Inheritance of resistance to Pepper yellow mosaic virus in Capsicum baccatum var. pendulum.
We investigated inheritance of resistance to Pepper yellow mosaic virus (PepYMV) in Capsicum baccatum var. pendulum accessions UENF 1616 (susceptible) crossed with UENF 1732 (resistant). Plants from generations P1, P2, F1, F2, BC1:1, and BC1:2 were inoculated and the symptoms were evaluated for 25 days. Subsequently, an area under the disease progress curve was calculated and subjected to gener...
متن کاملFIRST RECORD OF GENUS LEVEILLULA ON A MEMBER OF THE MORACEAE: Leveillula taurica ON Ficus carica
A powdery mildew fungus Leveillula taurica (Erysiphales) is reported for the first time on fig tree (Ficus carica) (Moraceae) in Sistan region, Iran. One hundred fungal organs including clistothecia, asci, ascospores and conidia, were micrometried by the calibrated Olympus BH2 microscope. All characters of the organs were recorded and drawn using a drawing tube. Conidiophores were with cylindri...
متن کاملLoss of Function in Mlo Orthologs Reduces Susceptibility of Pepper and Tomato to Powdery Mildew Disease Caused by Leveillula taurica
Powdery mildew disease caused by Leveillula taurica is a serious fungal threat to greenhouse tomato and pepper production. In contrast to most powdery mildew species which are epiphytic, L. taurica is an endophytic fungus colonizing the mesophyll tissues of the leaf. In barley, Arabidopsis, tomato and pea, the correct functioning of specific homologues of the plant Mlo gene family has been foun...
متن کاملDifferential resistances to anthracnose in Capsicum baccatum as responding to two Colletotrichum pathotypes and inoculation methods
Chili anthracnose, caused by Colletotrichum spp., is one of the major diseases to chili production in the tropics and subtropics worldwide. Breeding for durable anthracnose resistance requires a good understanding of the resistance mechanisms to different pathotypes and inoculation methods. This study aimed to investigate the inheritances of differential resistances as responding to two differe...
متن کاملMolecular Mapping of PMR1, a Novel Locus Conferring Resistance to Powdery Mildew in Pepper (Capsicum annuum)
Powdery mildew, caused by Leveillula taurica, is a major fungal disease affecting greenhouse-grown pepper (Capsicum annuum). Powdery mildew resistance has a complex mode of inheritance. In the present study, we investigated a novel powdery mildew resistance locus, PMR1, using two mapping populations: 102 'VK515' F2:3 families (derived from a cross between resistant parental line 'VK515R' and su...
