  • 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)
  • immune
  • To examine whether L. plantarum C014 had potential for use as an immunostimulant and biocontrol agent in hybrid catfish, the fish diet supplemented with L. plantarum C014 (10 7 CFU/g diet) was prepared and used for the in vivo investigation of its effect on innate immune response and disease resistance of hybrid catfish. (hindawi.com)
  • Based on its origin and beneficial effect on innate immune response and disease resistance, L. plantarum C014 may be a potential candidate for use as a natural and safe immunostimulant and biocontrol agent in hybrid catfish. (hindawi.com)
  • 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)
  • resistant
  • Mwanga hopes that high yielding, pest and disease resistant, and nutritious varieties will be released for farmers in Uganda, and all over Sub-Saharan Africa. (westernfarmpress.com)
  • Since early this century this resistance has been used to develop woolly aphid resistant rootstocks such as MM.106 and M.793. (wikipedia.org)
  • Much later it was shown that the cultivar was also very resistant to collar rot and a useful breeding parent for this resistance. (wikipedia.org)
  • 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)
  • 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)
  • In general it is probably fair to say that resistance will not fully guarantee total crop protection, but choosing resistant varieties should rather be considered as a part of an overall Integrated pest management strategy, especially against virus diseases. (wikipedia.org)
  • Although resistant individuals shared a major RPW8 genotype, no single allele was uniquely associated with resistance. (wiley.com)
  • 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)
  • 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)
  • Potato
  • For instance, a sweet potato could be developed to be able to resist a particular pest or disease, or to thrive in a harsh environment. (westernfarmpress.com)
  • These varieties are steadily being lost due to weevils, sweet potato virus disease and environmental factors. (westernfarmpress.com)
  • 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)
  • 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)
  • RPW8
  • The majority of populations comprised considerable variation both in disease phenotype and RPW8 genotype. (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
  • 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)
  • chemicals
  • 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)
  • wild
  • This gene, which conferred the resistance to blight, was isolated from a wild relative of potatoes, Solanum venturii, which is a native of South America. (wikipedia.org)
  • host
  • Although numerous studies have sought links between Mhc and disease prevalence, many have ignored the ecological and epidemiological aspects of the host-parasite interaction. (royalsocietypublishing.org)
