For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
SpletBark is the outermost layers of stems and roots of woody plants.Plants with bark include trees, woody vines, and shrubs.Bark refers to all the tissues outside the vascular cambium and is a nontechnical term.
