Because of its popularity as an ornamental plant in East Asia, mei (Prunus mume Sieb. et Zucc.) has received increasing attention in genetic and genomic research with the recent shotgun sequencing of its genome. Here, we performed the genome-wide characterization of simple sequence repeats (SSRs) in the mei genome and detected a total of 188,149 SSRs occurring at a frequency of 794 SSR/Mb. Mono...

The correlations between GBS, dengue, Multivariate El Nino Southern Oscillation Index (MEI) and local meteorological data were explored by the Spearman Rank correlations and cross-correlations between these time series. Poisson regression models were fitted to identify nonlinear associations between MEI and dengue. Cross wavelet analysis was applied to infer potential non-stationary oscillating...

Mutations in the Drosophila mei-S332 gene cause premature separation of the sister chromatids in late anaphase of meiosis I. Therefore, the mei-S332 protein was postulated to hold the centromere regions of sister chromatids together until anaphase II. The mei-S332 gene encodes a novel 44 kDa protein. Mutations in mei-S332 that differentially affect function in males or females map to distinct d...

The recombination and repair defective mutant, mei-41, exhibits three rather striking effects on the genetic properties and chromosomal stability of rDNA in Drosophila. First, mei-41 inhibits rDNA magnification. However, mei-9, another recombination and repair defective mutation has no similar effect. This indicates that magnification requires some, but not all, of the gene products necessary f...

Medicare payments for physician services under Part B were historically restrained by capping prevailing charges using the Medicare Economic Index (MEI). The MEI, an input price index for physician services that incorporates an adjustment for economywide labor productivity, has not undergone a major revision since 1975. The MEI is an important determinant of the annual volume performance standa...

abstract The key to the method of measured equation of invariance (MEI) is the postulate: \the MEI is invariant to the excitation". In this paper, we proved that the MEI is independent of the excitation with the error bounded by O(h 2), where h is the discretization step. We also proved that the consistent condition jjLL?M=h 2 jj = ", where L is the partial diierential operator, and M the equiv...

Genetic evidence suggests that the mei-1 locus of Caenorhabditis elegans encodes a maternal product required for female meiosis. However, a dominant gain-of-function allele, mei-1(ct46), can support normal meiosis but causes defects in subsequent mitotic spindles. Previously identified intragenic suppressors of ct46 lack functional mei-1 activity; null alleles suppress only in cis but other all...

In Caenorhabditis elegans, the MEI-1-katanin microtubule-severing complex is required for meiosis, but must be down-regulated during the transition to embryogenesis to prevent defects in mitosis. A cullin-dependent degradation pathway for MEI-1 protein has been well documented. In this paper, we report that translational repression may also play a role in MEI-1 down-regulation. Reduction of spn...

TRIM-NHL proteins are a family of translational regulators that control cell growth, proliferation, and differentiation during development. Drosophila Brat and Mei-P26 TRIM-NHL proteins serve as tumor suppressors in stem cell lineages and have been proposed to exert this action, in part, via the repression of the protooncogene dMyc. Here we analyze the role of Brat, Mei-P26, and dMyc in regulat...

Simple meiotic gene conversion tracts produced in wild-type females were compared with those from two meiotic mutants, mei-9 and mei-218. The positions and lengths of conversion tracts were determined by denaturing gradient gels and DNA sequencing. Conversion tracts in wild type averaged 885 base pairs in length, were continuous, and displayed no obvious hot spots of initiation. Some unusual co...
