在许多微生物病原体中，光代表着调节毒力的信号。以油桃和樱桃两种核果为试材，研究了光照对松材线虫褐腐病的影响。将3个单孢子菌株接种于油桃上，分别在白光、红光、蓝光、绿光和黑光下分两个光周期进行培养。此外，为了了解日光照射对樱桃褐腐病的影响，在不同樱桃品种上接种了松茸，并在两种模拟日照下进行了培养。接种油桃在58 W白光和12小时光照/12小时黑暗中培养，其病情严重程度和产孢量显著高于在连续黑暗中培养的油桃。与在白光下培养的果实相比，只有红光能显著增加接种这三种松散支原体的油桃的发病率和严重程度。高光强(185.45 W/m2)对所有早熟品种和晚熟品种的褐腐病严重程度均高于低光强(145.85 W/m2)。在强光下接种樱桃后，M1PNL2基因的表达显著上调，特别是在晚樱桃品种中，而MlPG1基因的表达在不同的光照度下没有任何变化。
Light represents a signal for the regulation of virulence in many microbial pathogens. Two stone fruits, nectarines and cherries, were used to investigate the influence of light on brown rot caused byMonilinia laxa. Three single‐spore isolates were inoculated on nectarines and incubated under different white lights, red light, blue light, green light, and black light with two photoperiods. In addition, to understand the effect of daylight irradiance on brown rot,M.laxawas inoculated on different cherry cultivars and incubated under two simulated solar irradiations. Significantly higher disease severity and sporulation were reported on inoculated nectarines incubated under 58 W white light for 12 hr light/12 hr darkness than on nectarines incubated in continuous darkness. Only red light caused a significant increase in the incidence and severity of the disease in nectarines inoculated with the threeM.laxaisolates, compared to fruit incubated under white light. High light intensity (185.45 W/m2), caused greater brown rot severity in all cherry cultivars, both early and late varieties, than low irradiance (145.85 W/m2). Significant up‐regulation of the pathogenicity‐relatedMlPNL2gene was observed as an early response after cherry inoculation under high‐intensity light, especially in late cherry cultivars, whileMlPG1expression did not show any changes under different light irradiances.M. laxawas shown to be a light‐responsive fungal pathogen, and light seemed to play an active role in brown rot development.
