Heat shock transcription factors (Hsfs), which act as important transcriptional regulatory proteins in eukaryotes, play a central role in controlling the expression of heat-responsive genes. At present, the genomes of Chinese white pear (‘Dangshansuli’) and five other Rosaceae fruit crops have been fully sequenced. However, information about the Hsfs gene(More)
The study was conducted to determine the effects of iron glycine chelate (Fe-Gly) on growth, tissue mineral concentrations, fecal mineral excretion, and liver antioxidant enzyme activities in broilers. A total of 360 1-day-old commercial broilers (Ross × Ross) were randomly allotted to six dietary treatments with six replications of ten chicks per(More)
This study indicated that Ca 2+ , ROS and actin filaments were involved with CaM in regulating pollen tube growth and providing a potential way for overcoming pear self-incompatibility. Calmodulin (CaM) has been associated with various physiological and developmental processes in plants, including pollen tube growth. In this study, we showed that CaM(More)
To examine the biochemical metabolism of aroma volatiles derived from fatty acids, pear fruits were incubated in vitro with metabolic precursors of these compounds. Aroma volatiles, especially esters, were significantly increased, both qualitatively and quantitatively, in pear fruits fed on fatty acid metabolic precursors. Cultivars having different flavor(More)
Pear is a tree fruit species with worldwide distribution and belongs to the Rosaceae family. In this study, the phloem unloading pathway in pear (Pyrus bretschneideri ‘Yali’) fruit was investigated using transmission electron microscopy coupled with a symplasmic tracer dye, carboxyfluorescein diacetate (CFDA). Structurally, the sieve element-companion cell(More)
Our previous studies showed that kisspeptin-10 (Kp-10) injected in vivo can markedly increase lipid anabolism in liver of quails. In order to investigate the direct effect of Kp-10 on lipid metabolism of hepatocytes in birds, cells were separated from embryos livers and cultured in vitro with 0, 100 and 1,000 nM Kp-10, respectively. The results showed that(More)
Glutamate-like receptors (GLRs) is a highly conserved family of ligand-gated ion channels, which have been associated with various physiological and developmental processes. Here, we investigated the evolutionary pattern of GLRs in plants. We observed that tandem duplications occupied the largest proportion of the plant GLR gene family expansion. Based on a(More)
The monovalent cation proton antiporters (CPAs) play essential roles in plant nutrition, development, and signal transduction by regulating ion and pH homeostasis of the cell. The CPAs of plants include the Na+/H+ exchanger, K+ efflux antiporter, and cation/H+ exchanger families. However, currently, little is known about the CPA genes in Rosaceae species.(More)
Yellow stripe-like (YSL) family transporters, belonging to the oligopeptide transporter family, are significant iron transport proteins. In this study, we provided a genome-wide identification and analysis of the YSL gene family in Pyrus bretschneideri. We found eight YSL gene members in pear, clustered into four main groups in the phylogenetic tree.(More)
Recent sequencing of the Oriental pear (P. bretschneideri Rehd.) genome and the availability of the draft genome sequence of Occidental pear (P. communis L.), has provided a good opportunity to characterize the abundance, distribution, timing, and evolution of long terminal repeat retrotransposons (LTR-RTs) in these two important fruit plants. Here, a total(More)
