Capsicum Annuum L

Resistance of the Hungarian pepper (Capsicum annuum L.) cultivar "Gre.ygo" to Tohamoviruses has been investigated. All plants of the population of Greygo proved to be resistant to tobacco mosaic and tomato mosaic viruses (TMV, ToMV), both represent the pepper pathotypes Po of Tohamoviruses. Individuals of Greygo, however, were found to be susceptible to pathotypes P12 and P123 of pepper mild mottle virus (PMMV). When inoculated with the XM isolate of dulcamara yellow fleck virus (DYFV, pathotype P1) the population of Greygo segregated in resistant and susceptible plants. These results as well as inoculations of the progenies of three TMV resistant plants clearly showed, that besides the resistance allele Li the cultivar Greygo possesses also an another allele. This allele, provisionally marked by L2g behaves like to the allele L2 characteristic to Capsicum frutescens cv. . Tabasco. Determination of the identity of the allele L2g to the allele L2 needs further genetic and pathological informations. Relations between the Tohamoviruses pathogenic to pepper and the alleles of the resistance gene L are outlined for the discussion.

Aims: This study aimed to investigate the changes in antioxidant activity and protein content between non-infected and infected leaves of three Capsicum annuum varieties against Pepper veinal mottle virus. Materials and Methods: Pepper veinal mottle virus isolated from infected pepper plants was inoculated to three healthy varieties of pepper (Pepper Narval, Yolo Wonder and Chili pepper) by gently rubbing on the leaves of 14-day-old seedlings. Control peppers of each variety were treated in the same way with distilled water. The infection of inoculated plants was confirmed by the enzyme-linked immunosorbent assay method. Control and infected leaves were collected 21 days after inoculation (when symptoms manifested) and used for biochemical analyses. Change in different biochemical parameters (catalase, superoxide dismutase, malondialdehyde and protein) in infected pepper plant was observed compared to control non-infected ones. Results: Catalase and superoxide dismutase activities were increased in Pepper Narval and Pepper Yolo Wonder infected leaves compared to non-infected, while a significant decrease was observed in infected Chili pepper compared to control. Higher malondialdehyde content was found in Pepper Yolo Wonder and Chili pepper infected leaves (P < 0.05) than control while a non-significant difference was shown between the infected and non-infected of Pepper Narval variety (P > 0.05). Infected Chili pepper showed high protein content compared to control (P < 0.05). An opposite trend was observed in pepper Narval and Yolo Wonder varieties (P < 0.05). Conclusion: The results of this study showed that Pepper veinal mottle virus infection induces changes in antioxidant enzymes activities, malondialdehyde and total protein levels. These biochemical components were greatly expressed differentially between Pepper veinal mottle virus infected and non-infected in Pepper Yolo Wonder variety. Further studies with more biochemical parameters may contribute to improve the pepper tolerance mechanism to Pepper veinal mottle virus in a breeding program.
