Genome-Wide Analysis of YABBY Gene Family in Lettuce (Lactuca sativa) and Functional Characterization of LsaFILd

Identification, Molecular Characteristics, and Evolution of YABBY Gene Family in Melastoma dodecandrum

“…However, there were two proteins, MdYABBY5 and MdYABBY7 , which were significantly different from the others in instability index, showing that these two MdYABBY proteins might play a different role in alternate microenvironments. All MdYABBYs were located in the nucleus, and the result of the subcellular localization analysis was consistent with the website’s prediction, indicating that MdYABBYs might play transcriptional regulatory roles in the nucleus, in agreement with previous findings in Lactuca sativa [ 6 ] and Glycine max [ 14 ].…”

“…In comparison, MdYABBYs were divided into four clades, and no MdYABBY protein was found in clade INO, which might be lost in the interspecific differentiation process. This phenomenon is also found in L. sativa , which loses clade YABBY2 [ 6 ]. M. indica only has three clades, including CRC, YAB5, and YAB3 [ 22 ].…”

“…Gene structure is often conserved during evolution [ 4 ]. Previous studies have shown that the YABBY gene family contains two typical conserved protein domains, C2C2 zinc finger and YABBY [ 2 , 4 , 5 , 6 ]. The amino acid sequence alignment showed that MdYABBY genes also contained these two typical conserved protein domains ( Figure 2 ), indicating that the C2C2 zinc finger and YABBY domains were conserved in plant [ 2 , 4 , 5 , 6 ].…”

What’s more, the MdYABBYs in the same clade in the phylogenetic tree had the same motifs ( Figure 3 A), indicating that these genes probably had similar molecular functions.…”

“…YABBY is a family of TFs belonging to the zinc finger protein superfamily [ 2 ]. YABBY genes play crucial roles in the formation of lateral organs during plant growth and development [ 3 , 4 , 5 , 6 ]. The YABBY family contains two typical domains, the YABBY domain in the C-terminus and the C2C2 zinc finger domain in the N-terminus [ 2 , 7 ].…”
