Hydrotropism and root-system development in arabidopsis
The gene MIZU-KUSSEI 1 (MIZ1) has been shown to regulate root hydrotropism in Arabidopsis thaliana, but its role in plant growth and survival under natural

Variation and evolution of herkogamy in Exochaenium
The spatial separation of stigmas and anthers (herkogamy) functions to reduce self-pollination and avoid interference between pollen dispersal and receipt. Little is known about the

Nodulation in the crotalarioid Lotononis s.l. clade (Research in Context)
Comparatively few studies have examined nodulation or rhizobial association in the basal legume tribe Crotalarieae. Within the Lotononis s. l. clade, Ardley et al. characterize the

Floral ontogeny and gene protein localization in mapaniid sedges
Poorly known, mapaniid sedges (Cyperaceae, subfamily Mapanioideae) possess unique floral forms, markedly different from stereotypical monocots, and the evolutionary issues of how or why this has
