Trypan blue staining and sterile culture revealed that the mutant spontaneously developed lesions on the leaves in a develop mentally regulated and light-dependent manner. Genetic analysis indicated that the lesion mimic trait was controlled by a single resessive locus. Using public molecular markers and an F2 population derived from lmi and 93-11, we mapped the lmi locus to the short arm of chromosome 8, nearby the centromere, between two SSR markers RM547 and RM331. The genetic distance was 1.2 and 3.2 Cm, respectively. Then according to the public rice genomic sequence between the two SSR markers, lmi was further finely tagged by three CAPS markers: C4135-8, C4135-9 and C4135-10. And lmi locus was a co-segregated with marker C4135-10, providing a starting point for imi gene cloning.展开更多

The length of diffuser was varied from 4 to 20times the width of diffuser. The calculations were performed with the standard K-ε model and HybridFinite Analytic Method (HFAM) with staggered grid. The phenomenon and development of vortex pairsare simulated successfully and the influence of diffuser length and buoyant on turbulent buoyantjets are analyzed.展开更多
