Stripe rust (Puccinia striiformis f. sp. tritici; Pst) and powdery mildew (Blumeria graminis Bgt) are important diseases of wheat (Triticum aestivum) worldwide. Similar mechanisms gene transcripts assumed to be involved in the host defense response because both pathogens biotrophic fungi. The main objective our study was identify co-regulated mRNAs that show a change expression pattern after inoculation with Pst or Bgt, specific fungal stress response. transcriptome hexaploid line N9134...

The study of hydrodynamics liquid crystals leads to many fascinating mathematical problems, which has prompted various interesting works recently. This article reviews the static Oseen-Frank theory and surveys some recent progress on existence, regularity, uniqueness large time asymptotic hydrodynamic flow nematic crystals. We will also propose a few questions for future investigations.

In this paper, we establish a blow up criterion for the short time classical solution of nematic liquid crystal flow, simplified version Ericksen–Leslie system modeling hydrodynamic evolution crystals, in dimensions two and three. More precisely, 0 < T * + ∞ is maximal interval iff (i) n = 3, ; (ii) 2, .

Stripe rust (Puccinia striiformis f. sp. tritici; Pst) and powdery mildew (Blumeria graminis Bgt) are important diseases of wheat (Triticum aestivum) worldwide. Increasingly evidences suggest that long intergenic ncRNAs (lincRNAs) developmentally regulated play roles in development stress responses plants. However, identification lincRNAs is still limited comparing with functional gene expression. The transcriptome the hexaploid line N9134 inoculated Chinese Pst race CYR31 Bgt E09 at 1, 2, 3...

We consider a simplified version of Ericksen-Leslie equationmodeling the compressible hydrodynamic flow nematic liquidcrystals in dimension one. If initial data $(\rho_0, u_0,n_0)\inC^{1,\alpha}(I)\times C^{2,\alpha}(I)\times C^{2,\alpha}(I, S^2)$and $\rho_0\ge c_0>0$, then we obtain both existence and uniquenessof global classical solutions. For $0\le\rho_0\in H^1(I)$ $(u_0,n_0)\in H^1(I)\times H^2(I,S^2)$, anduniqueness strong

In this study, we research a nonautonomous, three-species, delayed reaction–diffusion predator–prey model (RDPPM). Firstly, derive sufficient conditions to guarantee the existence of strictly positive, spatially homogeneous periodic solution (SHPS) for delayed, nonautonomous RDPPM. These are obtained using comparison theorem differential equations and fixed point theorem. Secondly, present ensure global asymptotic stability SHPS established through application upper lower method (UALSM)...

We study solutions, with scaling-invariant bounds, to the steady simplified Ericksen-Leslie system in $\mathbb{R}^n\setminus \{0\}$. When $n=2$, we construct and classify a class of self-similar solutions. $n\ge 3$, establish rigidity asserting that if $(u,d)$ satisfies bound small constant, then $u\equiv 0$ $d=$ constant for $n\geq 4$ or $u$ is Landau solution $n=3$. Such smallness condition can be weaken when $n=4$ solutions are self-similar.
