In this paper, we study the uniform attractor of the 2D non-autonomous tropical climate model in an arbitrary unbounded domain on which the Poincar\'e inequality holds. We prove that the uniform attractor is compact not only in the $L^2$-spaces but also in the $H^1$-spaces. Our proof is based on the concept of asymptotical compactness. Finally, for the quasiperiodical external force case, the dimension estimates of such a uniform attractor are also obtained.

BTB (broad-complex, tramtrack, and bric-abrac) family proteins are characterized by the presence of a protein–protein interaction BTB domain. BTB proteins have diverse functions, including transcriptional regulation, protein degradation, chromatin remodeling, and cytoskeletal regulation. However, little is known about this gene family in tomato (Solanum lycopersicum), the most important model plant for crop species. In this study, 38 BTB genes were identified based on tomato whole-genome sequence. Phylogenetic analysis of BTB proteins in tomato revealed that SlBTB proteins could be divided into at least 4 subfamilies. The SlBTB proteins contains 1–3 BTB domains, and several other types of functional domains, including KCTD (Potassium channel tetramerization domain-containing), the MATH (meprin and TRAF homology), ANK (Ankyrin repeats), NPR1 (nonexpressor of pathogenesis-related proteins1), NPH3 (Nonphototropic Hypocotyl 3), TAZ zinc finger, C-terminal Kelch, Skp1 and Arm (Armadillo/betacatenin- like repeat) domains are also found in some tomato BTB proteins. Moreover, their expression patterns in tissues/ stages, in response to different abiotic stress treatments and hormones were also investigated. This study provides the first comprehensive analysis of BTB gene family in the tomato genome. The data will undoubtedly be useful for better understanding the potential functions of BTB genes, and their possible roles in mediating hormone cross-talk and abiotic stress in tomato as well as in some other relative species.

In this paper, we study the temporal decay of global weak solutions to the inhomogeneous Hall-magnetohydrodynamic (Hall-MHD) equations. First, an approximation problem and its weak solutions are obtained via the Caffarelli-Kohn-Nirenberg retarded mollification technique. Then, we prove that the approximate solutions satisfy uniform decay estimates. Finally, using the weak convergence method, we construct weak solutions with optimal decay rates to the inhomogeneous Hall-MHD equations.

The novel male sterility line 12-14A of Wucai ( Brassica campestris ) was generated by backcrossing. In this study, morphological,molecular, and cytological analyses were performed to characterize this line. The phenotypes of fl ower organsof 12-14A were diff erent from those of its maintainer line 12-14B, as the fl owers of 12-14A were completely infertile. Molecular analysis confi rmed that the male sterility line 12-14A was classifi ed as the ogu CMS type. An analysis of antherdevelopment in the CMS line demonstrated that two types of abortion occur simultaneously: pollen mother cell abortionand tetrad-to-mononuclear microspore abortion. In addition, the mature anthers of 12-14A showed typical abortive features,such as appearing dry, shrunken, and scaly. A heterosis test of hybrids from CMS 12-14A and four inbred lines was carriedout, and the F 1 hybrids exhibited clear heterosis in plant weight, as well as in the protein, soluble sugar, and vitamin C content,suggesting high yields and high quality potential. These results indicate that this novel CMS line may have powerfulpotential in Wucai hybrid breeding.
