“…Grey mould is caused by Botrytis cinerea , anamorph of Botryotinia fuckeliana , and has a significant economic impact on grape yields worldwide. There is currently a scarcity of scientific literature reporting crop losses caused by B. cinerea (Carisse, ). However, global yield losses of US$2 billion per annum have been reported (Elmer & Michailides, ).…”

Identification and characterization of Botrytis medusae, a novel cryptic species causing grey mould on wine grapes in Australia

In a collection of 735 Botrytis isolates sampled from Australian wine grape‐growing regions, a single isolate from clade I and group I (based on Bc‐hch RFLP analysis) was found. As many Botrytis species are known to live sympatrically, it was hypothesized that this isolate might be a new Botrytis species. After phenotypic and molecular assays supported this hypothesis, the species was designated B. medusae. Phylogenetic analyses using the nuclear genes G3PDH, HSP60, RPB2, NEP1 and NEP2 consistently placed B. medusae in an early‐diverging clade I Botrytis spp. lineage. Botrytis medusae produced white aerial mycelium, grew faster at 30 °C and produced long‐branched conidiophore extensions, compared with B. cinerea and B. pseudocinerea. Botrytis medusae was only able to infect wounded grape leaves and was significantly less virulent on wounded leaves and berries than B. cinerea. Botrytis medusae also lacked villiform appendages on the conidial surface and long conidiophores, which are defining features of B. sinoviticola and B. californica, respectively. Identification and characterization of new cryptic Botrytis species living in sympatry on grapevines could potentially provide information to assist disease management strategies for B. cinerea.

“…B. cinerea has no apparent host specificity and can infect more than 1000 plant species (Elad et al , ). The pathogen is found worldwide and causes disease in many fruit, flower and leafy vegetable crops (Boff, ; Carisse, ; Elad et al , ). B. cinerea is classified as a necrotroph, meaning that it prefers to infect and grow on damaged or senescing tissues, eventually causing tissue death.…”

Summary The fungal pathogen Botrytis cinerea causes grey mould, a commercially damaging disease of strawberry. This pathogen affects fruit in the field, storage, transport and market. The presence of grey mould is the most common reason for fruit rejection by growers, shippers and consumers, leading to significant economic losses. Here, we review the biology and epidemiology of the pathogen, mechanisms of infection and the genetics of host plant resistance. The development of grey mould is affected by environmental and genetic factors; however, little is known about how B. cinerea and strawberry interact at the molecular level. Despite intensive efforts, breeding strawberry for resistance to grey mould has not been successful, and the mechanisms underlying tolerance to B. cinerea are poorly understood and under‐investigated. Current control strategies against grey mould include pre‐ and postharvest fungicides, yet they are generally ineffective and expensive. In this review, we examine available research on horticultural management, chemical and biological control of the pathogen in the field and postharvest storage, and discuss their relevance for integrative disease management. Additionally, we identify and propose approaches for increasing resistance to B. cinerea in strawberry by tapping into natural genetic variation and manipulating host factors via genetic engineering and genome editing.

“…Based on phenotypical, ecological and genetic description, Botrytis cinerea is known as a highly variable species (Carisse, 2016 Therefore, in this study more than 270 Botrytis spp. samples from 12 different areas of Lithuania, collected in 2012-2014, were analysed to identify as B. cinerea.…”

“…The biology of the pathogen comprises a number of interactions between host, pathogen and environment which influence disease development (Carisse, 2016;Elad, 2016;Elad et al, 2016). The populations of B. cinerea are highly diverse and deeply structured according to the host plant and the cropping system (Walker, Fournier, 2013).…”

Botrytis cinerea Pers.: Fr is an important strawberry disease-causing pathogen with a broad host range. Classical B. cinerea identification is complicated due to the lack of morphological polymorphism between species. The use of molecular tools helps to identify pathogens fast and accurately. This study aimed to determine Botrytis spp. isolates and evaluate the genetic diversity of grey mould population in Lithuania. During June-August of 2012-2014, 273 isolates were sampled from 12 different areas of Lithuania. All samples were isolated from infected fruits, and single-spore isolates were extracted. B. cinerea isolates were identified using B. cinerea species-specific primers Bc108The polymerase chain reaction (PCR) showed two bands characteristic of two specific DNA fragments of B. cinerea -upper and lower band of 360 and 480 bp, respectively. These two bands reflect pathogen genotype differentiation and could be used for cryptic species detection. The cryptic species analysis revealed that resistant group I accounted for 16.95% and sensitive group II for 83.05% of the Lithuanian collection of B. cinerea isolates. The precise identification of the B. cinerea cryptic species is important for the species-specific fungicide resistance and aggressiveness. Four microsatellite markers used in this study revealed genetic diversity of B. cinerea. The 158 isolates were identified as B. cinerea. The most polymorphic microsatellite marker was BC6 (0.88) and the least polymorphic -BC7 (0.79). The isolates clustered into three genetic groups. The first group consisted of 45 strains, the second group of 15 and the third group of 4 isolates. Our data show genetic diversity within the Lithuanian population of B. cinerea. One of the management tools is recognition and identification of the pathogen which leads to optimal and efficient disease management.
