Oryza rufipogon and O. longistaminata are important wild relatives of cultivated rice, harboring a promising source of novel genes for rice breeding programs. Here, we present de novo assembled draft genomes and annotation of O. rufipogon and O. longistaminata. Our analysis reveals a considerable number of lineage-specific gene families associated with the self-incompatibility (SI) and formation of reproductive separation. We show how lineage-specific expansion or contraction of gene families with functional enrichment of the recognition of pollen, thus enlightening their reproductive diversification. We documented a large number of lineage-specific gene families enriched in salt stress, antifungal response, and disease resistance. Our comparative analysis further shows a genome-wide expansion of genes encoding NBS-LRR proteins in these two outcrossing wild species in contrast to six other selfing rice species. Conserved noncoding sequences (CNSs) in the two wild rice genomes rapidly evolve relative to selfing rice species, resulting in the reduction of genomic variation owing to shifts of mating systems. We find that numerous genes related to these rapidly evolving CNSs are enriched in reproductive structure development, flower development, and postembryonic development, which may associate with SI in O. rufipogon and O. longistaminata.

Cystic fibrosis (CF) is a life-threatening and common genetic disorder. Cystic fibrosis newborn screening (CF NBS) has been implemented in many countries over the last 30 years, becoming a widely accepted public health strategy in economically developed countries. False-negative (FN) cases can occur after CF NBS, with the number depending on the method. We evaluated the delayed diagnosis of CF, identifying the patients who had false-negative CF NBS results over 26 years (1992-2018) in Tuscany, Italy. The introduction of DNA analysis to the newborn screening protocol improved the sensitivity of the test and reduced the FNs. Our experience showed that, overall, at least 8.7% of cases of CF received FNs (18 cases) and were diagnosed later, with an average age of 6.6 years (range: 4 months to 22 years). Respiratory symptoms and salt-loss syndrome (metabolic hypochloremic alkalosis) are suggestive symptoms of CF and were commons events in FN patients. In Tuscany, a region with a high CFTR allelic heterogeneity, the salt-loss syndrome was a common event in FNs. Therefore, we provided evidence to support the claim that the FN patients had CFTR mutations rarer compared with the true-positive cases. We underline the importance of vigilance toward clinical manifestations suggestive of CF on the part of the primary care providers and hospital physicians in a region with an efficient newborn screening program.
