miRNAs as a Secret Weapon in the Battlefield of Haustoria, the Interface between Parasites and Host Plants

摘　　要：Parasitic plants have evolved independently 12 or 13 times and comprise about 1% of angiosperms. Depending on whether photosynthesis is at least partly retained or completely lost, plant parasites can be classified as hemi- and holoparasites, respec- tively. Facultative parasitic plants can survive and reproduce without any hosts, whereas obligate parasites cannot complete their life cycle without a host. All parasitic plants have a unique multicellular organ, haustorium （from Latin ＂haurire＂, meaning to drink）. Depending on where in the host a parasite inserts its haustoria, it can be categorized as a shoot/stem or root parasite. The most well-known parasitic p^ants include those in the genera Striga （witchweed）, Orobanche and the closely related Pheli- panche （broomrape）, and Cuscuta （dodders）,Parasitic plants have evolved independently 12 or 13 times and comprise about 1% of angiosperms.
