Rewatering after drought is beneficial to plants subjected to moderate drought stress, and selenium (Se) could increase the tolerance of plants to stressful environment. The role of Se in rewatering of drought-treated wheat seedlings (Triticum aestivum L., cv Hengmai5229) was studied. The objective was to elucidate whether Se could improve recovery of wheat(More)
BACKGROUND A high ratio of blank fruit in hazelnut (Corylus heterophylla Fisch) is a very common phenomenon that causes serious yield losses in northeast China. The development of blank fruit in the Corylus genus is known to be associated with embryo abortion. However, little is known about the molecular mechanisms responsible for embryo abortion during the(More)
Preferential gene-body methylation is a key feature of the mechanism that initiates ovary and ovule development after pollination in hazel. Hazel (Corylus avellana L.) produces edible nuts of great economic value and has unique delayed fertilization characteristics. The ovary in hazel starts to develop only after pollination, and a growth signal from pollen(More)
HIGHLIGHTSIn an abortive ovary of hazel, an integument seldom differentiated and a mature embryo sac never developed.In an abortive ovary of hazel, pollen tube growth was arrested at the style base about 40 days after blooming. Thus, fertilization of the ovule was precluded.Ovary abortion in the four hybrid cultivars was indicated to be associated with(More)
The nut weevil (Curculio nucum) is one of the most important and widespread pests in hazelnut orchards. In order to screen entomopathogenic fungal strains with high virulence against C. nucum, the growth rate, sporulation, and cumulative mortality of different Metarhizium anisopliae and Beauveria bassiana strains were investigated, and the process by which(More)
Rubus idaeus L. is of great economic value. Some varieties of Rubus idaeus have a unique feature of spontaneous rooting from the stem apex. To determine whether DNA methylation is associated with the spontaneous rooting process, variations in the methylation at stem apex during four root developmental stages were investigated, using the(More)
