WHEAT STRIPE RUST AND INTEGRATION OF SUSTAINABLE CONTROL STRATEGIES IN CHINA

Frontiers of Agricultural Science and Engineering 2022, Volume 9, Issue 1,   Pages 37-51 doi: 10.15302/J-FASE-2021405

Abstract:

Stripe (yellow) rust caused by Puccinia striiformis f. sp. tritici occurs in almost all wheat-producing regions of the world. Severe countrywide epidemics in China have caused substantial yield losses. Growing resistant cultivars is the best strategy to control this disease but the pathogen can overcome resistance in wheat cultivars. The high variation in the virulence of the pathogen combined with the large areas of susceptible wheat cultivars enables the pathogen population to increase rapidly and disperse over long distances under favorable environmental conditions, resulting in severe pandemics within cropping seasons. Current stripe rust control measures are based on many years of research including the underlying epidemiology regarding year-to-year survival of the pathogen, pathways of pathogen dispersal within seasons and years, the role of P. striiformis sexual hybridization, the use of resistance sources in breeding programs, and year-round surveillance of national wheat crops that are present in different parts of the country throughout the year. All these strategies depend on accurate prediction of epidemics, more precise use of fungicides to meet national requirements and better deployment of resistance genes. New ideas with potential application in sustainable protection of stripe rust include negative regulatory gene editing, resistance gene overexpression and biological control based on microbiomes.

Cytochrome P450 monooxygenase specific activity reduction in wheat

Kangxin HE,Qixing ZHOU

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 2,   Pages 270-275 doi: 10.1007/s11783-015-0813-y

Abstract: Roxithromycin, as widely used medicine and livestock growth promoter, arouses concern because its occurrence and persistence in soil environments. However, effects of roxithromycin in higher plants are still vague. Accordingly, we hypothesized that roxithromycin-contaminated soil may exhibits ecotoxicological effects in wheat ( ). In this study, effects induced by a gradient concentration of roxithromycin stress (0.01, 0.1, 1, 10, and 100 mg·kg ) was investigated in a 7-d soil test in . Results indicated that the specific activity of cytochrome P450 (CYP450) monooxygenase was decreased dramatically with the concentration of roxithromycin in soil. The IC value was 8.78 mg·kg of roxithromycin. On the contrary, the growth related endpoints (i.e., the germination percentage, the biomass and the height), the content related endpoints (i.e., soluble protein content and CYP450 content), and the superoxide dismutase (SOD) activity failed to reveal the roxithromycin-induced effects. Further analysis revealed that the CYP450 monooxygenase specific activity reduction was enzymatic mechanism mediated, other than oxidative stress induced. We conclude that the soil roxithromycin declined the CYP450 monooxygenase activity in by the inhibition of the enzymatic mechanism. Further efforts can include, but are not limited to, investigation of joint effects induced by combined exposure of roxithromycin and the pesticides and evaluation of the similar effects in other higher plants.

Genetic variation of carotenoids in Chinese bread wheat cultivars and the effect of the 1BL.1RS translocation

Wenshuang LI,Shengnan ZHAI,Hui JIN,Weie WEN,Jindong LIU,Xianchun XIA,Zhonghu HE

Frontiers of Agricultural Science and Engineering 2016, Volume 3, Issue 2,   Pages 124-130 doi: 10.15302/J-FASE-2016094

Abstract: Carotenoid content of wheat is an important criterion for prediction of the commercial and nutritional value of products made from bread wheat ( ) cultivars. The objective of this study was to determine the major components of carotenoids in Chinese wheat using ultra performance liquid chromatography (UPLC) including lutein, zeaxanthin, α-carotene and β-carotene. Grain carotenoid content was investigated in 217 cultivars from three major Chinese wheat regions and from seven other countries grown in two environments. Genotype contributed to the majority of variation in carotenoid components. Lutein, zeaxanthin and β-carotene concentrations varied from 18.3 to 100.1, 4.9 to 12.0 and 0.9 to 48.7 μg per 100 g in wheat flour with an average of 40.2, 7.2 and 18.2 μg per 100 g, respectively. Lutein (61.3%) was the main carotenoid component, followed by β-carotene (27.7%) and zeaxanthin (11.0%). No α-carotene was detected. Total carotenoids, lutein, zeaxanthin and β-carotene were all higher in cultivars with the 1BL.1RS translocation compared to those without the translocation. This is the first report on assay of lutein, zeaxanthin and β-carotene concentrations for a large number of wheat cultivars. These data will be useful for genetic improvement of wheat carotenoid content and for understanding of the carotenoid biosynthetic pathway in wheat.

Progress in breeding for resistance to Ug99 and other races of the stem rust fungus in CIMMYT wheat germplasm

Sridhar BHAVANI, David P. HODSON, Julio HUERTA-ESPINO, Mandeep S. RANDHAWA, Ravi P. SINGH

Frontiers of Agricultural Science and Engineering 2019, Volume 6, Issue 3,   Pages 210-224 doi: 10.15302/J-FASE-2019268

Abstract:

Races belonging to the Ug99 (TTKSK) lineage of the wheat stem rust fungus, carrying complex virulence combinations, and their migration to countries in Africa, Middle East and Asia continue to pose a significant threat to global wheat production. The rapid spread of additional races, e.g., TKTTF or the Digalu lineage, in several countries causing localized epidemics reminds us of the vulnerability of wheat germplasm to stem rust disease, a formidable foe referenced as early as biblical times. A global rust monitoring system reflecting increased surveillance efforts has identified 13 races within the Ug99 lineage in 13 countries and unrelated lineages are emerging, spreading and posing serious threats to wheat production. Race TKTTF has caused localized epidemics in Ethiopia and its variants have been recently implicated in stem rust outbreaks in Europe. Concerted research efforts have resulted in the identification of several new resistance (APR) genes and gene combinations for use in breeding. Combining multiple adult plant resistance genes in high-yielding backgrounds and discovery of new quantitative trait loci conferring stem rust resistance has progressed in the recent years, enhancing the durability of resistance. Effective gene stewardship and new generation breeding materials and cultivars that combine multiple race-specific or minor to intermediate effect APR genes, complemented by active surveillance and monitoring, have helped to limit major epidemics and increase grain yield potential in key target environments.
