Context examples:
The Cavendish — which accounts for nearly half of all banana varieties grown in the world and most imports into Europe and the US — can be protected by splicing in genes from banana varieties resistant to the deadly Tropical Race 4 (TR4) strain of the Fusarium oxysporum fungus as well as a gene from a nematode worm.

Scientists undertook this large project to better understand the molecular and cellular mechanisms that underpin the peanut plant’s growth and development, as well as the expression of desirable traits, like high seed yield, improved oil quality and resistance to costly diseases and pests such as root knot nematodes.

Any chemical substance, biological agent or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest, including insects, plant pathogens, weeds, mollusks, birds, mammals, fish, nematodes (roundworms) and microbes that compete with humans for food, destroy property, spread or are a vector for disease or are a nuisance.

Researchers in Barabási's lab studied the nematode brain, which has been mapped neuron by neuron, synapse by synapse.
(Fundamental Rules for How The Brain Controls Movement, The Titi Tudorancea Bulletin)
The brain of a nematode worm, for example, has about 300 neurons and 2,200 synapses.

And in research, they describe for the first time their ability to predict, test, and confirm with unprecedented detail how a nematode's brain controls the way it moves.
(Fundamental Rules for How The Brain Controls Movement, The Titi Tudorancea Bulletin)
Using the nematode as one test system, scientists at CCNR have spent the past several years understanding how a network controls itself — for instance, which individual neurons in the worm's brain are in charge of a backward wiggle.
