The F-box protein family is a large family that is characterized by conserved F-box domains of approximately 40–50 amino acids in the N-terminus. F-box proteins participate in diverse cellular processes, such as development of floral organs, signal transduction and response to stress, primarily as a component of the Skp1-cullin-F-box (SCF) complex. In this(More)
The role of LTO1/ At VKOR-DsbA in ROS homeostasis and in redox regulation of cysteine-containing proteins in chloroplast was studied in lto1 - 2 mutant, and a potential target of LTO1 was captured. A chloroplast membrane protein LTO1/AtVKOR-DsbA encoded by the gene At4g35760 was recently found to be an oxidoreductase and involved in assembly of PSII. Here,(More)
Homologs of vitamin K epoxide reductase (VKOR) exist widely in plants. However, only VKOR of Arabidopsis thaliana has been the subject of many studies to date. In the present study, the coding region of a VKOR from Solanum lyco-persicum (JF951971 in GenBank) was cloned; it contained a membrane domain (VKOR domain) and an additional soluble thioredoxin-like(More)
Thylakoid protein vitamin K epoxide reductase (AtVKOR/LTO1) is involved in oxidoreduction. The deficiency of this compound causes pleiotropic defects in Arabidopsis thaliana, such as severely stunted growth, smaller sized leaves, and delay of flowering. Transgenic complementation of wild-type AtVKOR (VKORWT) to vkor mutant lines ultimately demonstrates that(More)
Low temperature is a major environmental constraint on the production of apples worldwide. An apple rootstock with high cold tolerance was selected to identify genes related to stress tolerance. The transcriptional profiles of the genes in the leaves were examined after various intervals of exposure to cold stress. We obtained three libraries of 14,219,(More)
Tubby-like proteins (TLPs), which have a highly conserved β barrel tubby domain, have been found to be associated with some animal-specific characteristics. In the plant kingdom, more than 10 TLP family members were identified in Arabidopsis, rice and maize, and they were found to be involved in responses to stress. The publication of the apple genome makes(More)
Lung cancer has become one of the leading causes of cancer mortality worldwide, and non-small-cell lung cancer (NSCLC) accounts for ~85% of all lung cancer cases. Currently, platinum-based chemotherapy drugs, including cisplatin and carboplatin, are the most effective treatment for NSCLC. However, the clinical efficacy of chemotherapy is markedly reduced(More)
In this article, we investigate the fourth-order four-point nonho-mogeneous Sturm-Liouville boundary-value problem u (4) (t) = f (t, u(t)), t ∈ [0, 1], αu(0) − βu (0) = γu(1) + δu (1) = 0, au (ξ 1) − bu (ξ 1) = −λ, cu (ξ 2) + du (ξ 2) = −µ, where 0 ≤ ξ 1 < ξ 2 ≤ 1 and λ and µ are nonnegative parameters. We obtain sufficient conditions for the existence and(More)
