Our understanding of the genes and networks that regulate grass inflorescence architecture has dramatically expanded due to significant advances in resources and tools. Beitr. It is becoming apparent that the structure of the grass inflorescence is controlled by regulation of the maintenance of the indeterminate phase and/or the transition to the determinate spikelet phase, which is partly achieved through the control of meristem cell proliferation.

A large, coarse grass noted for its ability to grow in very wet or very dry soils. Institute of Applied Agriculture Recommended for you. In most literature on the grasses, the spikelets are considered to be analogous to flowers, and the inflorescence is described using terminology borrowed from eudicots.

A gene controlling the number of primary rachis branches also controls the vascular bundle formation and hence is responsible to increase the harvest index and grain yield of rice. 2009. 1966. 2011. In some grasses the inflorescence will be one-sided. 1934. Plant J. Heterochronic development of the floret meristem determines grain number per spikelet in diploid, tetraploid and hexaploid wheats. Grasses, however, generally exhibit a determi- nate growth pattern of the overall flowering shoot, with the most mature spikelets toward the apex and least mature toward the base (asipetal). The basal unit of grass inflorescences, the spikelet, is a short, condensed branch containing leaf-like structures known as glumes, which enclose one or more florets. 9: e1003604.
