Most orthology determination methods make use of sequence comparisons: the amino acid sequences of all proteins in two species are compared with each other, and the two sequences that are most similar are considered to be
orthologs.
The 2485 introns with
orthologs available in the two outgroup Palaeognathae species ranged from exhibiting no conflict to exhibiting considerable conflict (up to 950 genes or 38 %) for some branches of the TENT (Fig. 3A, blue numbers, and Fig. 5C).
«Missing» denotes the case in which
an ortholog is not present for any taxa or is present for only one taxon, and hence monophyly can not be determined.

Although CRISPR is incredibly useful for generating mutations by NHEJ and generating small mutations with HDR, when it comes to larger scale genome editing, such as replacement of a mouse gene with its human
ortholog (greater than 5 kb), it remains to be seen whether CRISPR is as robust as conventional gene targeting.

In rice, CYP724B1, encoded by the bsl1
ortholog D11, and CYP90B, encoded by OsDwf4, are partially redundant for C - 22 hydroxylation and the loss - of - function double mutants in OsDwf4 and D11 exhibited severe dwarfism and malformed, erect leaves (Sakamoto et al., 2006).
In addition, a number of key developmental regulators were expressed at higher levels in bsl1 - 1 mutants, including
orthologs of classical genes from maize that specify AM identity and determinacy (e.g., bd1 [Chuck et al., 2002] and ramosa1 [Vollbrecht et al., 2005]-RRB-, that pattern lateral organ development (e.g., narrow sheath1 [Scanlon et al., 1996] and yabby10 [Juarez et al., 2004]-RRB-, and those implicated in carpel repression in maize tassels (e.g., grassy tillers1 [Whipple et al., 2011], tasselseed 1 [Acosta et al., 2009], and tasselseed 2 [Irish and Nelson, 1993]-RRB-(Table 2).

orthologs of genes controlling pistil retention in maize were misregulated in bsl1 - 1 mutants.
To test this, we performed in situ hybridizations using a probe designed to the S. viridis
ortholog of the maize knotted1 (kn1) gene, a key marker of meristem maintenance (Kerstetter et al., 1997; Bolduc et al., 2012)(Supplemental Figure 10).
One of these SNPs resulted in a premature stop codon within Sevir.7 G140700 (+1860 from the transcriptional start site; Figure 3B), which encodes the syntenic
ortholog of Dwarf11 (D11) in rice, the cytochrome P450 724B involved in BR biosynthesis (Tanabe et al., 2005; Sakamoto et al., 2006).
Our RNA - seq analyses showed that SvBd1 (Sevir.2 G437800), encoding
the ortholog of a conserved AP2 - ERF TF, which specifies SM identity in maize and other grasses (Chuck et al., 2002), was expressed at substantially higher levels in the bsl1 - 1 mutant compared with the wild type, consistent with increased production of spikelets in place of bristles (Table 2).

The evidence of
ortholog genes expression which likely associated with Smad proteins, Wnt, TGF - β signaling pathways, and cartilage formation in S. pistillata supports previous reports suggesting that gene regulatory pathways of development and biomineralization processes across the metazoan evolution are considerably conserved (Jackson et al., 2007; Marin et al., 2008).
