a, Nomenclatures used in Li et al. (1998, 1999, 2001), Bischoff et al. (2000), and Molendijk et al. (2000). b, Nomenclature used in Winge et al. (1997, 2000). c, Nomenclature used in Kost et al. (1999) and Lemichez et al. (2001).
AGI gene nomenclature.
Genebank protein accession no. (GI:) for a translation of the corresponding gene.
PM, Plasma membrane; ND, not determined. Numbers in superscript refer to articles where expression and localization data can be found: 1, Li et al. (1998); 2, Winge et al. (1997); 3, Zheng et al. (2002); 4, Li et al. (1999); 5, Jones et al. (2002) and Fu et al. (2002); 6, Bischoff et al. (2000); 7, Z.L. Zheng and Z. Yang, unpublished data.
AtROP3 is the same as ATGP2 (GI: 4097563).
AtROP4 is the same as ATGP3 (GI: 4097565). The accession number GI: 2654009 (“RHO-like GTP binding protein”) refers also to AtROP4.
GI: 2654011 corresponds also to AtROP5, but the sequence is incorrect; the last 100 amino acid residues are missing.
AtROP6 is the same as the clone At43 published by Xia et al. (1996) and defined in the database as “Arabidopsis Rho1Ps homolog” (GI: 1732519). AtROP6 is also found in the database under the accession number GI: 2645643.
The accession no. GI: 4678324 refers also to AtROP10/Arac8, but the splicing suggested in the database is inaccurate; the last exon is missing.
The first intron of AtROP11/Arac10 gene contains a cryptic exon of unknown function (GI: 7211195).
