True Seed Transmission of Sugarcane bacilliform virus (SCBV) in Sugarcane

Abstract A description is provided for Puccinia malvacearum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Althaea, Protex, Kitaibelia, Lavatera, Malva, Malvastrum, Malope, Sidalcea and a total of about 50 species in 10 genera of Malvaceae. DISEASE: Rust of hollyhock. GEOGRAPHICAL DISTRIBUTION: Worldwide. TRANSMISSION: Farlow (1886) reported the introduction of the pathogen into U.S.A. on seed of Malope sp. imported from Europe. However, it is doubtful whether true seed transmission occurs. Taubenhaus (1911) showed that teliospores, overwintering in soil on infected bracts and carpels in late autumn, remain viable for over four months and act as a source of infection of seed in the spring and that mycelium may also overwinter in a viable condition in young host shoots. The importation of the pathogen on plants introduced into New Zealand is recorded by Cunningham (1931: 154).

Virus Distribution

The establishment of a sweet potato repository in Georgia that will eventually accept and distribute true seed of sweet potato [Ipomoea batatas (L.) Lam.] raised the question of seed transmission of viruses, especially of sweet potato feathery mottle virus (SPFMV). Seedlings obtained from virus-infected parent plants were free of viral infection. Examination of virus distribution in virus-infected plants determined that SPFMV was present in vegetative tissue, but not in reproductive organs, indicating that the probability of SPFMV transmission in sweet potato through seed is very low.

Leaf Curl

Sweet potato leaf curl virus (SPLCV) threatens global sweet potato production. SPLCV is transmitted by Bemisia tabaci or via infected vegetative planting materials; however, SPLCV was suggested to be seed transmissible, which is a characteristic that is disputed for geminiviruses. The objective of this study was to revisit the validity of seed transmission of SPLCV in sweet potato. Using large-scale grow-out of sweet potato seedlings from SPLCV-contaminated seeds over 4 consecutive years, approximately 23,034 sweet potato seedlings of 118 genotype entries were evaluated. All seedlings germinating in a greenhouse under insect-proof conditions or in a growth chamber were free of SPLCV; however, a few seedlings grown in an open bench greenhouse lacking insect exclusion tested positive for SPLCV. Inspection of these seedlings revealed that B. tabaci had infiltrated the greenhouse. Therefore, transmission experiments were conducted using B. tabaci MEAM1, demonstrating successful vector transmission of SPLCV to sweet potato. Additionally, tests on contaminated seed coats and germinating cotyledons demonstrated that SPLCV contaminated a high percentage of seed coats collected from infected maternal plants, but SPLCV was never detected in emerging cotyledons. Based on the results of grow-out experiments, seed coat and cotyledon tests, and vector transmission experiments, we conclude that SPLCV is not seed transmitted in sweet potato.
