Culm wall thickness, diameter, and strength are different traits that can govern the lodging resistance in rice. The genes SCM2 and FC1 have been isolated for culm thickness, strength, and flexibility, but their functional nucleotide variations were still unknown. We used a 13\u00d7 deep sequence of 795 diverse genotypes to present the functional variation and SNP diversity in SCM2 and FC1. The major functional variant for the SCM2 gene was at position 27480181 and for the FC1 gene at position 31072992. Haplotype analysis of both genes provided their various allelic differences among haplotypes. SCM2 alleles further presented the evolution of Oryza sativa L. subsp. indica and subsp. japonica genomes from common parent in different geographical zones, while the haplotypes of FC1 suggested their evolution from different strains of the common parent Oryza rufipogon. SCM2 showed purifying selection and functional associations with rare alleles, while FC1 displayed balanced selection favored by multiple heterozygous alleles. Genotypes with an allelic combination of SCM2-3 and FC1-2 in japonica background exhibited striking resistance against lodging, which can be used in further breeding programs. <\/jats:p>","DOI":"10.1139\/gen-2016-0019","type":"journal-article","created":{"date-parts":[[2016,5,12]],"date-time":"2016-05-12T21:37:42Z","timestamp":1463089062000},"page":"473-483","update-policy":"https:\/\/doi.org\/10.1139\/csp-crossmark-policy","source":"Crossref","is-referenced-by-count":13,"title":["Nucleotide diversity, natural variation, and evolution of <i>Flexible culm-1<\/i> and <i>Strong culm-2<\/i> lodging resistance genes in rice"],"prefix":"10.1139","volume":"59","author":[{"given":"Muhammad Abdul Rehman","family":"Rashid","sequence":"first","affiliation":[{"name":"Key Laboratory of Crop Heterosis and Utilization, Ministry of Education\/Beijing Key Laboratory of Crop Genetic Improvement, China Agricultural University, Beijing 100193, China."},{"name":"Key Laboratory of Crop Heterosis and Utilization, Ministry of Education\/Beijing Key Laboratory of Crop Genetic Improvement, China Agricultural University, Beijing 100193, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Crop Heterosis and Utilization, Ministry of Education\/Beijing Key Laboratory of Crop Genetic Improvement, China Agricultural University, Beijing 100193, China."},{"name":"Key Laboratory of Crop Heterosis and Utilization, Ministry of Education\/Beijing Key Laboratory of Crop Genetic Improvement, China Agricultural University, Beijing 100193, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongliang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Crop Heterosis and Utilization, Ministry of Education\/Beijing Key Laboratory of Crop Genetic Improvement, China Agricultural University, Beijing 100193, China."},{"name":"Key Laboratory of Crop Heterosis and Utilization, Ministry of Education\/Beijing Key Laboratory of Crop Genetic Improvement, China Agricultural University, Beijing 100193, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinjie","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Crop Heterosis and Utilization, Ministry of Education\/Beijing Key Laboratory of Crop Genetic Improvement, China Agricultural University, Beijing 100193, China."},{"name":"Key Laboratory of Crop Heterosis and Utilization, Ministry of Education\/Beijing Key Laboratory of Crop Genetic Improvement, China Agricultural University, Beijing 100193, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zichao","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Crop Heterosis and Utilization, Ministry of Education\/Beijing Key Laboratory of Crop Genetic Improvement, China Agricultural University, Beijing 100193, China."},{"name":"Key Laboratory of Crop Heterosis and Utilization, Ministry of Education\/Beijing Key Laboratory of Crop Genetic Improvement, China Agricultural University, Beijing 100193, China."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"155","reference":[{"key":"refg1\/ref1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0120186"},{"key":"refg2\/ref2","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/btm308"},{"key":"refg3\/ref3","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pgen.0030163"},{"key":"refg4\/ref4","doi-asserted-by":"publisher","DOI":"10.1093\/molbev\/msg004"},{"key":"refg5\/ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2006.12.006"},{"key":"refg6\/ref6","doi-asserted-by":"publisher","DOI":"10.1534\/genetics.104.035642"},{"key":"refg7\/ref7","doi-asserted-by":"publisher","DOI":"10.2134\/agronj1954.00021962004600090006x"},{"key":"refg8\/ref8","doi-asserted-by":"publisher","DOI":"10.1007\/s00122-008-0777-4"},{"key":"refg9\/ref9","first-page":"157","volume":"29","author":"Hojyo Y.","year":"1974","journal-title":"Agric.
