Editing Chondrus crispus (section)

==Scientific interest==

''C. crispus'', compared to most other [[seaweed]]s, is well-investigated scientifically. It has been used as a model species to study [[photosynthesis]], carrageenan [[biosynthesis]], and stress responses. The [[nuclear genome]] was sequenced in 2013.<ref>{{cite journal | last1 = Collén | first1 = J |display-authors=et al | year = 2013 | title = Genome structure and metabolic features in the red seaweed ''Chondrus crispus'' shed light on evolution of the Archaeplastida | journal = Proceedings of the National Academy of Sciences | volume =  110| issue = 13| pages =  5247–5252| doi = 10.1073/pnas.1221259110 | pmid=23503846 | pmc=3612618| bibcode = 2013PNAS..110.5247C | doi-access = free }}</ref> The genome size is 105 [[Mega base pairs|Mbp]] and is coding for 9,606 genes. It is characterised by relatively few genes with very few [[intron]]s. The genes are clustered together, with normally short distances between genes and then large distances between groups of genes.
