摘      要：Dear Editor, Plants secrete nectar to attract mutualistic animals, which predominantly function as pollinators, as in the case of flo- ral nectar, or defenders against herbivores, as in the case of extrafloral nectar （Nicolson et al., 2007）. Because nectars usu- ally represent aqueous solutions containing sugars and other nutrient metabolites （Baker and Baker, 1983）, they are sus- ceptible to infestation by microbial organisms, which can use the nectar-secreting tissues as entry sites to infect the plant. Nectar-secreting tissues thus require an efficient shield against pathogen infections. To date, our knowledge about the way that plants protect their nectar from microorganisms is rather limited. Several reports have focused on ＇defensive chemicals＇,
