We have examined the development of innervation to the indirect flight muscles of Drosophila. During metamorphosis, the larval intersegmental nerve of the mesothorax is remodelled to innervate the dorsal longitudinal muscles and two of the dorsoventral muscles. Another modified larval nerve innervates the remaining dorsoventral muscle. The dorsal longitudinal muscles develop using modified larval muscles as templates while dorsoventral muscles develop without the use of such templates. The development of innervation to the two groups of indirect flight muscles differs in spatial and temporal patterns, which may reflect the different ways in which these muscles develop. The identification of myoblasts associated with thoracic nerves during larval life and the association of migrating myoblasts with nerves during metamorphosis indicate the existence of nerve-muscle interactions during indirect flight muscle development. In addition, the developing pattern of axonal branching suggests a role for the target muscles in respecifying neuromuscular junctions during metamorphosis.

Twist is required in Drosophila embryogenesis for mesodermal specification and cell-fate choice. We have examined the role of Twist and Notch during adult indirect flight muscle development. Reduction in levels of Twist leads to abnormal myogenesis. Notch reduction causes a similar mutant phenotype and reduces Twist levels. Conversely, persistent expression, in myoblasts, of activated Notch causes continued twist expression and failure of differentiation as assayed by myosin expression. The gain-of-function phenotype of Notch is very similar to that seen upon persistent twist expression. These results point to a relationship between Notch function and twist regulation during indirect flight muscle development and show that decline in Twist levels is a requirement for the differentiation of these muscles, unlike the somatic muscles of the embryo.

Pointed End

Tropomodulin (Tmod) is an actin pointed-end capping protein that regulates actin dynamics at thin filament pointed ends in striated muscle. Although pointed-end capping by Tmod controls thin filament lengths in assembled myofibrils, its role in length specification during de novo myofibril assembly is not established. We used the Drosophila Tmod homologue, sanpodo (spdo), to investigate Tmod's function during muscle development in the indirect flight muscle. SPDO was associated with the pointed ends of elongating thin filaments throughout myofibril assembly. Transient overexpression of SPDO during myofibril assembly irreversibly arrested elongation of preexisting thin filaments. However, the lengths of thin filaments assembled after SPDO levels had declined were normal. Flies with a preponderance of abnormally short thin filaments were unable to fly. We conclude that: (a) thin filaments elongate from their pointed ends during myofibril assembly; (b) pointed ends are dynamically capped at endogenous levels of SPDO so as to allow elongation; (c) a transient increase in SPDO levels during myofibril assembly converts SPDO from a dynamic to a permanent cap; and (d) developmental regulation of pointed-end capping during myofibril assembly is crucial for specification of final thin filament lengths, myofibril structure, and muscle function.

Mutant Lines

An extensive ethylmethanesulfonate mutagenesis of Drosophila melanogaster was undertaken to isolate the stronger alleles of 3 indirect flight-muscle mutations. We isolated 17 strong mutant lines, with nearly complete penetrance and expressivity, using direct screening under polarized light, from more than 1700 mutagenized chromosomes. On complementation, we found 11 of these 17 mutant lines to be alleles of 3 indirect flight-muscle mutations (Ifm(2)RU1, 3 noncomplementing lines; ifm(2)RU2, 6 alleles; ifm(2)RU3, 2 alleles) of the previously isolated 8 complementation groups (Ifm(2)RU1to ifm(2)RU8). In addition, we found 6 new complementation groups with strong defects in adult-muscle morphology; we named these ifm(2)RS1 to ifm(2)RS6. All mutant lines were mapped by meiotic recombination, and 5 of the 6 new complementation lines were mapped using chromosome deficiencies. ifm(2)RS1 maps to a region that harbors ifm(2)RU4 (a mutation that was isolated previously); however, theses are not alleles because each complements the other mutation, and the mutant-muscle phenotype is very different. We used direct screening under polarized light to find recessive mutations; although this method was labor intensive, it can be used to identify recessive genes involved in myogenesis, unlike screens for flightlessness or wing-position defects. This screen identifies regions on the second chromosome that harbor probable genes that are likely expressed in the mesoderm and are thought to be involved in myogenesis. This screen has generated valuable resources that will help us to understand the role of many molecular players involved in myogenesis.
