Trans-specific gene silencing between host and parasitic plants.

Species of Orobanchaceae parasitize the roots of nearby host plants to rob them of water and other nutrients. Parasitism can be debilitating to the host plant, and some of the world's most pernicious agricultural pests are parasitic weeds. We demonstrate here that interfering hairpin constructs transformed into host plants can silence expression of the targeted genes in the parasite. Transgenic...

Trans-specific gene silencing of acetyl-CoA carboxylase in a root-parasitic plant.

Parasitic species of the family Orobanchaceae are devastating agricultural pests in many parts of the world. The control of weedy Orobanchaceae spp. is challenging, particularly due to the highly coordinated life cycles of the parasite and host plants. Although host genetic resistance often provides the foundation of plant pathogen management, few genes that confer resistance to root parasites ...

Allele-Specific Gene Silencing

Cardiac arrhythmias are a major healthcare problem in the developed world. The American Heart Association 2017 statistical report indicates that atrial fibrillation, the most common cardiac rhythm disorder, has an ≈25% lifetime incidence and annual costs of ≈26 billion dollars, whereas sudden cardiac death (usually caused by malignant arrhythmias) affects fewer individuals (just under 200 000 A...

Tomato and Tobacco Phytoene Desaturase Gene Silencing by Virus-Induced Gene Silencing (VIGS) Technique

Background and Aims: Virus-Induced Gene Silencing (VIGS) is a virus vector technology that exploits antiviral defense mechanism. By infecting plants with recombinant viruses containing host genes inserted in the viral genome, VIGS achieves the RNA silencing process. The purpose of this study was to investigate the possibility of tomato (Lycopersicon esculentum Mill.) and tobacco (Nicotiana be...

Host-specific races in the holoparasitic angiosperm Orobanche minor: implications for speciation in parasitic plants.

BACKGROUND AND AIMS Orobanche minor is a root-holoparasitic angiosperm that attacks a wide range of host species, including a number of commonly cultivated crops. The extent to which genetic divergence among natural populations of O. minor is influenced by host specificity has not been determined previously. Here, the host specificity of natural populations of O. minor is quantified for the fir...
