Biogeographical variation in specific IgE recognition of temperate and subtropical grass pollen allergens in allergic rhinitis patients

Clinical & Translational Immunology, 2020
Objective Globally, grass pollens (GP) are major aeroallergen triggers of allergic rhinitis (AR) and asthma. However, patterns of allergic sensitisation to pollen of temperate (Pooideae: Lolium perenne) and subtropical (Chloridoideae: Cynodon dactylon ...

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 ...

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

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 ...

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 ...

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
