+ORTHOSCOPE Analysis Reveals the Presence of the Cellulose Synthase Gene in All Tunicate Genomes but Not in Other Animal Genomes.

cellulose I was also found in _O. rufescens by_ [[Kimura and coll
(2001)|biblio/11732199]]. The CesA gene is trans-spliced in the ascidian _Ciona
intestinalis_ ([[Matthysse and coll., 2004|biblio/14722352]]).
+ - A GH6 (glycosyl hydrolase family 6) domain is found in the CesA genes,
+ as well as an independent genes, in Tunicates
+ ([[Inoue, Nakashima and Satoh, 2019|biblio/30974905]]).
- _O. dioica_ has multiple CDK1 and Cyclin B paraplogs, some of which are
implicated in oogenesis ([[Øvrebø and coll., 2015|biblio/25714331]],
[[Feng & Thompson, 2018|biblio/29969934]]).
- Components of the constitutive centromere-associated network (CCAN) of the
inner kinetochore cound not be found in the genome by ([[Feng and coll.,
2019|biblio/31306061]]).
+ - _Nodal_ is not found in _O. dioica_'s genome ([[Onuma and coll., 2020|biblio/32029598]]).

phase, while in endocycling cells, it increases directly after the end of
the S phase ([[Spada, Chioda and Thompson (2006)|biblio/15937898]]).

Transcriptome
-------------
- On the histone mRNAs, no purine-rich histone downstream element (HDE) was found
by [[Chioda, Eskeland and Thompson in 2002|biblio/12446815]].

the genome (doubling the genes would then double the amount of regulatory sequences).
- Regular calcium waves are pulsing during embyogenesis. Their propagation and
synchronicity is severly disrupted by the knockdown of the connexins CxA and CxB
- ([[Mikhaleva, Tolstenkov and Glover 2019|biblio/30905687]]).
+ ([[Mikhaleva, Tolstenkov and Glover 2019|biblio/30905687]]). The calcium waves
+ are required for Bmp.a expression in descendants of the R (Right) blastomere
+ ([[Onuma and coll., 2020|biblio/32029598]]).
- The tandem _propA_ and _propB_ genes control directly or indirectly _oik41a_
and proper development of the house-secreting epithelium ([[Mikhaleva et
al., 2018|biblio/30217597]]).
