Three cultivars of pea did not differ in their susceptibility to Cucumber Mosaic Virus (CMV) notwithstanding the age of the inoculated plants. But their susceptibility to infection with Bean Yellow Mosaic Virus (BYMV) differed. Horse bean cultivars 'Nadwiślański' and 'Major' proved to be less susceptible to Broad Bean True Mosaic Virus (BBTMV) when older plants were-inoculated. Two bean cultivars 'Złota Saxa' and 'Earle' appeared to be susceptible to BBTMV only in the phase of developing primary leaves and the age-dependent resistance to infection increased faster in plants of the cv. 'Złota Saxa'. Both cultivars of bean showed also age-dependent resistance to infection by BYMV. All these viruses restricted growth and yield of plants. The decreases were greater when younger plants were inoculated. These dependences appeared most distinctly in pea cv. 'Sześciotygodniowy' infected with CMV and in two cultivars of bean infected with BYMV.

AbstractBroad bean (Vicia faba L) is the fourth most important pulse crop in the world. In Argentina, broad bean production was of 1,841 hectares and 16,500 tons during the 2017 growing season. Broad bean is commonly used in rotations; especially by farmers located in “green belts” that are peri-urban areas surrounding large cities that include horticultural family farms. Plants showing marked foliar mosaic symptoms, typical of viral infection, were collected during the 2015 growing season in the green belt of Córdoba city, Argentina. Preparations of symptomatic tissues were mechanically inoculated onto healthy broad bean plants in the greenhouse, which developed symptoms similar to those observed in the field. In addition, symptomatic samples were positive when tested by indirect ELISA with the anti-potyvirus group monoclonal antibody. Further, flexuous filamentous particles typical of potyviruses were observed under the electronic microscope on dip preparations. Lastly, total RNA was extracted from a symptomatic leaf and high-throughput sequenced, which allowed the assembly of a single virus sequence corresponding to a new highly divergent strain of Bean yellow mosaic virus (BYMV). Phylogenetic insights clustered this Argentinean broad bean isolate (BYMV-ARGbb) within group IX of BYMV. Given the economical importance of this virus and its associated disease, the results presented here are a pivotal first step oriented to explore the eventual incidence and epidemiological parameters of BYMV in broad bean in Argentina.

A pea mosaic strain and a bean strain of bean yellow mosaic virus (BYMV) were isolated from naturally infected pea and broad bean plants and named BYMV-Ps and BYMV-Vf, respectively. A third strain of BYMV isolated from Gladiolus (BYMV-G) was obtained from Denmark which was distinguished from the two above strains serologically and by its symptoms in test plants. BYMV-Ps and BYMV-Vf caused yellow mosaic symptoms and green mosaic symptoms, respectively, in eight pea cultivars tested, but the concentration of BYMV varied among the cultivars. BYMV-G caused mild mosaic or vein clearing in peas. A need to improve resistance to BYMV in the Finnish pea varieties was recognized.

Duration Of Infection

Efficiency of bean yellow mosaic virus (BYMV) transmission from broad bean source plants varied with age of leaf on which aphids, MYZU8 persicae (Sulz.), fed. Duration of infection in the source plants did not affect transmission. Observations of acquisition feeding behaviour yielded results which are interpreted to indicate that most transmission occurs with virus acquired intracellularly.

The composition of crystalline inclusions and dense bands in cells of broad bean leaves infected with bean yellow mosaic virus was studied by differential enzymatic digestion. Frozen thick sections were prefixed in glutaraldehyde and exposed to proteinases and nucleases, after which ultrathin sections were prepared for electron microscopy. Examination revealed that the crystals were completely digested by pepsin in 30 min, whereas the dense bands remained intact for the first 20 min, and could not be found after longer periods of digestion. When ultrathin sections of tissues embedded in glycol methacrylate were incubated with the enzymes, pepsin digested the crystals; this left only a filamentous residue which did not disappear after further exposure to pepsin or to RNase. Trypsin had the same effect, but was slower and less consistent. The dense bands were entirely digested in thin sections by pepsin and trypsin. Neither inclusion was affected by RNase or DNase in thick or thin sections. These results demonstrate that the crystals and dense bands are composed entirely or primarily of protein, but there is no evidence that they contain nucleic acid.
