The seed germination spectrum of alpine plants: a global meta‐analysis
Assumptions about the germination ecology of alpine plants are presently based on individual species and local studies. A current challenge is to synthesize, at the global level, the alpine seed ecological spectrum. We performed a meta‐analysis of primary data from laboratory experiments conducted across four continents (excluding the tropics) and... -

Regulation of seed germination by diurnally alternating temperatures in disturbance-adapted banana crop wild relatives (Musa acuminata).
Seed conservation of banana crop wild relatives (Musa L. spp.) is limited because of lack of knowledge about their germination ecology. Musa acuminata Colla, the most important banana crop wild relative, is distributed in tropical and subtropical Asian and Pacific rainforests and colonizes disturbed sites. The role of temperature in... -

Challenges for Ex Situ Conservation of Wild Bananas: Seeds Collected in Papua New Guinea Have Variable Levels of Desiccation Tolerance.
Ex situ seed conservation of banana crop wild relatives (Musa spp. L.), is constrained by critical knowledge gaps in their storage and germination behaviour. Additionally, challenges in collecting seeds from wild populations impact the quality of seed collections. It is, therefore, crucial to evaluate the viability of seeds from such... -

Drying banana seeds for ex situ conservation.
The ability of seeds to withstand drying is fundamental to ex situ seed conservation but drying responses are not well known for most wild species including crop wild relatives. We look at drying responses of seeds of Musa acuminata and Musa balbisiana, the two primary wild relatives of bananas and...Kallow, Simon ; Garcia Zuluaga, Manuela ; Fanega Sleziak, Natalia ; Nugraha, Bayu ; Mertens, Arne …

Genetic diversity and structure of Musa balbisiana populations in Vietnam and its implications for the conservation of banana crop wild relatives.
Crop wild relatives (CWR) are an indispensable source of alleles to improve desired traits in related crops. While knowledge on the genetic diversity of CWR can facilitate breeding and conservation strategies, it has poorly been assessed. Cultivated bananas are a major part of the diet and income of hundreds of...Mertens, Arne ; Bawin, Yves ; Vanden Abeele, Samuel ; Kallow, Simon ; Vu Dang, Toan …

Presentation
Evolution and functional ecology of the embryo to seed size ratio.
Continuous variation exists in the ratio of embryo to nutritive tissues of Angiosperms. Embryo to seed size ratio ranges from seeds dispersed with an embryo consisting of a clump of cells embedded in copious endosperm, e.g. several Ranunculaceae, to seeds containing only an embryo and no nutritive tissue, e.g. many...Vandelook, Filip ; Dickie, John B. ; Carta, Angelino

Wild bananas detect forest gaps.
Banana crop wild relatives (CWR) grow in tropical to sub-tropical Asia and Pacific forest. They take advantage of forest disturbances to form patches in the forest or on the edges of cleared land. We investigate the mechanism by which seeds from banana CWRs are able to detect gaps and germinate...Kallow, Simon ; Davies, Rachael ; Janssens, Steven B. ; Vandelook, Filip ; Panis, Bart …

A large-scale species level dated angiosperm phylogeny for evolutionary and ecological analyses.
Phylogenies are a central and indispensable tool for evolutionary and ecological research. Even though most angiosperm families are well investigated from a phylogenetic point of view, there are far less possibilities to carry out large-scale meta-analyses at order level or higher. Here, we reconstructed a large-scale dated phylogeny including nearly...Janssens, Steven ; Couvreur, Thomas L.P. ; Mertens, Arne ; Dauby, Gilles ; Dagallier, Leo-Paul …

Correlated evolution of seed mass and genome size varies among life forms in flowering plants.
Seeds show important variation as plant regenerative units among species, but their evolutionary co-variations with other plant characteristics are still poorly understood. Whilst a positive association of seed mass with genome size (GS) and life forms has already been documented, a broad-scale quantification of their evolutionary correlation and adaptive selection... -

Phylogeography and conservation gaps of Musa balbisiana Colla genetic diversity revealed by microsatellite markers.
Collection and storage of crop wild relative (CWR) germplasm is crucial for preserving species genetic diversity and crop improvement. Nevertheless, much of the genetic variation of CWRs is absent in ex situ collections and detailed passport data are often lacking. Here, we focussed on one of the two main progenitor...Mertens, Arne ; Bawin, Yves ; Vanden Abeele, Samuel ; Kallow, Simon ; Swennen, Rony …

Technical report
Global strategy for the conservation and use of Vigna.
This publication aims to provide a framework for the efficient and effective <em>ex situ</em> conservation of globally important collections of <em>Vigna</em> crops and their wild relatives. The development of this Global Crop Conservation Strategy was funded by the German Federal Ministry of Food and Agriculture (BMEL) as part of the... -
