  abstract: This research focuses on the isolation of the sorghum shattering gene (Sh1) and the photoperiodic flowering gene (Ma1). Shattering of the mature inflorescence is an important way for wild plants and weeds to disperse seeds but can cause economically significant grain losses in crop plants. Isolation of shattering genes can enhance understanding of seed dispersal processes and perhaps help in reducing gain losses. Most species in the grass family originate from tropical or subtropical areas with wild genotypes that are photoperiod-sensitive, in which flowering time is regulated by day length. The response of tropical genotypes to photoperiod has hindered the use of exotic neoplasm in temperate zones. Isolation of the photoperiodic flowering gene could help us understand how photoperiodic genes regulate flowering in response to daylength, and also help in breeding photoperiod-insensitive species adapted for temperate agriculture. A large insert Sorghum propinquum (K. Hitchcock) BAC library has been constructed to analyze the physical organization of the sorghum genome and to facilitate positional cloning of Shl, Mal, and other sorghum genes and QTLs associated with the early stages of grain crop domestication. This library consists of 38,016 BAC clones with an estimated average insert size of 126 kb and coverage of 6.6 genome-equivalents. The sorghum shattering gene, Shl has been genetically mapped to an interval of 0.8 cM, co-segregating with RZ474 and flanked by pSB097 and BCD1072b. Twelve BAC clones with an average size of 1 13 kb were the region of pSB097 and RZ474 (Sh1). The largest BAC in the contig, 39E2 1, has been used to screen a spanning Johnsongrass [Ssorghum halfpence (L.) Pers.inflorescence cDNA library, and six candidate cDNAs ] were identified. Four of the six may represent members of a gene cluster in this region. The sorghum photoperiodic gene, Mal, has been genetically mapped by using substitution mapping to an interval of 0.5 cM, flanked by pSB1113…
