Landscape genetics of plants is an important research direction of the newly emerged interdisciplinary landscape genetics, which lags behind that of animals. These studies are increasingly important for the conservation of biodiversity and reserve management. This article briefly summarizes the major advances in plant landscape genetics in the past ten years form two aspects:the effects of landscapes on migration, dispersal, and gene flow measured by neutral genetic variation; and the interaction between the environment and adaptive genetic variation in natural populations and individuals. In addition, it compares landscape genetics of plants with that of animals through different study designs and analytical approaches. Due to the complexity of plant dispersal, landscape elements and analytical approaches are not generally considered in landscape genetics studies. For example, the least cost path analysis, popular in animal studies, is rarely used in plant studies. Furthermore, this article elucidates five problems in current studies of plants:(1) many studies lack an explicit research design for evaluating the effect of landscape pattern on genetic structure; (2) genetic structure is often analyzed with regard to contemporary landscapes, but it may reflect historical landscapes; (3) misleading results could be produced when limited loci are matched roughly to a combination of environmental variables; (4) studies on gene flow and adaptation have not yet been combined; and(5) many statistical methods could be inappropriate for landscape genetics. Plant landscape genetics studies should focus on solving these problems in the future and move from the description of spatial genetic structure to quantifying and predicting the effect of landscape pattern on genetic variation.
