Water relations traits of C4 grasses depend on phylogenetic lineage, photosynthetic pathway, and habitat water availability [PDF]

open access: yes, 2015
The repeated evolution of C4 photosynthesis in independent lineages has resulted in distinct biogeographical distributions in different phylogenetic lineages and the variants of C4 photosynthesis. However, most previous studies have only considered C3/C4

Phylogenetics of Chloridoideae (Gramineae): a Preliminary Study Based on Nuclear Ribosomal Internal Transcribed Spacer and Chloroplast trnL–F Sequences [PDF]

open access: yes, 2007
The phylogeny of Chloridoideae (Gramineae) was inferred from parsimony analyses of DNA sequences from two genomes—the chloroplast trnL intron, trnL 3\u27 exon, and trnL–F intergenic spacer, and the nuclear ribosomal internal transcribed spacer region ...

Resolving deep relationships of PACMAD grasses: a phylogenomic approach [PDF]

open access: yes, 2015
Background Plastome sequences for 18 species of the PACMAD grasses (subfamilies Panicoideae, Aristidoideae, Chloridoideae, Micrairoideae, Arundinoideae, Danthonioideae) were analyzed phylogenomically.

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

open access: yesClinical & 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 ...

Silicified bulliform cells of Poaceae: morphological characteristics that distinguish subfamilies

open access: yesBotanical Studies, 2020
Background Grass phytoliths are the most common phytoliths in sediments; recognizing grass phytolith types is important when using phytoliths as a tool to reconstruct paleoenvironments.

Genetic Diversity in Swallenia alexandrae (Poaceae, Chloridoideae), a Narrow Endemic From the Eureka Dunes (Inyo County, California) [PDF]

open access: yes, 2013
Swallenia alexandrae, Eureka Valley dune grass (Poaceae, Chloridoideae), is a narrow endemic known only from three localities in the Eureka Valley and adjoining Saline Range in the northern portion of Death Valley National Park (Inyo County, California).

Macro-Climatic Distribution Limits Show Both Niche Expansion and Niche Specialization among C4 Panicoids [PDF]

open access: yes, 2016
Grasses are ancestrally tropical understory species whose current dominance in warm open habitats is linked to the evolution of C4 photosynthesis. C4 grasses maintain high rates of photosynthesis in warm and water stressed environments, and the syndrome ...
