This experiment was conducted to test the effects of foliar application of progesterone on the photochemical efficiency of photosystem II (PSII) and photosynthetic rate in wheat flag leaves subjected to cross-stress of heat and high light during grain-filling stage. The results showed that progesterone pretreatment increased the activities of superoxide(More)
In this study, we investigated the effects of foliar applied salicylic acid (SA) on protecting wheat (Triticum aestivum) from heat and high light stress during the grain filling stage. Specifically, the Photosystem II (PSII) photochemistry of wheat flag leaves under the treatment of SA was studied as indicators for stress response. Our results indicated(More)
Mutational analysis has established that the cytoplasmic tail of the integrin beta 3 subunit binds c-Src (termed as Src in this study) and is critical for bidirectional integrin signaling. Here we show in washed human platelets that a cell-permeable, myristoylated RGT peptide (myr-RGT) corresponding to the integrin beta 3 C-terminal sequence(More)
Fanconi anemia (FA) is an autosomal or X-linked recessive disorder characterized by chromosomal instability, bone marrow failure, cancer susceptibility, and a profound sensitivity to agents that produce DNA interstrand cross-link (ICL). To date, 15 genes have been identified that, when mutated, result in FA or an FA-like syndrome. It is believed that(More)
We examined the effects of 2,4-epibrassinolide (EBR) application on photosynthesis, antioxidant enzyme activity, and Rubisco activase (RCA) gene expression in wheat (Triticum aestivum L.) seedlings under a combination of drought and heat stress. The net photosynthetic rates (Pn) of wheat seedlings decreased significantly, the photosynthetic capability was(More)
A type of 1,1'-binaphthyl-based imidazolium chemosensor module has been synthesized for the highly selective recognition of tryptophan (Trp) among the eleven alpha-amino acids investigated in aqueous solutions via synergistic effects of multiple hydrogen bonding and electrostatic interactions. These results have demonstrated that the C-2 hydrogen atom of(More)
The chiral tris-monodentate imidazolinyl ligands 1 a-c exhibit a strong tendency to form the discrete, helical [2+3] nanocages 3 ([1(2).2(3)]) with tartaric acids 2. Circular dichroism (CD) spectra and theoretical calculations reveal that supramolecular handedness of capsulelike architectures is determined only by the chirality of the imidazolinyl ligands(More)
