Nuclear-encoded chloroplast proteins usually have an N-terminal targeting sequence and are translated on cytoplasmic 80 S ribosomes as precursors; import into the organelle is accompanied by removal of the "transit" peptide to generate the mature protein (reviewed in [ 1]).
Another goal advancing a more sustainable urban future is the calibration of the density and land use mix to generate transit ridership, vibrant retail and amenity services in neighbourhood nodes, as well as a balanced mix of employment uses that compliments a variety of residential options.
These cells divide to generate transit-amplifying type C cells, which generate new neurons that migrate along a well-defined pathway, the rostral migratory stream (RMS), to the olfactory bulbs (OBs) where they differentiate into interneurons [ 1].
The Toronto Transit Commission relies on its riders to generate its transit system.
They divide slowly to generate rapidly dividing transit amplifying cells, which in turn give rise to neuroblasts.
Upon loss of contact to their niche, stem cells differentiate into transit-amplifying cells that migrate upward to generate absorptive enterocyte and the secretory goblet, enteroendocrine and tuft cells.
Among other things, he proposes local waste-to-energy and anaerobic digesters (automated compost piles), urban gardens, congestion pricing for cars and trucks to generate subsidies for mass transit, and care for a water supply system that he pronounces "a good news story that will only stay good if we pay attention and protect it from harm".
The paper also shows how to use these results to generate master plans of transit systems for real cities.
Remarkably, translation of NaRpoTp mRNA has to be initiated at a CUG codon to generate a functional plastid transit peptide.
Many transit agencies invest substantial resources in surveying their passengers to generate data used for planning, marketing, and equity analyses.
