The process whose specific outcome is the progression of the nematode larva over time, from its formation to the mature structure. Nematode larval development begins with the newly hatched first-stage larva (L1) and ends with the end of the last larval stage (for example the fourth larval stage (L4) in C. elegans). Each stage of nematode larval development is characterized by proliferation of specific cell lineages and an increase in body size without alteration of the basic body plan. Nematode larval stages are separated by molts in which each stage-specific exoskeleton, or cuticle, is shed and replaced anew.

A series of molecular signals initiated by the binding of an extracellular ligand to a transforming growth factor beta receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

Any process that modulates the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

Any process that modulates the frequency, rate or extent of cell morphogenesis. Cell morphogenesis is the developmental process in which the shape of a cell is generated and organized.

A series of molecular signals initiated by the binding of a member of the BMP (bone morphogenetic protein) family to a receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

Any process that activates or increases the frequency, rate or extent of TGF-beta receptor signaling pathway activity.

Any process that activates or increases the frequency, rate or extent of DNA endoreduplication.

Any process that activates or increases the frequency, rate or extent of growth of an organism to reach its usual body size.

Any process that activates or increases the frequency, rate or extent of growth of an organism to reach its usual body size.

Any process that modulates the frequency, rate or extent of mesoderm cell fate specification.

Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.

The process in which the anatomical structure of the adult male tail tip is generated and organized. In some species of rhabitid nematodes, the male tail tip undergoes a morphological change such that the most posterior hypodermal cells in the tail (hyp8-11 in C. elegans) fuse and retract anteriorly, changing the shape of the tail from a pointed, tapered cone, or spike, to a rounded, blunt dome.

Any process that increases cell size.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that activates or increases the frequency, rate or extent of growth of an organ of an organism.

Reactions triggered in response to the presence of a Gram-negative bacterium that act to protect the cell or organism.

Reactions triggered in response to the presence of a Gram-positive bacterium that act to protect the cell or organism.

Reactions triggered in response to the presence of a fungus that act to protect the cell or organism.

A series of molecular signals initiated by the binding of an extracellular ligand to a transforming growth factor beta receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription, that modulates the frequency, rate or extent of growth of the body of an organism so that it reaches its usual body size.

A series of molecular signals initiated by the binding of an extracellular ligand to a transforming growth factor beta receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription, that modulates the frequency, rate or extent of growth of the body of an organism so that it reaches its usual body size.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
