Tobamoviruses are mechanically transmitted plant viruses that cause severe economic damage to vegetable and ornamental crops in Florida and worldwide. While certain tomato cultivars have genetic resistance to the most common tobamoviruses, no commercial tomato cultivars are resistant to tomato brown rugose fruit virus (ToBRFV), a recently described tobamovirus that also infects pepper and eggplant. It is currently unknown how ToBRFV may affect tomato production in Florida. This new 5-page publication of the UF/IFAS Plant Pathology Department describes symptoms of the virus, how it is different from other tobamoviruses, and how it is transmitted, as well as what to do if you think you have ToBRFV in your field.

Viral diseases are an important limiting factor in many crop production systems. Because antiviral products are not available, control strategies rely on genetic resistance or hygienic measures to prevent viral diseases, or on eradication of diseased crops to control such diseases. Increasing international travel and trade of plant materials enhances the risk of introducing new viruses and their vectors into production systems. In addition, changing climate conditions can contribute to a successful spread of newly introduced viruses or their vectors and establishment of these organisms in areas that were previously unfavorable. Tomato is economically the most important vegetable crop worldwide and many viruses infecting tomato have been described, while new viral diseases keep emerging. Pepino mosaic virus is a rapidly emerging virus which has established itself as one of the most important viral diseases in tomato production worldwide over recent years. Begomovirus species and other whitefly-transmitted viruses are invading into new areas, and several recently described new viruses such as Tomato torrado virus and new Tospovirus species are rapidly spreading over large geographic areas. In this article, emerging viruses of tomato crops are discussed.

Amount Of Knowledge

Potyviruses (viruses in the genus Potyvirus, family Potyviridae) constitute the largest group of known plant-infecting RNA viruses and include many agriculturally important viruses that cause devastating epidemics and significant yield losses in many crops worldwide. Several potyviruses are recognized as the most economically important viral pathogens. Therefore, potyviruses are more studied than other groups of plant viruses. In the past decade, a large amount of knowledge has been generated to better understand potyviruses and their infection process. In this review, we list the top 10 economically important potyviruses and present a brief profile of each. We highlight recent exciting findings on the novel genome expression strategy and the biological functions of potyviral proteins and discuss recent advances in molecular plant–potyvirus interactions, particularly regarding the coevolutionary arms race. Finally, we summarize current disease control strategies, with a focus on biotechnology-based genetic resistance, and point out future research directions. Expected final online publication date for the Annual Review of Phytopathology, Volume 59 is August 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Tomato Cultivars

Increasing fruit yield and quality of tomatoes under organic low-input conditions remains a challenge for producers and breeders. Therefore, it is necessary to identify superior tomato cultivars that are suitable for production and use as parents in breeding programmes. In the present study, the variations in plant morphology and fruit quality characteristics of tomato cultivars were assessed to reveal the traits associated with improved yield and fruit quality. Sixty diverse tomato cultivars were screened in 2015, and in 2016, a subset of 20 cultivars was selected for further evaluation under organic low-input conditions. The results showed high variability among cultivars in all 28 traits that were observed. Salad cultivars had lower plant growth and fruit quality (minerals, dry matter, total soluble solids, and total phenolics) by 10–70%, but they displayed 10–60% higher fruit yield and leaf minerals than cocktail cultivars. Salad tomato cultivars with superior yield and harvest index were mainly derived from breeding for intensive indoor production. Cocktail cultivars with superior yield were mainly derived from organic and outdoor breeding programs. There was a trade-off between fruit yield and quality, indicating a challenge for simultaneous improvement of yield and quality. The importance of Mg was highlighted because of its contribution to the fruit mineral concentration and fruit quality. Cultivars superior in one trait or trait combination under organic low-input conditions were identified to be used by producers and breeders as superior cultivars to meet their production targets and breeding objectives. The importance of Mg provides a novel path for further research on improving soil-available Mg in organic tomato production to enhance fruit mineral concentration and fruit quality in general.

Viruses and viroids are submicroscopic infectious particles which can cause disease symptoms on grapevine. These parasites are depending completely on the energy metabolism of the plant cell. To enter the host cell plant viruses depend on injuries or on transmission via invertebrates (insects, nematodes, etc.). Viruses are classified by many characters including particle morphology, host range and information content of the genome. At present about 70 viruses including 7 viroids infecting grapevine are known. In single or mixed infections they are potentially detrimental to the quality and quantity of grape production in any growing area of the world. Some viruses can cause severe economic damage in vineyards. In Hungary many important viruses and viroids have been detected in grape. This review summarises characteristics of viruses and the results of detection and characterization of virus and virus like diseases of grapevine in Hungary. The identification of the causal agent, its transmission, geographical distribution and the development of the diagnostic methods are also discussed.

Control Version

Tomato (Solanum lycopersicum L.) is one of the most cultivated crops in the world, offering many opportunities for research and marketing also. High productions, in conditions of economic sustainability and assured food safety, can only be achieved through the rational use of cultivation technologies, irrigation, fertilization and use of some cultivars with potential genetically performances. To achieve this goal, the present experiment focused on studying the influence of four tomato cultivars (Siriana F1, Minaret F1, HTP F1 and Inima de bou), in two irrigation regimes (5200 respectively 7800 m3) under chicken drops fertilizer compared with a non-fertilized control. The treatments used induced the increase of the fruit number per plant, ranging from 18 to 65%, statistically significant results (p<0.05) being obtained with the organic fertilizer on Minaret cultivar and the higher water quantity, compared to the control version. The highest production was obtained in the HTP F1 cultivars under organic fertilization and 7800 m3/ha irrigation.

Tomato Cultivars

A collection of 471 isolates of Fusarium oxysporum was obtained from symptomless tomato roots of plants grown at eight locations in Louisiana. Isolates that produced nitrate metabolism mutants (317 isolates) were included in an analysis of vegetative compatibility groups. One hundred and eighty-six isolates were assigned to 48 vegetative compatibility groups (2015–2062) containing 2–15 members from one to three different collection sites. Even though each site contained sub-populations of F. oxysporum common to other sites, only about half of the vegetative compatibility groups (21 groups) contained isolates from more than one site. In addition, there were 131 isolates of F. oxysporum that formed single-member vegetative compatibility groups. This diverse population composition is probably the result of several factors, including breeding strategies for resistance to fusarium wilt and tomato production practices in Louisiana. Resistance genes and horticultural traits from several sources (Lycopersicon spp.) have been incorporated into commercial tomato cultivars currently being grown. In addition, the long growing season in Louisiana allows several tomato cultivars containing different genes for resistance to be grown consecutively in the same field in a single year. Furthermore, other vegetable crops may be alternated with the tomato crops. Thus, the selection pressures that influence the composition of the nonpathogenic populations of F. oxysporum are in a constant state of flux. Key words: Fusarium oxysporum, genetic diversity, nonpathogens, vegetative compatibility groups.
