Alternative names are given in parentheses.
Systematic names given to genes by MIPS (http://mips.gsf.de/proj/thal/) from AGI sequencing project.
BAC accession nos. are for genomic DNA sequences deposited in NCBI database (http://www.ncbi.nlm.nih.gov/).
Gene expression is based on northern analysis, cloned cDNA, or the presence of EST. The no. of ESTs in the MIPS database is indicated. An asterisk indicates that there is no EST in the database.
The no. of predicted amino acids.
The no. of Garlic (G) and SALK (S) T-DNA insertion lines available from TMRI/Syngenta (http://www.tmri.org) and Salk Institute Genomic Analysis laboratory (http://signal.salk.edu), respectively, is presented. The toc1 mutant has a point mutation (Strayer et al. 2000).
