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... -

Molecular evidence of species- and subspecies-level distinctions in the rare Orchis patens s.l. and implications for conservation
Characterizing genetic diversity and structure of populations is essential for the effective conservation of threatened species. Orchis patens sensu lato is a narrowly distributed tetraploid species with a disjunct distribution (i.e., Northern Italy, North Africa and the Canary Islands), which is facing a severe decline.

The Cryobiotechnology of Oaks: An Integration of Approaches for the Long-Term Ex Situ Conservation of Quercus Species
Conventional dry seed storage is unlikely for about one third of all tree species (and nearly half of evergreen rain forest trees) as they probably produce desiccation sensitive (recalcitrant) seeds. Consequently, international ex situ conservation targets for threatened trees will be difficult to achieve without innovation, especially in cryobiotechnology. We...Ballesteros, Daniel ; Pritchard, Hugh W.

A haplotype-led approach to increase the precision of wheat breeding
Crop productivity must increase at unprecedented rates to meet the needs of the growing worldwide population. Exploiting natural variation for the genetic improvement of crops plays a central role in increasing productivity. Although current genomic technologies can be used for high-throughput identification of genetic variation, methods for efficiently exploiting this...Brinton, Jemima ; 10 Wheat Genome Project ; Ramirez-Gonzalez, Ricardo H. ; Simmonds, James ; Wingen, Luzie …

Patterned Villagescapes and Road Networks in Ancient Southwestern Amazonia
Our recent data, collected using remotely sensed imagery and unmanned aerial vehicle surveys, reveal the extremely well-defined patterning of archaeological plaza villages in the Brazilian Acre state in terms of size, layout, chronology, and material culture. The villages comprise various earthen mounds arranged around central plazas and roads that radiate... -

A new artificial hybrid – Salix × kirchneri I.V.Belyaeva & O.V.Epanch. (Salicaceae).
A new artificial hybrid, Salix × kirchneri I.V.Belyaeva & O.E.Epanch., is described. The identities of the parent taxa Salix glauca L. f. cordifolia (Pursh) I.V.Belyaeva and Salix nakamurana Koidz. f. yezoalpina (Koidz.) H.Ohashi are discussed and a new combination, Salix glauca f. cordifolia (Pursh) I.V.Belyaeva, is made. The name, Salix...Belyaeva, Irina V. ; Epanchintseva, Olga V. ; Semkina, Lidia A.

The inclusion of Akeassia in Grangea (Asteraceae) and description of a new species from Gabon: Grangea ogoouensis
The discovery of a new Gabonese species of Asteraceae leads us to reevaluate the distinction between the genera Grangea Adans. and Akeassia J.-P. Lebrun & Stork. The differences between the two genera proving unreliable, Akeassia is included in Grangea, resulting in the new combination Grangea grangeoides (J.-P.

Neotypification of Pandanus odorifer, the correct name for P. odoratissimus (Pandanaceae)
Pandanus odorifer (Pandanaceae) is an economically important species distributed on coasts from India and Sri Lanka to South China through tropical Asian countries. Pandanus odoratissimus has been widely used as the accepted name for the species, but P. odoratissimus is in reality a superfluous and illegitimate name. No original material... -

A new combination in the genus Tripidium (Poaceae: Andropogoneae)
The genus Tripidium Scholz in Valdés & Scholz (2006: 664) (Poaceae: Andropogoneae) currently includes six species, distributed in Asia, southern Europe, and northern Africa, with the greatest diversity in India (Welker et al. 2019). The species of Tripidium have traditionally been treated as part of the “Saccharum complex”, formed by...WELKER, CASSIANO A. DORNELES ; VORONTSOVA, MARIA S. ; KELLOGG, ELIZABETH A.

Isolation, Library Preparation, and Bioinformatic Analysis of Historical and Ancient Plant DNA
The ability to sequence DNA retrieved from ancient and historical material plays a crucial role in reinforcing evolutionary and anthropological inference. While the focus of the field is largely on analyzing DNA from ancient hominids and other animals, we have also learned from plant ancient DNA (aDNA), in particular, about... -

Further new species and records from the coastal dry forests and woodlands of the Rovuma Centre of Endemism
Background and aims – The coastal dry forests and woodlands of Cabo Delgado Province (Mozambique), part of the proposed Rovuma Centre of Endemism that is shared with coastal southern Tanzania, are known to support high numbers of endemic and highly range-restricted species. Here we investigate the taxonomic status of three...Darbyshire, Iain ; Goyder, David J. ; Wood, John R.I. ; Banze, Aurélio ; Burrows, John E.

Functional seed traits and germination patterns predict species coexistence in Northeast Mediterranean foredune communities
Background and Aims The structure of plant communities, which is based on species abundance ratios, is closely linked to ecosystem functionality. Seed germination niche plays a major role in shaping plant communities, although it has often been neglected when explaining species coexistence. The aim of this work is to... -

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... -

Acanthostachys calcicola (Bromeliaceae, Bromelioideae), a new species from a limestone outcrop in Tocantins State, Brazil
A new species of bromeliad, Acanthostachys calcicola, a third taxon for the genus, is here described. A. calcicola was discovered during field work in the limestone outcrops of south-eastern Tocantins, central Brazil. It is most similar to A. strobilacea, but differs from it in petal colour and length, and exserted... -

Combining the small South American genus Androtrichum into Cyperus (Cyperaceae)
Background and aims – Molecular phylogenetic studies have provided a clearer understanding of the complex relationships within the family Cyperaceae. These studies have consistently shown that 12 allied genera are nested in the genus Cyperus. However, early Sanger sequencing-based phylogenies that included the two species of the small South American...Pereira-Silva, Luciana ; Trevisan, Rafael ; Rodrigues, Ana Claudia ; Larridon, Isabel

What drives diversification in a pantropical plant lineage with extraordinary capacity for long‐distance dispersal and colonization?
Aim Colonization of new areas may entail shifts in diversification rates linked to biogeographical movement (dispersification), which may involve niche evolution if species were not exapted to new environments. Scleria (Cyperaceae) includes c. 250 species and has a pantropical distribution suggesting an extraordinary capacity for long‐distance dispersal and colonization. We...Larridon, Isabel ; Galán Díaz, Javier ; Bauters, Kenneth ; Escudero, Marcial

Evolutionary dynamics of transposable elements and satellite DNAs in polyploid Spartina species
Repeated sequences and polyploidy play a central role in plant genome dynamics. Here, we analyze the evolutionary dynamics of repeats in tetraploid and hexaploid Spartina species that diverged during the last 10 million years within the Chloridoideae, one of the poorest investigated grass lineages. From high-throughput genome sequencing, we annotated...Giraud, Delphine ; Lima, Oscar ; Huteau, Virginie ; Coriton, Olivier ; Boutte, Julien …

Setting scientific names at all taxonomic ranks in italics facilitates their quick recognition in scientific papers
It is common practice in scientific journals to print genus and species names in italics. This is not only historical as species names were traditionally derived from Greek or Latin. Importantly, it also facilitates the rapid recognition of genus and species names when skimming through manuscripts. However, names above the...Thines, Marco ; Aoki, Takayuki ; Crous, Pedro W. ; Hyde, Kevin D. ; Lücking, Robert …
