Pyrenophora tritici-repentis (Ptr) is the fungal causal agent of the disease tan spot in wheat and causes necrosis and chlorosis in infected leaves. These symptoms are caused by host-selective toxins (HSTs), molecules that serve as the sole determinants of pathogenicity. Ptr has three known HSTs, the proteinaceous Ptr ToxA and...

Pyrenophora tritici-repentis (Ptr) is the fungal causal agent of the
Host-selective toxins (HSTs) secreted by the pathogenic isolate of Pyrenophora tritici-repentis, BFP, are major pathogenicity factors in tan spot disease of wheat. Along with characterized HSTs such as Ptr ToxA (ToxA), BFP secretes at least two more uncharacterized toxic components. In an attempt to identify these additional components, 12 candidate...
Pyrenophora tritici-repentis (Ptr) is the causal agent of the disease tan spot of wheat,
which can be responsible for the destruction of up to 50% of a wheat crop harvest.
Tan spot disease results in chlorotic and/or necrotic lesions triggered by the
pathogen’s production of one or several host-selective toxins...

Pyrenophora tritici-repentis (Ptr) is the causal agent of the disease
Pyrenophora tritici-repentis (Ptr) is the necrotrophic fungus responsible for tan spot of wheat (Triticum aestivum). Ptr causes disease on susceptible wheat cultivars through the production and secretion of host-selective toxins (HSTs). HSTs are compounds that are only known to be produced by fungi and considered to be primary determinants of...
Pyrenophora tritici-repentis, causal agent of tan spot of wheat, produces multiple
host-selective toxins (HSTs), including Ptr ToxA, encoded for by ToxA, Ptr ToxB,
encoded for by ToxB, and Ptr ToxC. Variable distribution of these three HSTs among
different isolates of P. tritici-repentis, both singularly and in all possible combinations,
defines...
Graphium sp., a eukaryotic alkanotroph, is able to oxidize small-molecular weight gaseous n-alkanes, diethyl ether and the branched ether, methyl tert butyl ether
(MTBE). However, information regarding the biochemistry of fungal-mediated alkane and ether metabolism is limited, and questions regarding the identity of alkane oxidation catalysts and the genetic underpinnings...
The purpose of the study was to explore the possible acceptance of
metric conversion for clothing sizes and sizing standardization by a
selected sample of female ready-to-wear clothing consumers.
A questionnaire was designed to elicit consumer's positive or negative
attitudes toward metric conversion for clothing sizes and sizing
standardization. The...
The utero-ovarian vasculature of domestic animals has been a
popular research subject, especially concerning the roles of the uteroovarian
artery and vein in the unilateral luteolytic phenomenon
demonstrated in these animals. No reports in the literature, however,
have been found regarding the smooth muscle physiology of these vessels.
The present...
Some elementary teachers want to be more child-centered in their
teaching. They are trying to consider the needs of the students
before the coverage of curriculum. Much of the inspiration for this
educational approach has come from the British primary schools.
The purpose of this study was to see if...
