In this paper, we developed a stability analysis for discrete-time uncertain time-delay systems governed by an infinite-state Markov chain(DUTSs-IMC). Some sufficient conditions for the considered systems to be exponential stability in mean square with conditioning(ESMS-C) are derived via linear matrix inequalities(LMIs), which can be examined conveniently. Under novel sufficient conditions, the equivalence among asymptotical stability in mean square(ASMS), stochastic stability(SS), exponential stability in mean square(ESMS), and ESMS-C has been established. Besides, numerical simulations are employed in result validation.

Optimizing the profile and quantity of fatty acids in rapeseed(Brassica napus L.) is critical for maximizing the value of edible oil and biodiesel. However, selection of these complex seed quality traits is difficult before haplotypes controlling their contents are identified. To efficiently identify genetic loci influencing these traits and underlying candidate genes and networks, we performed a genome-wide association study(GWAS) of eight seed quality traits(oil and protein content, palmitic, stearic, oleic, linoleic, eicosenoic and erucic acids content). The GWAS population comprised 370 diverse accessions, which were phenotyped in five environments and genotyped using 60K SNP arrays. The results indicated that oil and protein contents generally showed negative correlations, while fatty acid contents showed positive or negative correlations,with palmitic and erucic acid contents directly affecting oil content. Seven SNPs on five chromosomes were associated with both seed oil and protein content, and five genes orthologous to genes in Arabidopsis thaliana were predicted as candidates. From resequencing data, besides known haplotypes in Bna ***1.a and Bna ***1.a, three accessions harboring a new haplotype conferring moderate erucic acid content were identified. Interestingly, in a haplotype block, one haplotype was associated with high palmitic acid content and low oil content, while the others showed the reverse effects. This finding was consistent with a negative correlation between palmitic acid and oil contents, suggesting historical selection for high oil content. The identification by this study of genetic variation and complex correlations of eight seed quality traits may be beneficial for crop selection strategies.

Oilseed rape(Brassica napus) is an allotetraploid with two subgenomes descended from a common ancestor. Accordingly, its genome contains syntenic regions with many duplicate genes, some of which may have retained their original functions, whereas others may have diverged. Here, we mapped quantitative trait loci(QTL) for stem rot resistance(SRR), a disease caused by the fungus Sclerotinia sclerotiorum, and flowering time(FT) in a recombinant inbred line population. The population was genotyped using *** 60 K single nucleotide polymorphism arrays and phenotyped in six(FT) and nine(SSR) experimental conditions or environments. In total, we detected 30 SRR QTL and 22 FT QTL and show that some of the major QTL associated with these two traits were co-localized,suggesting a genetic linkage between them. Two SRR QTL on chromosome A2 and two on chromosome C2 were shown to be syntenic, suggesting the functional conservation of these regions. We used the syntenic properties of the genomic regions to exclude genes for selection candidates responsible for QTL-associated traits. For example, 152 of the 185 genes could be excluded from a syntenic A2–C2 region. These findings will help to elucidate polyploid genomics in future studies, in addition to providing useful information for B. napus breeding programs.

In this paper,we consider the finite horizon H2/H∞ control problem for linear stochastic differential equations（SDEs） with infinite Markovian jumps.A necessary and sufficient condition is proposed for the existence of the mixed H2/H∞control by means of the solvability of the coupled difference Riccati equations（CDREs）.Moreover,the state feedback H2/H∞controller is constructed through the solution of CDREs.
