Bigger genomes provide environment‐dependent growth benefits in grasses

New Phytologist, Volume 244, Issue 5, Page 2049-2061, December 2024.
Summary Increasing genome size (GS) has been associated with slower rates of DNA replication and greater cellular nitrogen (N) and phosphorus demands. Despite most plant species having small genomes, the existence of larger GS species suggests that such costs may be negligible or represent benefits under certain conditions.

Rediscovery of Bouteloua vaneedenii (Gramineae: Chloridoideae): endemic species from the West Indies

Revista Mexicana de Biodiversidad, 2011
Bouteloua vaneedenii is an endemic and extremely rare grass of the West Indies. Very few collections are known, and the most recent collection is from 1922. With the aim of finding the species, a team of Mexican and Cuban agrostologists conducted a field

The genome of Eleocharis vivipara elucidates the genetics of C3–C4 photosynthetic plasticity and karyotype evolution in the Cyperaceae

Journal of Integrative Plant Biology, Volume 66, Issue 11, Page 2505-2527, November 2024.
Eleocharis vivipara provides a prime model for studying photosynthetic plasticity, as it uses C3 photosynthesis underwater and C4 photosynthesis on land. The assembled genome and dynamic gene expression patterns provide new insights into the genetic basis of this photosynthetic transition, which can contribute to crop improvement and breeding ...

Inflorescence diversity in subtribe Eleusininae (Poaceae: Chloridoideae: Cynodonteae)

Flora, 2017
Abstract We studied the inflorescences of 112 members of tribe Chloridoideae subtribe Eleusininae from a morphological and evolutionary perspective to identify the most frequent types and to explore the evolutionary history of selected inflorescence associated characters.

Responses of C4 grasses to aridity reflect species‐specific strategies in a semiarid savanna

Ecosphere, Volume 15, Issue 8, August 2024.
Abstract The C4 Poaceae are a diverse group in terms of both evolutionary lineage and biochemistry. There is a distinct pattern in the distribution of C4 grass groups with aridity; however, the mechanistic basis for this distribution is not well understood.

Preliminary DNA fingerprinting of the turf grass Cynodon dactylon (Poaceae: Chloridoideae)

Bothalia: African Biodiversity & Conservation, 2002
Identification of different cultivars of turf grasses is often very difficult. In a preliminary attempt to identify different cultivars o f Cynodon dactylon (L.) Pers.. random amplified polymorphic DNA (RAPD) analyses of some well-known cultivars used in

Grass pollen surface ornamentation is diverse across the phylogeny: Evidence from northern South America and the global literature

Journal of Systematics and Evolution, Volume 62, Issue 4, Page 687-701, July 2024.
Pollen surface ornamentation shows a high diversity across the Poaceae phylogeny. The different colors and the number of symbols (square or circle) in the grid show the distribution of the 15‐grass pollen morphotypes identified for each specimen in each subfamily. Abstract The grasses are one of the most diverse plant families on Earth.

Pre‐contact and post‐colonial ecological legacies shape Surinamese rainforests

Ecology, Volume 105, Issue 5, May 2024.
Abstract Disturbances in tropical forests can have long‐lasting ecological impacts, but their manifestations (ecological legacies) in modern forests are uncertain. Many Amazonian forests bear the mark of past soil modifications, species enrichments, and fire events, but the trajectories of ecological legacies from the pre‐contact or post‐colonial ...

A 1 Ma sedimentary ancient DNA (sedaDNA) record of catchment vegetation changes and the developmental history of tropical Lake Towuti (Sulawesi, Indonesia)

Geobiology, Volume 22, Issue 3, May/June 2024.
Abstract Studying past ecosystems from ancient environmental DNA preserved in lake sediments (sedaDNA) is a rapidly expanding field. This research has mainly involved Holocene sediments from lakes in cool climates, with little known about the suitability of sedaDNA to reconstruct substantially older ecosystems in the warm tropics.
