“…Negative infl uence on the raw material quality is also shown for some other viruses. It was discovered that AMV reduces the essential oil secretion in the lavender plants [71], Peppermint stunt virus -in the mint plants [72] and BBWV-1 reduces quantitative and qualitative content of essential oil in the Thymus vulgaris [73] and Salvia sclarea plants [74,75]. A decrease of the basic BAS in the infected plants is discovered also for ginseng (Panax ginseng C.A.…”

Viral diseases became an actual problem in medicinal plants cultivation. The number of viruses known to infect purple conefl ower increased signifi cantly in the last years in many countries. However, there is no any review about the viral diseases of this valuable medicinal crop. Therefore, the aim of this article is to summarize the main information about the viruses affecting purple conefl ower plants (Echinacea purpurea L. Moench.). An analysis of the literature data showed that purple conefl ower could be infected by 10 viruses. These viruses belong to the families Bromoviridae, Bunyaviridae, Secoviridae, Potyviridae, Vir ga vi ri dae, and almost all of them are considered to be highly harmful plant viruses. Additionally, four of them (TMV, TSWV, CMV, PVY) are in the top 10 of the most economically important plant viruses in the world and occupy the fi rst places. The data from a few countries show that the viral diseases of purple conefl ower are becoming more severe from year to year. The appearance of new viruses is registered on conefl ower every year that complicates prognosis and risk estimation of epiphytoties in these regions which, for example, were revealed in Bulgaria, Lithuania and Ukraine. This review presents the detailed symptoms of the viral diseases in purple conefl ower, the main properties of each virus and data about their harmful effect on the plant metabolism and on the quality of raw material (the concentration of biologically active substances and heavy metals in plants). K e y w o r d s: purple conefl ower, plant viruses, species diversity, biologically active substances, hea vy metals.

SUMMARYA survey was conducted in 2012 and 2013 to detect the presence and distribution of Alfalfa mosaic virus (AMV) in lavandin crops growing in continental parts of Croatia. A total of 73 lavandin samples from six crops in different localities were collected and analyzed for the presence of AMV and Cucumber mosaic virus (CMV) using commercial double-antibody sandwich (DAS)-ELISA kits. AMV was detected serologically in 62 samples collected at three different localities, and none of the samples tested positive for CMV. For further analyses, six selected samples of naturally infected lavandin plants originating from different localities were mechanically transmitted to test plants: Chenopodium quinoa, C. amaranticolor, Nicotiana benthamiana and Ocimum basilicum, confirming the infectious nature of the disease. Molecular detection was performed by amplification of a 751 bp fragment in all tested samples, using the specific primers CP AMV1/CP AMV2 that amplify the part of the coat protein (CP) gene and 3'-UTR. The RT-PCR products derived from the isolates 371-13 and 373-13 were sequenced (KJ504107 and KJ504108, respectively) and compared with the AMV sequences available in GenBank. CP sequence analysis, conducted using the MEGA5 software, revealed that the isolate 371-13 had the highest nucleotide identity of 99.5% (100% amino acid identity) with an isolate from Argentina originating from Medicago sativa (KC881010), while the sequence of isolate 373-13 had the highest identity with an Italian AMV isolate from Lavandula stoechas (FN667967) of 98.6% (99% amino acid identity). Phylogenetic analysis revealed the clustering of selected isolates into four molecular groups and the lavandin AMV isolates from Croatia grouped into two distinct groups, implying a significant variability within the AMV lavandin population.

“…A comparative analysis of essential oil yields from fresh aerial parts of Lavandula hybrida "Alardi" (Lamiaceae) showed that AMV (Alfalfa mosaic virus) infection reduced the volatile oil fraction by 36%, with a net decrease in monoterpene content accompanied by a 50% increase in sesquiterpenes [12].…”

Ocimum basilicum L., popularly known as sweet basil, is a Lamiaceae species whose essential oil is mainly composed of monoterpenes, sesquiterpenes and phenylpropanoids. The contents of these compounds can be affected by abiotic and biotic factors such as infections caused by viruses. The main goal of this research was an investigation of the effects of viral infection on the essential oil profile of common basil. Seeds of O. basilicum L. cv. Genovese were sowed and kept in a greenhouse. Plants presenting two pairs of leaves above the cotyledons were inoculated with an unidentified virus isolated from a field plant showing chlorotic yellow spots and foliar deformation. Essential oils of healthy and infected plants were extracted by hydrodistillation and analyzed by GCMS. Changes in essential oil composition due to viral infection were observed. Methyleugenol and p-cresol,2,6-di-tert-butyl were the main constituents. However, methyleugenol contents were significantly decreased in infected plants.
