Oligogenic | definition of oligogenic by Medical dictionary Oligogenic inheritance for resistance to Zucchini yellow mosaic virus in Cucurbita pepo. Resistance to CMV in melon is recessive and generally oligogenic and quantitative. Monogenic and oligogenic resistance is usually relatively easy to transfer and relatively easy to dissociate from undesirable linkages. This resistance has been termed chlorotic-lesion resistance (l). Vertical resistance: It is determined by one or few genes and is characterized by pathotype specificity. Since the concerned gene is called 'major gene', this resistance is also named major gene resistance. In the case of tolerance, the plant has strategies that helps it to… What does Oligogenic mean? As it is conditioned by one or a few genes, it is called major gene or monogenic of oligogenic resistance. Oligogenic Resistance : Insect resistance is governed by one or few major genes or oligogenes, each gene having a large and identifiable individual effect on resistance. The differences between resistant and susceptible plants are generally . Such resistance is sometimes called partial, general, quantitative is controlled by one or a few genes (thereby the names monogenic or oligogenic resistance). 7 Although the genetic etiology of PCOS remains unknown, a family history of PCOS is relatively common; however, familial links to PCOS are unclear. Although resistance to Fop race 2 was also initially reported as monogenic (Infantino et al., 2006), further analysis of a segregating pea recombinant inbred line population revealed an oligogenic resistance depending on three resistance genes (McPhee et al., 2012). 8. AU - Danesh, D. AU - Aarons, S. AU - McGill, G. E. AU - Young, N. D. Resistant corn stocks with resistance coming from Nigerian introductions supplied Mechanism by which plant develops drought resistance through maintaining favourable water balance is 6. International Crops Research Institute for Semi-Arid and Tropics is situated at 7. ISSN 1940-3372. The cumulative effect of minor genes is called adult resistance or mature resistance or field resistance. Danesh D 1, Aarons S, McGill GE, Young ND. (ŏl″ĭ-gō-jĕn′ĭk, -jēn′) Caused by, affecting, or relating to a small number of genes. Affiliation 1 Department of Plant Pathology . Sharon R. Aarons is a Senior Research Scientist, in the Agriculture Resources Sciences unit at the Ellinbank Dairy Centre, Agriculture Victoria Research of the Victorian State Government, Australia. Vertical resistance (VR) is the resistance that is controlled by one or a few genes hence also called monogenic or oligogenic resistance. However, in some cases, monogenic resistance is very durable. Race-specific is used to describe resistance that interacts differentially with different pathogenic races i.e. Van der Auwera GA, Carneiro MO, Hartl C, et al. Resistance to CMV had previously been reported as oligogenic and recessive (Kar- chi et al. Department of Plant Pathology, 495 Borlaug Hall, University of Minnesota, St. Paul 55108 U.S.A. MPMI 7: 464-471. Definition: Resistance of plants is the property that enables a plant to avoid, tolerate or recover from injury by insect populations that cause greater damage to other plants of the same species, similar environmental conditions. Resistance of a host to all the prevalent races of a pathogen is called horizontal resistance. called Perpendicular resistance, Physiological resistance, seedling resistance, hypersensitivity, race specific resistance or qualitative resistance. Gossypol content in cotton. Horizontal resistance (HR) and VR as meant by Van der Plank (1963), therefore, do not represent different kinds of resistance; they represent, rather, polygenic and oligogenic resistance that is based on the same underlying physiological mechanisms. Resistance and tolerance are plants' best defense mechanisms. Resistance from this accession is oligogenic, with a major effect QTL always detected on chromosome 11 and minor Dissection of the oligogenic resistance to cucumber mosaic virus in the melon accession pi 161375 By A. Essafi, Antonio J. Monforte, Jordi García-Mas, Ana M. Martín-Hernández, Juan A. Díaz-Pendón and Enrique Moriones - Oligogenic resistance: Controlled by few genes - Polygenic resistance: Controlled by many genes - Major gene resistance: Controlled by one or few major genes (vertical resistance) - Minor gene resistance: Controlled by many minor genes. Department of Plant Pathology, 495 Borlaug Hall, University of Minnesota, St. Paul 55108 U.S.A. Sharon Aaarons, Gail E. McGill, and Nevin D. Young. We were able to detect homozygous resistant plants and showed that . It is also known as major gene resistance, oligogenic resistance, race specific resistance and qualitative resistance. PCOS can be described as an oligogenic disorder in which the interaction of a number of genetic and environmental factors determine the heterogeneous, clinical, and biochemical phenotype. In general, monogenic resistance is lesser durable than oligogenic and polygenic resistances. Oligogenic resistance may be conditioned by the dominant or the recessive allele of the concerned gene. This . Each gene consists of a pair of alleles that determine the . The inheritance of disease resistance is governed by these three modes: (1) Oligogenic Resistance: When the resistance is governed by one or few major genes, it is known as oligogenic resistance. TY - JOUR. Oligogenic resistance: Controlled by few genes. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): To understand the process that leads to breakdown of a plant resistance gene, we need to understand the processes that govern pathogen evolution. Instead, resistance appears to have an oligogenic basis. A lack of phenotypic information prevents a . Genetic dissection of oligogenic resistance to bacterial wilt in tomato. Circ Res 2017;120:1084-90. Oligogenic inheritance can be identified by confirming linkage between certain genes. N. D. Young 1, D. Danesh 1, D. Menancio-Hautea 2 & L.
