ZmCCT and the genetic basis of day-length adaptation underlying the postdomestication spread of maize.
Teosinte, the progenitor of maize, is restricted to tropical environments in Mexico and Central America. The pre-Columbian spread of maize from its center of origin in tropical Southern Mexico to the higher latitudes of the Americas required postdomestication selection for adaptation to longer day lengths. Flowering time of teosinte and tropical maize is delayed under long day lengths, whereas ...
متن کاملExcision of an active CACTA-like transposable element from DFR2 causes variegated flowers in soybean [Glycine max (L.) Merr.].
Active endogenous transposable elements, useful tools for gene isolation, have not been reported from any legume species. An active transposable element was suggested to reside in the W4 locus that governs flower color in soybean. Through biochemical and molecular analyses of several revertants of the w4-m allele, we have shown that the W4 locus encodes dihydroflavonol-4-reductase 2 (DFR2). w4-...
متن کاملThe hobo transposable element of Drosophila can be cross-mobilized in houseflies and excises like the Ac element of maize.
The hobo transposable element from Drosophila melanogaster was found to be capable of excision, resulting in donor sites unlike those reported for any other transposable element currently known in animals. These empty sites most closely resemble those left by the transposable elements Ac and Tam3 in Zea mays and Antirrhinum majus, respectively. Like Ac and Tam3, the hobo element was found to fu...
متن کاملSomatic excision of the Mu1 transposable element of maize.
The Mu transposons of the Robertsons's Mutator transposable element system in maize are unusual in many respects, when compared to the other known plant transposon systems. The excision of these elements occurs late in somatic tissues and very rarely in the germ line. Unlike the other plant transposons, there is no experimental evidence directly linking Mu element excision and integration. We h...
متن کاملA hyperactive transposase of the maize transposable element activator (Ac).
Activator/Dissociation (Ac/Ds) transposable elements from maize are widely used as insertional mutagenesis and gene isolation tools in plants and more recently also in medaka and zebrafish. They are particularly valuable for plant species that are transformation-recalcitrant and have long generation cycles or large genomes with low gene densities. Ac/Ds transposition frequencies vary widely, ho...
