Disease relevance of Poaceae


High impact information on Poaceae

  • In the Gramineae, the cyclic hydroxamic acids 2,4-dihydroxy-1, 4-benzoxazin-3-one (DIBOA) and 2,4-dihydroxy-7-methoxy-1, 4-benzoxazin-3-one (DIMBOA) form part of the defense against insects and microbial pathogens [2].
  • To cope with low iron supply, plants with the exception of the Gramineae increase the solubility and uptake of iron by inducing physiological and developmental alterations including iron reduction, soil acidification, Fe(II) transport and root-hair proliferation (strategy I) [3].
  • Molecular phylogenies of the Poaceae based upon Adh1 data are presented [4].
  • Ole e 10 shares IgE B cell epitopes with proteins from Oleaceae, Gramineae, Betulaceae, Chenopodiaceae, Cupressaceae, Ambrosia, and Parietaria pollens, latex, and vegetable foods, such as tomato, kiwi, potato, and peach [5].
  • Benzoxazinoid acetal glucosides are a unique class of natural products abundant in Gramineae, including the major agricultural crops maize, wheat, and rye [6].

Biological context of Poaceae

  • We investigated nucleotide polymorphism in the Adh1 locus of pearl millet (Pennisetum glaucum) (Poaceae) by determining the DNA sequence of 20 alleles from 10 individuals [7].
  • Therefore, these results suggest that TEL is not only associated with leaf initiation but more generally with cell differentiation in Poaceae [8].
  • Molecular evolution and phylogenetic utility of the chloroplast rpl16 intron in Chusquea and the Bambusoideae (Poaceae) [9].
  • Minute inversions (4 bp in length), associated with probable hairpin secondary structures, were inferred from comparative analysis of rpl16 intron sequences from the chloroplast genomes of Chusquea species and related bamboos (Poaceae) [10].
  • Chromosome number and flavonoid synthesis in Briza L. (Gramineae) [11].

Anatomical context of Poaceae

  • Two other cell-wall preparations, representing lignified walls of dicotyledons and unlignified walls of vegetative parts of grasses and cereals (monocotyledons belonging to the family Poaceae), adsorbed DNP much more effectively [12].

Associations of Poaceae with chemical compounds

  • In dicotyledonous plants there are three SPS gene families: A, B, and C. Here we report the finding of five families of SPS genes in wheat (Triticum aestivum) and other monocotyledonous plants from the family Poaceae (grasses) [13].
  • OBJECTIVE: We investigated whether water-induced release of respirable allergen-bearing particles could be a mechanism common to several members of the sweet grass family Poaceae (Gramineae) [14].
  • Exposure of several species of the family Poaceae to cadmium results in the formation of metal-induced peptides of the general structure (gamma-Glu-Cys)n-Ser (n=2-4) [15].
  • Nucleotide variability at the acetyl coenzyme A carboxylase gene and the signature of herbicide selection in the grass weed Alopecurus myosuroides (Huds.) [16].
  • Despite ongoing research on carotenoid biosynthesis in model organisms, there is a paucity of information on pathway regulation operating in the grasses (Poaceae), which include plants of world-wide agronomic importance [17].

Gene context of Poaceae

  • PHYA and PHYB in eudicots are evolving at least 1.45 times as fast as their counterparts in the Poaceae [18].
  • A phylogenetic analysis with partial plant cDNA sequences suggested that copg gene was also duplicated in the grass family (Poaceae) [19].
  • This study proves the rps4 gene to be a useful phylogenetic tool within the Poaceae family and the Monocotyledonae order [20].
  • The noncoding DNA region of the chloroplast genome, flanked by the genes rbcL and psaI (ORF36), has been sequenced for seven species of the grass family (Poaceae) [21].
  • Putative ADR1 homologs were identified in 11 species including rice and in 3 further Poaceae species [22].

Analytical, diagnostic and therapeutic context of Poaceae

  • Using degenerate primers, one unique tel (terminal ear1-like) gene from seven Poaceae members, covering almost all the phylogenetic tree of the family, was identified by PCR [8].
  • In terms of allergenicity, Saccharum officinarum (sugar cane) of Poaceae, showed highest reactivity (70.58%) in skin test carried out in 189 adult agricultural field workers with respiratory disorders living inside the study area [23].
