Diversification of inflorescence development in the PCK clade (Poaceae: Panicoideae: Paniceae)

American Journal of Botany, 2009
In grasses, inflorescence diversification and its correlation with species evolution are intriguing and not well understood. Part of this problem lies in our lack of comprehension about the inflorescence morphological complexity of grasses. We focused our study on the PCK clade (named for phosphoenol pyruvate carboxykinase), a well‐supported ...

Predicted Range Shifts of Non‐Native Grasses in Response to Climate Change Are Influenced by Photosynthetic Pathway: A Case Study in the Hawaiian Islands

Diversity and Distributions, Volume 32, Issue 4, April 2026.
ABSTRACT Aim Grasses comprise three main photosynthetic pathway variants (C3‐BOP, C3‐PACMAD and C4‐PACMAD hereafter referred to as C4). We sought to confirm climate niche differences among these photosynthetic pathway variants and assessed whether predicted non‐native grass range shift patterns with climate change differ among photosynthetic pathway ...

A whole‐genome assembly of St. Augustinegrass and visualizing diversity within the species

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] is a warm‐season turfgrass species in the family Poaceae. This species is a popular choice for lawns in the Southern United States, due to its higher tolerance to shade, heat and humidity.

Grass Communities Differ Floristically Under Different Dominant Trees in Savannas in Thailand and Cambodia

Biotropica, Volume 58, Issue 2, March 2026.
In total, we recorded 160 unique grass species across four savanna ecosystems dominated by different tree genera. These savannas support distinct grassy assemblages, but common grasses are often shared between ecosystems. ABSTRACT Southeast Asian savannas are some of the least studied ecosystems, with understanding of their function and resilience ...

The Role of Awns Evolution in Shaping the Biogeographical History of Pappophorinae (Poaceae: Chloridoideae)

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim We reconstructed the biogeographic history of Pappophorinae and tested whether the evolution of awns is associated with differences in species' geographic ranges. Location Americas. Time Period Miocene. Major Taxa Studies Pappophorinae (Poaceae: Chloridoideae).

Modulation of SAL retrograde signalling promotes yield and water productivity responses in dynamic field environments

New Phytologist, Volume 249, Issue 3, Page 1219-1233, February 2026.
Summary Chloroplast‐to‐nucleus retrograde signalling enables rapid stress responses in plants, but whether these signals accumulate to affect crop performance across entire growing seasons under field conditions remains unknown. We generated wheat mutants with targeted deletions in specific SAL gene copies from two distinct homeologous groups (TaSAL1 ...

Origin of a polyploid accession of Brachiaria humidicola (Poaceae: Panicoideae: Paniceae)

Genetics and Molecular Research, 2009
Brachiaria humidicola, a species adapted to poorly drained and infertile acid soils, is widely used throughout the tropics. Cytological characterization of 54 accessions of B. humidicola for breeding purposes revealed 2n = 36, 42, and 54 chromosomes. One accession (H030), with 2n = 42 chromosomes, showed a different meiotic behavior. In most accessions

Poaceae communities in the savannas of the Amazon Estuary in Brazil

Acta Botânica Brasílica, 2014
We sought to identify the major environmental factors that affect the diversity and distribution of Poaceae in the savannas of the Amazon Estuary. The study was conducted across seven areas of savanna in the Amazon Estuary, within which 160 subplots of 1
