Physiological Races of Phytophthora infestans in Korea [PDF]

open access: yesThe Plant Pathology Journal, 2007
A total of the 261 Phytophthora infestans isolates collected from 2003 to 2005 in Korea were investigated for their physiological race composition. Among the isolates, we detected 18 physiological races and the dominant races were R0.1.3.5.6.10.11 and R0.1.3.5.6.7.10.11 with frequencies of 18.4% and 11.4%, respectively. All of the P.

Wheat leaf rust races/pathotypes in the Czech Republic in 1997-1998

open access: yesPlant Protection Science, 1999
In 1997-1998 virulence of the wheat leaf rust population was studied on Thatcher near isogenic lines with Lr1, Lr2a, Lr2b, Lr2c, Lr3. Lr9, Lrll, Lrl5, Lrl7, Lrl9, Lr21, Lr23, Lr24, Lr26 and Lr28. On these NILs 11 pathotypes were determined in 1997, and 8

ADULT PLANT RESISTANCE IN WHEAT TO PHYSIOLOGIC RACES OF PUCCINIA TRITICINA ERIKSS.

open access: yes, 1943
Nine wheat varieties were studied in two stages of growth, the seedling stage and the heading stage, for their reaction to a number of physiologic races of leaf rust of wheat, Puccinia triticina Erikss.

ENVIRONMENTAL REACTION OF PHYSIOLOGIC RACES OF PUCCINIA TRITICINA AND THEIR DISTRIBUTION IN CANADA

open access: yes, 1941
Studies were made of the effect of temperature and light on the reactions to leaf rust (Puccinia triticina Erikss.) of the differential varieties of wheat used for the identification of physiologic races of this rust.

Wheat leaf rust races/pathotypes in the Czech Republic in 1999-2000

open access: yesPlant Protection Science, 2001
In 1999-2000 virulence of the wheat leaf rust population was studied on Thatcher near isogenic lines (NILs) with Lr1, Lr2a, Lr2b, Lr2c, Lr3, Lr9, Lr10 (only in 2000), Lr11, Lr15, Lr17, Lr19, Lr21, Lr23, Lr24, Lr26 and Lr28.

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.
