During the course of the development of nitrogen-fixing root nodules induced by Sinorhizobium meliloti on the model plant Medicago truncatula, tubules called infection threads are cooperatively constructed to deliver the bacterial symbiont from the root surface to cells in the interior of the root and developing nodule. Three-dimensional reconstructions of infection threads inside M. truncatula nodules showed that the threads formed relatively simple, tree-like networks. Some characteristics ...

Auxin and ethylene response interactions during Arabidopsis root hair development dissected by auxin influx modulators
Plant Physiology ; The plant hormones auxin and ethylene have been shown to play important roles during root hair development. However, cross talk between auxin and ethylene makes it difficult to understand the independent role of either hormone. To dissect their respective roles, we examined the effects of two
Molecular Cloning and Characterization of [beta]-Expansin Gene Related to Root Hair Formation in Barley1
Plant Physiology ; Root hairs are specialized epidermal cells that play a role in the uptake of water and nutrients from the rhizosphere and serve as a site of interaction with soil microorganisms. The process of root hair formation is well characterized in Arabidopsis (Arabidopsis thaliana); however, there is a very
Roles of Phosphatidylinositol 3-Kinase in Root Hair Growth1[OA]
Plant Physiology ; The root hair is a model system for understanding plant cell tip growth. As phosphatidylinositol 3-phosphate [PtdIns(3)P] has been shown in other plant cell types to regulate factors that affect root hair growth, including reactive oxygen species (ROS) levels, cytoskeleton, and endosomal movement,
Nod factor-induced root hair curling: Continuous polar growth towards the point of nod factor application1
Plant Physiology ; A critical step in establishing a successful nitrogen-fixing symbiosis between rhizobia and legume plants is the entrapment of the bacteria between root hair cell walls, usually in characteristic 180[degrees] to 360[degrees] curls, shepherd's crooks, which are formed by the host's root hairs.
SOS4, a pyridoxal kinase gene, is required for root hair development in Arabidopsis
Plant Physiology ; SOS4, A Pyridoxal Kinase Gene, Is Required for Root Hair Development in Arabidopsis1 Root hair development in plants is controlled by many genetic, hormonal, and environmental factors. A number of genes have been shown to be important for root hair formation. Arabidopsis salt overly sensitive 4
