Abstract

Thirty-seven Capsicum accessions containing cultivated and wild species were screened for resistance to Cucumber mosaic virus (CMV), and were also investigated for their response to Tomato aspermy virus (TAV), Tomato mosaic virus (ToMV), Pepper mild mottle virus (PMMoV), and Tomato spotted wilt virus (TSWV). C. baccatum PI 439381-1-3 (PI 439381-1-3), C. frutescens LS 1839-2-4 (LS 1839-2-4), and C. frutescens cv. Tabasco (cv. Tabasco) showed a hypersensitive reaction against CMV-Y, and thus were not systemically infected. Only inoculated leaves of C. annuum cv. Sapporo-oonaga and cv. Nanbu-oonaga were infected with CMV-Y, and viral infection did not spread systemically. These five accessions (PI 439381-1-3, LS 1839-2-4, cv. Tabasco, cv. Sapporo-oonaga, and cv. Nanbu-oonaga) were considered resistant to CMV-Y. These accessions were also resistant to other CMV isolates, but not to the TAV isolate. PI 439381-1-3, LS1839-2-4, cv. Sapporo-oonaga, and cv. Nanbu-oonaga were susceptible to PMMoV, while PI 439381-1-3 and LS1839-2-4 showed systemic necrosis. All CMV-resistant accessions were susceptible to TSWV. Field tests of eight Capsicum accessions, including CMV, PMMoV, and/or TSWV-resistant accessions, demonstrated that most of the ...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
