are not standardised. The Teloschistaceae, a diverse family of lichenised fungi, represents an extreme example of this where the number of genera has increased tenfold in the last decade. Many of these genera are based solely on...Llewellyn, Theo
