Genomic approaches to plant disease resistance.
نویسنده
چکیده
Genomic approaches are beginning to revolutionize our understanding of plant disease resistance. Large-scale sequencing will reveal the detailed organization of resistance-gene clusters and the genetic mechanisms involved in generating new resistance specificities. Global functional analyses will elucidate the complex regulatory networks and the diversity of proteins involved in resistance and susceptibility.

Identification of Microsatellite Markers Linked with Genomic Regions Involved in Resistance to Basal Stem Rot Disease Isolates in Oily Sunflower (Helianthus annuus L.) under Controlled Conditions
Sunflower (Helianthus annuus L.) is an important crop that its oil has nutritional and high economic value. Basal stem rot, caused by Sclerotinia sclerotiorum and S. minor, is one of the important and devastating disease of sunflower. The use of resistant cultivars is considered as the most important and effective method to control the disease. In this study, the reaction of 100 oily sunflower ...
متن کاملDoes genomic selection have a future in plant breeding?
Plant breeding largely depends on phenotypic selection in plots and only for some, often disease-resistance-related traits, uses genetic markers. The more recently developed concept of genomic selection, using a black box approach with no need of prior knowledge about the effect or function of individual markers, has also been proposed as a great opportunity for plant breeding. Several empirica...

Introgression of novel genetic variation into breeding populations is frequently required to facilitate response to new abiotic or biotic pressure. This is particularly true for the introduction of host pathogen resistance in plant breeding. However, the number and genomic location of loci contributed by donor parents are often unknown, complicating efforts to recover desired agronomic phenotyp...

Powdery mildew caused by Erysiphe cichoracearum is an important fungal disease which threatens tobacco (Nicotiana tabacum L.) production. The objective of this study was to determine DNA markers linked to genomic regions associated with resistance to powdery mildew in tobacco through the association mapping approach. Seventy tobacco geno-types were fingerprinted using 26 simple se-quence repeat...
متن کاملSunflower Hybrid Breeding: From Markers to Genomic Selection
In sunflower, molecular markers for simple traits as, e.g., fertility restoration, high oleic acid content, herbicide tolerance or resistances to Plasmopara halstedii, Puccinia helianthi, or Orobanche cumana have been successfully used in marker-assisted breeding programs for years. However, agronomically important complex quantitative traits like yield, heterosis, drought tolerance, oil conten...
