  1. Dec 25, 2013 · Replacement of the wingless (wg) gene in Drosophila with one that expresses a membrane-tethered form of Wg results in viable flies with normally patterned appendages of nearly the right size ...

  2. Wingless flies. True flies are insects of the order Diptera. The name is derived from the Greek di- = two, and ptera = wings. Most insects of this order have two wings (not counting the halteres, club-like limbs which are homologous to the second pair of wings found on insects of other orders).

  3. Aug 22, 2022 · Drosophila Wingless (Wg) is the founding member of the Wnt family. It was not until 1973 that wingless flies were found in a stock by serendipity, and this mutation, named wingless1 (wg1),...

  4. Apr 1, 2018 · Wingless, the fly homolog of the mammalian Wnt oncoproteins, plays a central role in pattern generation during development. Much of what we know about the pathway was learned from genetic and molecular experiments in Drosophila melanogaster, and the core pathway works the same way in vertebrates.

  5. Depending on how strict you want to be, you might say that flying squirrels, flying frogs and flying lizards all count. But these are really only gliding or parachuting, and the various flaps of skin stretched between their legs, toes or ribs are also suspiciously similar to wings.

  6. Aug 22, 2022 · The first mutation of the wingless gene was found by accident in Drosophila in the 1970s, following the observation of flies that did not possess wings, hence its name. Fifteen years after...

  8. The cuticle pattern secreted by the fruit fly embryonic epidermal cells is exquisitely sensitive to Wg signaling levels. The wg gene is expressed in just a single row of epidermal cells in each segment (Figs. 1 A and 2 B; Baker, 1988 ), but Wg activity influences cell fates across the segment.
