| Wheat leaf rust occurs wherever wheat is grown, and it is the commonest, most widely distributed of all cereal rusts. | |
| With frequent and severe outbreaks, disease resistance is a key tool for controlling stripe rust on wheat. | |
| All but two genotype-race combinations showed a susceptible infection type, which indicates that partial resistance of wheat to wheat leaf rust caused the major part of this interaction. | |
| (15) Some of the most susceptible varieties of wheat and barley even when exposed in the open for over ten months do not become affected by yellow rust if the viability of the uredospores (the only source of infection) is impaired. | |
12 Citations | The Genes found effective against yellow rust under natural conditions may be deployed singly or in combinations with durable resistance genes to develop high yielding resistant wheat cultivars in wheat-growing areas in where yellow rust races have the same virulence profile to the prevalent race/s of Ardabil. |
86 Citations | The semidwarf wheats of the Green Revolution were also less vulnerable to rust diseases than the tall varieties previously released by plant breeding programs as well as traditional varieties. |
| This approach may help understanding the wheat - P. triticina interaction and provide information to build an effective management program for leaf rust disease. | |
| (7) The dwarf rust of barley and the yellow rust of wheat cannot infect other cereals. | |
75 Citations | Based on their efficiency and eco-safety, we can recommend the use of this combination in controlling stem rust disease of wheat. |
| Results indicated that the tested plant extracts could induce wheat resistance to leaf rust. | |
14 Citations | This suggests adult‐plant resistance to stem rust may be present in German wheat cultivars. |
28 Citations | These results indicate that the first NO burst in the immune system plays an important role in the resistant reaction of wheat to strip rust. |

Can correlation and path analysis be used to identify the main genetic factors influencing rust disease in bread wheat?5 answersCorrelation and path analysis can indeed be utilized to identify the primary genetic factors influencing rust diseases in bread wheat. Studies have shown that conducting genome-wide association studies (GWAS) can help pinpoint specific genomic loci associated with resistance to leaf rust caused by Puccinia triticina. Additionally, genetic analyses have been instrumental in determining the population structure and diversity of Puccinia striiformis f. sp. tritici, the causal agent of wheat stripe rust, aiding in understanding the sources and dispersal routes of the pathogen. By identifying marker-trait associations (MTAs) and candidate genes related to leaf rust resistance, researchers can enhance breeding programs by incorporating novel genetic factors into wheat varieties to combat rust diseases effectively. This integrated approach provides valuable insights into the genetic basis of rust diseases in bread wheat.
What is the most important fungal diseases that affect australian wheat production?4 answersThe most important fungal diseases affecting Australian wheat production include tan spot caused by Pyrenophora tritici-repentis (Ptr) and Fusarium crown rot (FCR) caused by Fusarium pseudograminearum (Fp). Tan spot is a significant disease with necrotrophic fungal effectors ToxA, ToxB, and ToxC influencing Ptr race classification, showcasing a complex regulatory process in Australian isolates. On the other hand, FCR poses a threat due to its impact on yield and grain quality, with variations in mating type composition and genetic diversity observed among Fp isolates from different Australian regions. These diseases highlight the importance of continuous monitoring and implementing effective disease management strategies to safeguard Australian wheat crops and ensure sustainable production.
What are the most prominent diseases in barley?5 answersThe most prominent diseases affecting barley include rusts, net blotches, spot blotches, powdery mildew, barley yellow dwarf, molya disease, barley stripe disease, barley net spot disease, barley leaf spot, and barley leaf scald. These diseases lead to significant yield losses and quality deterioration in barley crops, impacting agricultural output globally. Integrated disease management strategies, such as developing disease-resistant varieties and monitoring disease agents in specific regions, are crucial for sustainable agriculture and mitigating the impact of these diseases on barley production. Additionally, the use of nanomaterials has shown promise in reducing disease incidence and improving barley seed germination, physiology, and grain quality. Continuous research and implementation of effective management practices are essential to combat these prevalent barley diseases and ensure optimal crop productivity.
Can trees help reducing the damages by pests and diseases on wheat?5 answersTrees can help reduce the damages caused by pests and diseases on wheat. The presence of trees in wheat planting fields can create a more favorable environment for wheat growth and reduce the incidence of diseases and pests. Trees can provide shade and shelter, which can help regulate temperature and humidity, creating conditions less favorable for pests and diseases to thrive. Additionally, trees can act as a physical barrier, preventing the spread of diseases and pests from neighboring fields. Furthermore, the use of plant-source pesticides derived from trees can help control pests and diseases in wheat fields. Overall, incorporating trees into wheat planting systems can contribute to the prevention and control of diseases and pests, leading to increased wheat yield and improved food safety.
What are the most extensively used yellow rust resistance genes in wheat?2 answersThe most extensively used yellow rust resistance genes in wheat include Lr34, Lr46/Yr29, and Lrk10. These genes have been identified and utilized in breeding programs to confer resistance to yellow rust caused by Puccinia striiformis. Lr34 is a race non-specific resistance gene that provides durable resistance when used in combination with other genes. Lr46/Yr29 is a pleiotropic slow-rusting adult plant resistance gene that interacts with additional unidentified genes. Lrk10 is closely linked to Lr10 and has been cloned, with its function recognized. These genes play a crucial role in achieving durable resistance to yellow rust in wheat and are of interest for further characterization and utilization in breeding programs.
What are the most common diseases in wheat in India?4 answersThe most common diseases in wheat in India are spot blotch and rust diseases. Spot blotch, caused by Bipolaris sorokiniana, is the most dominant disease in the eastern Gangetic plains of the Indian subcontinent, leading to yield loss of more than 15% even with the use of moderately resistant varieties. Rust diseases, which are not specified further, are also prevalent in wheat. In terms of foliar blight pathogens, Coehliobolous sativus, Alternaria triticina, Pyrenophora tritici-repentis, and C. spieifer are the major pathogens found in wheat samples from various states in India. Additionally, foliar blight caused by Bipolaris sorokiniana has become a major wheat disease in India, affecting both traditional tall wheat varieties and dwarf high yielding cultivars. Alternaria blight, caused by Alternaria triticina, has also gained prominence due to the susceptibility of Mexican wheats to the fungus.
