Distribution and Pathogenicity Differentiation of Physiological Races of Verticillium dahliae from Cotton Stems in Western China [PDF]

open access: yesPathogens
Verticillium wilt, caused by the pathogenic fungus Verticillium dahliae, has emerged as a severe threat to cotton globally. However, little is known about the genetic diversity of this pathogen in an infected single cotton plant.

Development of blast resistant somaclones of the upland rice cultivar araguaia [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2000
The degree of blast resistance of upland rice (Oryza sativa L.) cultivar Araguaia has decreased over time causing significant yield losses. The major objective of this study was to obtain blast (Pyricularia grisea) resistant somaclones, adapting ...

Physiologic Specialization of Wheat Leaf Rust (Puccinia triticina Eriks.) in theCzech Republic in 2001-2004

open access: yesCzech Journal of Genetics and Plant Breeding, 2006
In 2001-2004 virulence of the wheat leaf rust population in the Czech Republic was studied on Thatcher near-isogenic lines with Lr1, Lr2a, Lr2b, Lr2c, Lr3a, Lr9, Lr10, Lr11, Lr15, Lr17, Lr19, Lr21, Lr23, Lr24, Lr26 and Lr28.

Physiological Rances and Virulence Diversity of Puccinia graminis f. sp. tritici on Wheat in Ethiopia

open access: yesPhytopathologia Mediterranea, 2005
The physiologic races of the rust fungus Puccinia graminis f. sp. tritici in the main wheat-growing regions of Ethiopia were determined on seedlings of the standard wheat stem rust differentials following the international system of nomenclature.

Pleiotropy as the Mechanism for Evolving Novelty: Same Signal, Different Result. [PDF]

open access: yes, 2015
In contrast to the probabilistic way of thinking about pleiotropy as the random expression of a single gene that generates two or more distinct phenotypic traits, it is actually a deterministic consequence of the evolution of complex physiology from the ...

Physiologic specialization of Puccinia triticina in Syria

open access: yesPhytopathologia Mediterranea, 2015
Leaf rust, caused by Puccinia triticina Eriks., is one of the major diseases of wheat in Syria. Surveys of durum wheat fields were carried out in all durum wheat growing regions in Syria during  2010. A total of 120 samples of P. triticina were collected.

The Advantage of Supine and Standing Heart Rate Variability Analysis to Assess Training Status and Performance in a Walking Ultramarathon

open access: yesFrontiers in Physiology, 2020
Cardiac autonomic modulation of heart rate, assessed by heart rate variability (HRV), is commonly used to monitor training status. HRV is usually measured in athletes after awakening in the morning in the supine position.
