Genes, Vol. 9, Pages 224: Genome Wide Identification, Evolutionary, and Expression Analysis of VQ Genes from Two Pyrus Species
ongping Cai
The VQ motif-containing gene, a member of the plant-specific genes, is involved in the plant developmental process and various stress responses. The VQ motif-containing gene family has been studied in several plants, such as rice (Oryza sativa), maize (Zea mays), and Arabidopsis (Arabidopsis thaliana). However, no systematic study has been performed in Pyrus species, which have important economic value. In our study, we identified 41 and 28 VQ motif-containing genes in Pyrus bretschneideri and Pyrus communis, respectively. Phylogenetic trees were calculated using A. thaliana and O. sativa VQ motif-containin...

Characterization and overexpression of RHO1 from Cryptococcus laurentii ZJU10 activates CWI signaling pathway on enhancing the inhibition of blue mold on pears.
Abstract
Results from this study explored the inhibitory effect of RHO1 gene (GenBank accession number KY859864) from the antagonistic yeast, Cryptococcus laurentii ZJU10, on the control of Penicillium expansum in pear fruit and its possible mechanism involved. The RHO1 gene was successfully cloned and overexpressed in Saccharomyces cerevisiae. Sequence analysis showed high similarity with Rho family proteins, implying a primary role of Rho1 in the cell wall integrity (CWI) signaling pathway. Gene expression of RHO1 and other five CWI-related genes (including Pkc1, Rlm1, Fks1, Fks2 and Chs3) were significa...

Characterization and expression of the ABC family (G group) in ‘Dangshansuli’ pear (Pyrus bretschneideri Rehd.) and its russet mutant
Abstract The plant genes encoding ABCGs that have been identified to date play a role in suberin formation in response to abiotic and biotic stress. In the present study, 80 ABCG genes were identified in ‘ Dangshansuli ’ Chinese white pear and designated as PbABCGs. Based on the structural characteristics and phylogenetic analysis, the PbABCG family genes could be classified into seven main groups: classes A-G. Segmental and dispersed duplications were the primary forces underlying the PbABCG gene family expansion in ‘ Dangshansuli ’ pear. Most of the PbABCG duplicated gene pairs date to the recent whole-genome d...

The changes of intracellular calcium concentration and distribution in the hard end pear (Pyrus pyrifolia cv. 'Whangkeumbae') fruit.
In this study, we explored the causes of hard end disorder in pear fruit in relation to calcium deficiency. During fruit development, the ratio of Ca/N, Ca/K, Ca/Mg and the content of B were significantly lower in the hard end fruit as compared to normal fruit. However, no calcium deficiency was detected in the soil and leaves of the orchard where the hard end fruit were located. Additionally, the Ca2+ influx in the calyx of hard end fruit was lower than that of normal fruit at 90 d after anthesis. The free Ca2+ and storage Ca2+ in the flesh cells of hard end fruit were less than that of normal fruit during fruit developme...
