What type of gene was suppressed in the tomato?
What type of gene was suppressed in the tomato?
Using this system, we suppressed the PDS, CTR1 and CTR2 genes in tomato. Suppression of CTR1 led to a constitutive ethylene response phenotype and up-regulation of an ethylene response gene, CHITINASE B. This phenotype is similar to Arabidopsis ctr1 mutant plants.
What is gene for gene resistance in plants?
Active plant defense, also known as gene-for-gene resistance, is triggered when a plant resistance (R) gene recognizes the intrusion of a specific insect pest or pathogen. Activation of plant defense includes an array of physiological and transcriptional reprogramming.
What causes genetic resistance?
Genetic resistance is when the daughter cell differs from the parental cell by a genetic event (following a mutation or horizontal acquisition of genetic information).
What kind of genes are used in tomato plants?
An exciting recent development in the UF/IFAS tomato breeding program has been the discovery of the Ty-6 resistance gene, a gene that is being widely used commercially and provides resistance against a broad range of begomoviruses.
How is breeding for resistance to tomato diseases?
This review focuses on the current status and promise of breeding for resistance to four major bacterial diseases including bacterial canker, bacterial speck, bacterial spot, and bacterial wilt because they are the most devastating bacterial diseases in China. 2. Bacterial canker
Are there any tomato plants that are resistant to bacterial diseases?
However, almost no commercial cultivars currently growing in the country are resistant to these four bacterial diseases because little effort has been devoted to breeding for resistance.
Which is homozygous for tomato yellow leaf curl disease?
CLN2777G is homozygous for resistance genes Bwr-12 (bacterial wilt), Ty-2 (tomato yellow leaf curl disease), and Tm22 (TMV). G2-6-20-15B is homozygous for Ty-3 (tomato yellow leaf curl disease resistance).
