Distinct Genetic Architectures for Male and Female Inflorescence Traits of Maize Patrick J. , 1997 ). An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (peduncle) and by the timing of its flowering (determinate and indeterminate). Auxin signaling modules regulate maize inflorescence architecture Mary Gallia,1, Qiujie Liua,1, Britney L. Mossb, ... Grasses such as maize and rice contain inflorescences with mul-tiple types of specialized reproductive AMs. Description Maize (Zea mays L.) is one of the most important commercial crops in the world as well as an important model organism for basic research in plant biology. Here we show that one of these genes, RAMOSA3 (RA3), encodes a trehalose-6-phosphate phosphatase expressed in … Finally, genome-wide association studies for inflorescence architecture traits based only on functional regions delineated by MNase hypersensitivity revealed new SNP-trait associations in known regulators of inflorescence development as well as new candidates. Peer-reviewed and accepted for publication but not copyedited or typeset; preprint is … Brown 1,2 *, Narasimham Upadyayula 2 , Gregory S. Mahone 2 , Feng Tian 1 , Peter J. Bradbury 3 , The shoot architecture of maize is primarily determined by apical and axillary meristems, specialized groups of stem cells that are responsible for producing branches, lateral organs, and stems. The tassel forms directly from the shoot apical meristem after production of a defined number of leaves, whereas ears form at the tip of compact axillary branches. 1) The development of the maize plant, from germination to the maturation of the seed, is divided intothe vegetative, transitional, reproductive, and seedstages. € Preprint Accepted € likely to differ from the final, published version. In addition, maize has a rich genetic history and several mutations affecting discrete stages of inflorescence development have been described ( Neuffer et al. Variations in inflorescence branching patterns arise from position and developmental fate of differentiating stem cell populations called meristems. The Inflorescences of Maize.
1) The development of the maize plant, from germination to the maturation of the seed, is divided into the vegetative, transitional, reproductive, and seed stages. Use the dropdown menu to select a previously saved gene list and click on Find GO terms. male/female differentiation of spikelets and florets). Introduction. The ear and tassel differentiate and developin the reproductive stage. A major goal of my research thesis was to understand the role of different genetic, hormonal and environmental factors in regulating maize shoot growth to shed light on the molecular mechanisms underlying maize architecture.
These analyses provide a comprehensive look into the cis -regulatory landscape during inflorescence differentiation in a major cereal crop, which … The teosinte ear is composed of 5 to 10 (or more) distichously (in two ranks) arranged cupulate fruitcases. Maize ( Zea mays ) has a highly branched inflorescence due to the production of different types of axillary meristems.
Inflorescence, in a flowering plant, a cluster of flowers on a branch or a system of branches. Bonnett OT. 1) The development of the maize plant, from germination to the maturation of the seed, is divided intothe vegetative, transitional, reproductive, and seedstages. Maize (Zea mays L.) is one of the most important cereal crops in the world, and a main source of food, feed, and fuel.Improvement of grain yield is a primary task in most maize breeding programs. Inflorescence Architecture: The most dramatic differences between maize and teosinte involve the architecture of their female inflorescences (Figs. This inflorescence is found in Euphorbiaceae family like Euphorbia, Poinsettia, Pedilanthus. Regulatory modules controlling maize inflorescence architecture € P
