in taxon negatively regulates nematode larval development negative regulation of post-embryonic development regulation of nematode larval development negative regulation of nematode larval development Any process that decreases the rate, frequency, or extent of nematode larval development, 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. 2010-03-11T01:04:39Z dph GO:0061064 biological regulation Bilateria
