“…These findings are consistent with those of Ref. [ 43 ], who stated that sequencing analyses revealed that FMV and FLMaV-1 Spanish isolates shared 89–93% identity with other Mediterranean isolates of the same viruses reported in the GenBank database. On the other hand, Ref.…”

Fig mosaic disease (FMD) is a viral disease that poses a significant danger to Egypt’s fig-producing economy. During the two growing seasons 2017 and 2018, fig leaves and fruits displaying a variety of symptoms linked with fig mosaic disease (FMD) were collected and differentiated from the most famous fig-growing governorates in Egypt, Mersa Matruh, Ismailia, and Giza. Symptomatic samples were tested for the presence of fig mosaic virus (FMV), fig leaf mottle-associated virus 1 (FLMaV-1), fig leaf mottle-associated virus 2 (FLMaV-2), fig mild mottle-associated virus (FMMaV), fig latent virus 1 (FLV-1), fig fleck-associated virus (FFkaV), and fig cryptic virus (FCV) using reverse transcription-polymerase chain reaction (RT-PCR) with specific primers. Three viruses were detected in mixed infections and showed positive results. FMV was detected with infection rate 49% followed by FLMaV-2 with infection rate 21.8% and FLMaV-1 with infection rate 10.9%, respectively, whereas all tested samples were negative for the other viruses. According to the sequence and phylogenetic analysis, the Egyptian FMV isolate was closely related to other FMV isolates, particularly the Argentina ones (Acc. No. KP796424), with 99% identity. While FLMaV-1 showed more than 98% identity with reference isolate FLMaV-1 (Acc. No. LN873219), on the other hand, the isolate of FLMaV-2 showed 100% identity with reference FLMaV-2 isolate (Acc. No. FJ473383) based on phylogenetic analysis. Because fig output in Egypt is expanding, our findings suggest that greater attention should be paid to improving the phytosanitary condition of fig trees in Egypt.

“…Both the percentage occurrence and distribution of FFkaV were similar to that of FMV, and the high percentage occurrence (79.3%) in symptomatic samples and low incidence (23.5%) in asymptomatic samples indicates an association between these viruses. However, the percentage occurrence of FFkaV in diseased samples was significantly lower in previous studies (Alfaro-Fernández et al 2014;El Air et al 2015). More research is therefore needed to investigate the relationship between FFkaV and FMD.…”

The common fig (Ficus carica L.) was one of the earliest horticultural crops to be domesticated. A number of different viruses can infect fig trees including Fig mosaic virus (FMV) that has been detected in several commercial fig trees in Xinjiang, China. However, the distribution of FMV and other fig-infecting viruses in China remains unknown. In the present study, a sample from an ancient fig tree growing in Xinjiang was investigated by electron microscopy (EM) followed by PCR/RT-PCR, and FMV, Fig badnavirus 1 (FBV-1) and Fig leaf mottle-associated virus 1 (FLMaV-1) were detected. Fig leaf samples (252) from commercial orchards across China were also subjected to PCR/RT-PCR, and FMV, FBV-1 and Fig fleck-associated virus (FFkaV) were relatively abundant (44.4, 48.4 and 44%, respectively), while FLMaV-1 and Fig mild mottle-associated virus (FMMaV) were much scarcer (5.6 and 0.4%, respectively), and FLMaV-2, Fig cryptic virus (FCV), and Fig latent virus (FLV) were not detected. The presence of disease-causing viruses in fig trees presents a significant challenge for fig producers in China. This study may help to promote actions aimed at controlling fig viruses, especially FMV.
