Host Genes

Pepper mottle virus (PepMoV) is a destructive pathogen that infects various solanaceous plants, including pepper, bell pepper, potato, and tomato. In this review, we summarize what is known about the molecular characteristics of PepMoV and its interactions with host plants. Comparisons of symptom variations caused by PepMoV isolates in plant hosts indicates a possible relationship between symptom development and genetic variation. Researchers have investigated the PepMoV–plant pathosystem to identify effective and durable genes that confer resistance to the pathogen. As a result, several recessive pvr or dominant Pvr resistance genes that confer resistance to PepMoV in pepper have been characterized. On the other hand, the molecular mechanisms underlying the interaction between these resistance genes and PepMoV-encoded genes remain largely unknown. Our understanding of the molecular interactions between PepMoV and host plants should be increased by reverse genetic approaches and comprehensive transcriptomic analyses of both the virus and the host genes.

Transmission of plant viruses by aphids involves multitrophic interactions among host plants, aphid vectors, and plant viruses. Here, we used small RNA (sRNA) sequencing to visualize the sRNA response of Myzus persicae to two plant viruses that M. persicae transmits in different modes: the nonpersistent Potato virus Y (PVY) versus the persistent Potato leafroll virus (PLRV). Aphids exposed to PLRV produced significantly less 22 mers aligned to the aphid genome, and an abundance of 26 to 27 mers, many of which were predicted to be piRNA. Additionally, expression of Buchnera aphidicola tRNA-derived sRNAs was influenced by PLRV and, to a lesser extent, PVY, suggesting that plant viruses alter the aphid-endosymbiont relationship. Finally, aphids exposed to PLRV-infected plants generated an abundance of unusually long sRNAs and a reduced number of 22 mers against an aphid virus, Myzus persicae densovirus (MpDNV) and had higher MpDNV titer. Expression of the PLRV silencing suppressor P0 in plants recapitulated the increase in MpDNV titer in the absence of PLRV infection. Our results show that plant viruses transmitted in two different modes cause distinct effects on their vector with regards to post-transcriptional gene regulation, symbiosis with Buchnera, and the antiviral immune response of aphids to an aphid-infecting densovirus.

The properties of a new filamentous virus found on yellow oat-grass (suggested name <I>Trisetum flavescens mosaic virus</I> – TFMV) were compared with those of the two potyviruses <I>Oat mosaic virus (</I>OMV) and <I>Oat necrotic mottle virus</I> (ONMV). The latter viruses were chosen because their host range, virus particles and some other characteristics are similar to TFMV. Mechanical transmission of TFMV to some OMV and ONMV host plants, drop precipitation, indirect-ELISA, DAS-ELISA, SSEM and RT-PCR were used in the study. However, there was no proof that TFMV is identical with OMV or ONMV. <I>Avena abyssinica</I> and <I>Bromus mollis</I> were found to be new experimental hosts of TFMV.&nbsp;

Productive Land

Widespread replacement of native ecosystems by productive land sometimes results in the outbreak of a native species. In New Zealand, the introduction of exotic pastoral plants has resulted in the diet alteration of the native coleopteran species, Costelytra zealandica (White) (Scarabaeidae) such that this insect has reached the status of pest. In contrast, C. brunneum (Broun), a close congeneric species, has not developed such a relationship with these ‘new’ host plants. This study investigated the feeding preferences and fitness performance of these two closely related scarab beetles to increase fundamental knowledge about the mechanisms responsible for the development of invasive characteristics in native insects. To this end the feeding preferences of larvae of both Costelytra species were investigated under controlled conditions and the survival and larval growth of the invasive species C. zealandica were compared on native and exotic host plants. Costelytra zealandica, when sampled from exotic pastures, was unable to fully utilise its ancestral native host and showed better performance on exotic plants. In contrast, C. zealandica sampled from native grasslands did not perform significantly better on either host and showed similar feeding preferences to C. brunneum. This study suggests the possibility of strong intra-specific variation, in the ability of C. zealandica to exploit native or exotic plants, supporting the hypothesis that such ability underpins the existence of distinct host-races in this species.

In a study to evaluate the potential of Vicia faba (faba bean) as a cover and forage crop for Florida, 60 accessions of faba bean with diverse genetic backgrounds and geographic origins were acquired from the USDA Germplasm Repository in Pullman, WA. The beans were grown south of Lake Okeechobee in Belle Glade, FL, from December 2000 to April 2001. Reddish-brown elliptical lesions first appeared on the leaflets of two of the faba bean plants 10 to 12 weeks after planting. Within 2 weeks of initial symptoms, a mosaic pattern was expressed on the newly emergent leaves of the same plants. After disease expression, new pods aborted, while developing pods became stunted, distorted, and blistered. Potyvirus cylindrical inclusions (CI) were found in leaf strips (1) of the original plants. Viral symptoms were expressed in manually inoculated plants of Chenopodium amaraticolor, C. quinoa, Lactuca sativa, Nicotiana benthamiana, Petunia × hybrida, Verbena × hybrida, Vicia faba, and Zinnia elegans. Inoculated species of Phaseolus and Pisum were not infected. The virus causing the disease was identified as Bidens mottle virus (2) based on host range, characteristic CI in Z. elegans, and homologous lines of precipitation in SDS-immunodiffusion using antiserum to Bidens mottle and a known antigen. Both the primary host of this virus Bidens mottle virus and its aphid vectors are ubiquitous throughout Florida. To our knowledge, this is the first report of Bidens mottle virus infecting a member of the Leguminosae. References: (1) R. G. Christie and J. R. Edwardson.
