• genetic
  • We are now performing genetic analyses which will help us understand how valuable traits such as disease resistance , malting quality and nitrogen use are inherited. (phys.org)
  • Breeding for plant disease resistance generally has involved finding suitable genetic material amongst existing stocks or in the wild, which is then incorporated into commercial varieties. (wikipedia.org)
  • Therefore, a study was conducted to determine mode of gene action as well as importance of GCA and SCA in the genetic control of CBSD resistance and storage root yield. (springer.com)
  • It is concluded that RPW8 is an essential component of resistance to powdery mildews in A. thaliana , but not the only genetic factor involved in this process. (wiley.com)
  • Infectious disease is a major driver of ecological and evolutionary processes within wild populations, and characterizing the genetic component of host immunity is crucial to understand the genetic basis of variation in infection and to assess the evolutionary impacts of diseases [ 1 ].

  • Jonathan Dallas George Jones FRS (born 14 July 1954) is a senior scientist at the Sainsbury Laboratory and a Professor at the University of East Anglia using molecular and genetic approaches to study disease resistance in plants. (wikipedia.org)
  • Potato
  • For several of the most damaging plant diseases, such as Potato blight (Phytophthora infestans) and white rot (Sclerotic cepivorum) of the Allium family, no acceptable resistant cultivars are yet available. (wikipedia.org)
  • As well as affecting potatoes directly, climate change will also affect the distributions and populations of many potato diseases and pests. (wikipedia.org)
  • As well as affecting potatoes directly, climate change is predicted to affect many potato pests and diseases. (wikipedia.org)
  • They developed this potato for blight resistance by inserting a gene (Rpi-vnt1.1), into the DNA of Désirée potatoes. (wikipedia.org)
  • plants
  • Plants in both natural and cultivated populations carry inherent disease resistance, but this has not always protected them. (wikipedia.org)
  • Disease control is achieved by use of plants that have been bred for good resistance to many diseases, and by plant cultivation approaches such as crop rotation, pathogen-free seed, appropriate planting date and plant density, control of field moisture, and pesticide use. (wikipedia.org)
  • There are a number of lines of defence against pests (that, those animals that cause damage to the plants we grow) and diseases in the orchard, principal among these being the practice of good husbandry, creating healthy soil and ensuring high standards of garden hygiene. (wikipedia.org)
  • Thus, modifying the content of NAD-related metabolites can be used to optimize the defence signalling pathways activated in response to F. graminearum and facilitates the control of disease injury and mycotoxin accumulation in plants. (sigmaaldrich.com)
  • Grafted tomato is also cultivated in France and Italy, and over 20 million tomato plants were grafted in Morocco in 2004 as a way to reduce soilborne disease and increase crop production. (wikipedia.org)
  • immune
  • For example, he contributed some of the early work describing the negative effects of cortisol and stress on immune function and disease resistance in fish, and has helped develop an understanding of the interactions between the endocrine system and the immune system. (wikipedia.org)
  • yield
  • Sometimes however there can be a trade-off, for those varieties which have increased immunity or resistance may be lacking in other qualities such as flavour, yield or quality. (wikipedia.org)
  • Although the vegetable grafting is typically associated with reduction of disease or abiotic stress, yield is often increased without the presence of these identified sources of stress. (wikipedia.org)
  • genotypes
  • Moreover, most studies to date have quantified associations between genotypes and disease status, overlooking the complex relationship between genotype and the properties of the Mhc molecule that interacts with parasites. (royalsocietypublishing.org)
  • cultivars
  • Generally, strategies to prevent flag smut include use of disease resistant cultivars, chemical seed treatments, and crop rotation to reduce amount of inocula present. (wikipedia.org)
  • India and the United States currently have low incidence of this disease due to deployment of resistant cultivars. (wikipedia.org)
  • fungicides
  • In addition to seed treatments, application of systemic fungicides early in the growing season and at low doses is effective at controlling the disease. (wikipedia.org)
  • tolerance
  • Currently, however, grafting is used to offer not only protection from certain diseases, but also tolerance to abiotic stress like flooding, drought, and salinity . (wikipedia.org)
  • The 1937 federal work objectives included goals of improving resistance to disease and improving tolerance of long and short days as well as high and low temperatures. (wikipedia.org)
  • pest
  • But no matter how diverse and healthy the garden eco-system may be, there will always be a degree of disease and pest presence. (wikipedia.org)
  • The most valuable form of resistance is where the pest cannot survive as well on one variety as on another. (wikipedia.org)
  • Goals of modification include introducing pest resistance, tweaking the amounts of certain chemicals produced by the plant, and to prevent browning or bruising of the tubers. (wikipedia.org)
  • RPW8
  • The majority of populations comprised considerable variation both in disease phenotype and RPW8 genotype. (wiley.com)
  • Although resistant individuals shared a major RPW8 genotype, no single allele was uniquely associated with resistance. (wiley.com)
  • late blight
  • In 2014, a team of British scientists published a paper about three-year field trial showing that another genetically modified version of the Désirée cultivar can resist infection after exposure to late blight, one of the most serious diseases of potatoes. (wikipedia.org)
  • whilst
  • A lettuce cultivar that is resistant to mosaic virus may be sensitive to corky root disease, whilst another that resists corky root may be vulnerable to downy mildew (Brim lactic). (wikipedia.org)
  • Whilst dry and hot weather causes the leaf sheaths of the plant to dry and fall off, taking the inoculum with it, thus lessening disease. (wikipedia.org)
  • Hosts
  • These findings suggest that Mhc -linked malaria resistance should also exist in wild avian hosts, a premise supported by the results of several studies in passerine birds [ 16 - 20 ]. (royalsocietypublishing.org)
