The plant root cap mediates the direction of root tip growth and protects internal cells. Root cap cells are continuously produced from distal stem cells, and the phytohormone auxin provides position information for root distal organization. Here, we identify the Arabidopsis thaliana auxin response factors ARF10 and ARF16, targeted by microRNA160 (miR160), as the controller of root cap cell formation. The Pro^sub 35S^:MIR160 plants, in which the expression of ARF10 and ARF16 is repressed, and...

	Extracellular Proteins in Pea Root Tip and Border Cell Exudates1[OA] Plant Physiology ; Newly generated plant tissue is inherently sensitive to infection. Yet, when pea (Pisum sativum) roots are inoculated with the pea pathogen, Nectria haematococca, most newly generated root tips remain uninfected even though most roots develop lesions just behind the tip in the region of elongation.
	The Onset of Gravisensitivity in the Embryonic Root of Flax1[OA] Plant Physiology ; Vertical orientation of emerging roots typically is the first response of plants to gravity. Although root gravitropism has been studied extensively, no conclusive data on the onset of gravisensing exist. We determined the inception of gravisensitivity in flax (Linum usitatissimum) roots by

	The roles of auxin response factor domains in auxin-responsive transcription Plant Cell ; Auxin response factors (ARFs) are transcription factors that bind to TGTCTC auxin response elements in promoters of early auxin response genes.
