Maize YABBY Genes drooping leaf1 and drooping leaf2 Regulate Plant Architecture.
Leaf architecture directly influences canopy structure, consequentially affecting yield. We discovered a maize (Zea mays) mutant with aberrant leaf architecture, which we named drooping leaf1 (drl1). Pleiotropic mutations in drl1 affect leaf length and width, leaf angle, and internode length and diameter. These phenotypes are enhanced by natural variation at the drl2 enhancer locus, including r...
متن کاملThe establishment of axial patterning in the maize leaf.
The maize leaf consists of four distinct tissues along its proximodistal axis: sheath, ligule, auricle and blade. liguleless1 (lg1) functions cell autonomously to specify ligule and auricle, and may propagate a signal that correctly positions the blade-sheath boundary. The dominant Wavy auricle in blade (Wab1) mutation disrupts both the mediolateral and proximodistal axes of the maize leaf. Wab...
متن کاملInduction in Maize
The maize ligule is an adaxial membranous structure on the leaf that develops at the boundary of the sheath and blade. The ligule and the associated auricle are dispensable structures, amenable to genetic manipulation. We present here a genetic analysis of ligulelessl ( lg l ) and liguleless2 (lg2), the two genes known to be uniquely necessary for ligule and auricle development. We show that bo...
متن کاملMosaic analysis of the dominant mutant, Gnarley1-R, reveals distinct lateral and transverse signaling pathways during maize leaf development.
Maize leaves are organized into two major domains along the proximal-distal axis: a broad flat blade at the distal end of the leaf, and a narrow, thickened sheath that encircles the stem. Between the blade and sheath are two wedge-shaped tissues called auricles, and the ligule, an epidermally derived fringe. Members of the Knotted1 (Kn1) family of mutations change the shape and position of both...
متن کاملThe extended auricle1 (eta1) gene is essential for the genetic network controlling postinitiation maize leaf development.
The maize leaf is composed of distinct regions with clear morphological boundaries. The ligule and auricle mark the boundary between distal blade and proximal sheath and are amenable to genetic study due to the array of mutants that affect their formation without severely affecting viability. Herein, we describe the novel maize gene extended auricle1 (eta1), which is essential for proper format...
