Mechanical Strength: An Unrecognised Target in the Genetic Improvement of Crops

Plant Biotechnology Journal, Volume 24, Issue 6, Page 4190-4203, June 2026.
ABSTRACT Leaf angle (LA) is a crucial agronomic trait influencing planting density and crop yield. Previous research highlighted the importance of cellular variations in the ligular region for determining LA, but the underlying regulatory mechanisms remain unclear.

A pleiotropic “stretch” phenotype is associated with metaxylem vessel element length, axial hydraulic conductance, root elongation, water utilization, and drought adaptation in maize

Crop Science, Volume 66, Issue 3, May/June 2026.
Abstract We tested the hypothesis that metaxylem phenotypes influence drought adaptation in maize (Zea mays L.) through in silico modeling and empirical studies under water deficit in controlled environments and in the field. Substantial genotypic variation for metaxylem vessel element length (MVEL) was observed. Longer MVEL was correlated with reduced

Drought responses of selected C₄ photosynthetic NADP-Me and NAD-Me Panicoideae and Aristidoideae grasses [PDF]

, 2015
Grass species within South Africa show a photosynthetic subtype and phylogenetic response to rainfall gradients, with Panicoideae species (NADP-Me and NAD-Me) inhabiting mesic environments, while Aristidoideae species (NADP-Me) inhabit more arid ...

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.

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

[Leaf epidermis ultrastructure of Zeugites (Poaceae: Panicoideae)].

Revista de biologia tropical, 2011
The genus Zeugites comprises eleven species of neotropical grasses and it is principally distributed in Mexico, with some species extending to the Caribbean region, Central and South America. In this work, leaf epidermis ultrastructure of 11 species is described by the use of scanning electron microscopy.

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 ...

Kranz distinctive cells in the culm of ArundineUa (Arundinelleae; Panicoideae; Poaceae)

Bothalia, 1990
The transectional anatomy of photosynthetic flowering culms of Arundinella berteroniana (Schult.) Hitchc. Chase and A. hispida (Willd.) Kuntze from South America and A.  nepalensis Trin. from Africa is described and illustrated. The vascular bundles are arranged in three distinct rings, the outermost being external to a continuous sclerenchymatous ...
