Database searches were as described in the legend to Figure 1, and Figure labeling is also as described in Figure 1. The asterisk in the LjPLP-I denotes an amber stop in the Sec14-domain coding sequence (55), and the Lotus japonicus genome assembly build 3.0 tool (http://www.kazusa.or.jp/lotus/blast.html) predicts two annotated genes (Lj4g3v0988870.1 and Lj4g3v0988870.2, rather than a single Sec14-nodulin gene as shown here. The .1 and .2 suffixes indicate alternative splicing from the same pre-mRNA. The predicted Lj4g3v0988870.1 translation product is a 384 polypeptide containing the N-terminal 159 residues of the Sec14 domain, while the Lj4g3v0988870.2 is predicted to encode a 314 amino acid polypeptide consisting of a 79 residue C-terminus from the Sec14-domain joined to the nodulin-domain. As translational read-through of translation stop codons is known, we list the full-length LjPLP-I polypeptide (550 amino acids) as such read-through could potentially generate such a translation product at some low frequency. Thus, the Sec14-nodulin protein family of Lotus consists of at least three, and perhaps four, proteins.
