This presents a substantial barrier to the development of new approaches to prevent or ameliorate the disease. In this review, we first summarize the neutrophil functions affected by the established periodontal pathogens listed above, denoting unknown areas that still merit a closer look. Then, we review the literature on neutrophil functions and the emerging periodontal pathogens, F. alocis and P. stomatis, comparing the effects of the emerging microbes to that of established pathogens, and speculate on the contribution of these putative pathogens to the progression of periodontal disease.New genes (or lineage-specific genes) can facilitate functional innovations. MALE STERILITY 5 (MS5) in Brassica napus is a fertility-related new gene, which has two wild-type alleles (BnMS5a and BnMS5c ) and two mutant alleles (BnMS5b and BnMS5d ) that could induce male sterility. Here, we studied the history and functional evolution of MS5 homologs in plants by phylogenetic analysis and molecular genetic experiments. We identified 727 MS5 homologs and found that they define a Brassicaceae-specific gene family that has expanded partly via multiple tandem gene duplications and also probably transpositions. The MS5 in B. napus is inherited from a basic diploid ancestor of B. rapa. Molecular genetic experiments indicate that BnMS5a and BnMS5c are functionally distinct in B. napus and that BnMS5d can inhibit BnMS5a in B. napus in a dosage-dependent manner. The BnMS5a protein can move in coordination with meiotic telomeres and interact with the nuclear envelope protein SUN1, with a possible crucial role in meiotic chromosome behavior. In summary, BnMS5 belongs to a Brassicaceae-specific new gene family, and has gained a novel function that is essential for male fertility in B. na
