Insect dendritic arborization (da) neurons provide an opportunity to examine how diverse dendrite morphologies and dendritic territories are established during development. We have examined the morphologies of Drosophila da neurons by using the MARCM (mosaic analysis with a repressible cell marker) system. We show that each of the 15 neurons per abdominal hemisegment spread dendrites to characteristic regions of the epidermis. We place these neurons into four distinct morphological classes… 
Projections of Drosophila multidendritic neurons in the central nervous system: links with peripheral dendrite morphology
TLDR
A class-specific medial-lateral layering of axons in the central nervous system formed during embryonic development is identified, which could allow different classes of da neurons to develop differential connectivity to second-order neurons.
Control of multidendritic neuron differentiation in Drosophila: the role of Collier.
TLDR
Findings indicate that col is required in at least two distinct programs that control the morphological and sensory specificity of Drosophila md neurons, even though these originate from two types of sensory precursor cells.
Immunohistological labeling of microtubules in sensory neuron dendrites, tracheae, and muscles in the Drosophila larva body wall.
TLDR
This protocol illustrates the dissection and immunostaining of first instar larva, a stage when active sensory neuron dendrite outgrowth and branching organization is occurring, and achieves robust labeling of microtubule organization in muscles, trachea, and other body wall tissues.
Morphological analysis of Drosophila larval peripheral sensory neuron dendrites and axons using genetic mosaics.

TLDR
A practical guide to generate and analyze genetic mosaics by marking DA neurons via MARCM (Mosaic Analysis with a Repressible Cell Marker) and Flp-out techniques (summarized in Fig. 1).
The RhoGEF Trio Functions in Sculpting Class Specific Dendrite Morphogenesis in Drosophila Sensory Neurons
TLDR
These analyses implicate Trio as an important regulator of class specific da neuron dendrite morphogenesis via interactions with Rac1 and Rho1 and indicate that Trio is required as downstream effector in Cut-mediated regulation of dendritic branching and filopodia formation.
Golden goal controls dendrite elongation and branching of multidendritic arborization neurons in Drosophila
TLDR
It is shown that Gogo is required to restrain the growth of ddaC dendrites toward the midline in the embryo, and results suggest Gogo plays important roles in maintaining homeostasis of dendritic branching.
Drosophila Dendritic Arborisation Neurons: Fantastic Actin Dynamics and Where to Find Them
TLDR
The differences in the growth programs leading to morphologically different dendritic trees are presented, with a focus on the key role of actin modulatory proteins.
The bHLH-PAS protein Spineless is necessary for the diversification of dendrite morphology of Drosophila dendritic arborization neurons.
TLDR
Spineless, the Drosophila homolog of the mammalian aryl hydrocarbon (dioxin) receptor (Ahr), regulates dendrite diversity in the dendritic arborization (da) sensory neurons, suggesting that one evolutionarily conserved role for Ahr in neuronal development concerns the diversification of dendrites morphology.
Multidendritic sensory neurons in the adult Drosophila abdomen: origins, dendritic morphology, and segment- and age-dependent programmed cell death
TLDR
This study identifies multidendritic neurons in the adult Drosophila abdomen, visualized the dendritic arbors of the individual neurons, and traced the origins of those cells back to the larval stage, providing the basis on which to investigate the genetic programs controlling dendrite remodeling and programmed cell death of adult neuron, and the life-long maintenance of dendritis arbors.
Identification of genes influencing dendrite morphogenesis in developing peripheral sensory and central motor neurons
TLDR
Comparisons between the screens suggest that the dendrites of peripheral da and central RP2 neurons are shaped by regulatory programs that only partially overlap, and commonalities and distinctions are identified in the molecular and organizational framework that underlies dendrite development of peripheral and central neurons.

TLDR
The stereotyped segmental and dorso-ventral organization of the peripheral nervous system of Drosophila embryos allows the identification of all the neurons in the body wall and provides a favorable assay system for the genetic analysis of neurodevelopment.
Tiling of the body wall by multidendritic sensory neurons in Manduca sexta
TLDR
The body wall is independently tiled by the beta and gamma da neurons and partially innervated by the alpha neurons, which likely allow insects to discriminate the quality and location of several types of stimuli acting on the cuticle.

TLDR
A classification of sensory neurons based on their axon morphology correlates closely with the identity of the proneural gene responsible for their generation, suggesting that proneural genes play a central role in determining neuronal identity in the PNS of the embryo.
Origin and specification of type II sensory neurons in Drosophila.
TLDR
Using the flp/FRT recombinase system from yeast, it is determined that a subset of md neurons derives from es organ lineages, another subset derives from ch organ lineage and a third subset is unrelated to sensory organs.
Lineage, cell polarity and inscuteable function in the peripheral nervous system of the Drosophila embryo.
TLDR
This study establishes for the first time the function of Inscuteable in the PNS, and provides the basis for studying the mechanisms controlling planar and apical-basal cell polarities in the embryonic sensory organ lineages.
Genes regulating dendritic outgrowth, branching, and routing in Drosophila.
TLDR
From a genetic screen, several genes that control different aspects of dendrite development including dendritic outgrowth, branching, and routing are identified including kakapo, a large cytoskeletal protein related to plectin and dystrophin; flamingo, a seven-transmembrane protein containing cadherin-like repeats; enabled, a substrate of the tyrosine kinase Abl; and nine potentially novel loci.
Central projections of Drosophila sensory neurons in the transition from embryo to larva
TLDR
The central projections of sensory neurons in the first instar Drosophila larva are described, relating them to the projection of the same sensory afferents in the embryo and to sensoryafferents of similar type in other insects.

TLDR
The embryonic development of the epidermal receptive fields of the PV and PD mechanosensory neurons present in each segmental ganglion of the ventral nerve cord of the glossiphoniid leech Haementeria ghilianii is charted to suggest that developing branches of a neuron are excluded from territory occupied by other branches of the same cell, in contrast to branches belonging to different neurons which can occupy the same territory.

The anatomy of the sensory axons of two species of fly are examined and it is demonstrated that the location of the axonal projections in the CNS can be correlated with the modality they encode.
