Phylogenetic reconstructions of diverse tropical groups have yielded biological insights that extend well beyond the field of systematics, illuminating such topics as biome assembly and plant–insect coevolution. In this issue of New Phytologist, De-Nova et al. (pp. 276–287) present a rigorous time-calibrated phylogeny of the Neotropical tree genus Bursera in order to estimate lineage ages, and ...

In models of economic geography, plant-level scale economies and trade costs create incentives for spatial agglomeration of production into a manufacturing core and agricultural periphery, creating regional income differentials. We examine tax competition between national governments to influence the location of manufacturing activity. Labour is imperfectly mobile and governments impose redistr...

Three isolates of Bean yellow mosaic virus (BYMV) from the Czech Republic originating from gladiolus plants were examined according to their biological and molecular characteristics. Partial sequence of coat protein-nuclear inclusion protein b (CP-NIb) coding region (768 bp) of these isolates were determined and compared with the corresponding sequences of different BYMV isolates obtained from ...
