first report of phomopsis amygdali (del.) tuset & portilla causing galls on common hazel (corylus avellana) twigs in iran
the common hazel (corylus avellana) is a species native to the northwest of iran, with over 12500 ha grown in the province of guilan. in the autumn of 2011, twigs and branch galls of corylus avellana were frequently observed on common hazel trees in eshkevarat orchards in the province of guilan. on hazel trees the galls appear as large nodules initiated on twigs in which tissues developed more ...
متن کاملChange of antioxidant enzymes activity of hazel (Corylus avellana L.) cells by AgNPs.
Elicitation effect of silver nano particles (AgNPs) and triggering of defence system by production of hydrogen peroxide (H2O2) as a signaling molecule in the regulation of the activity of stress-related enzymes and production of Taxol was evaluated in suspension- cultured hazel cells (Corylus avellana L.). The cells were treated with different concentrations of AgNPs (0, 2.5, 5, and 10 ppm), in...
متن کاملExpression and Functional Analysis of WRKY Transcription Factors in Chinese Wild Hazel, Corylus heterophylla Fisch
Plant WRKY transcription factors are known to regulate various biotic and abiotic stress responses. In this study we identified a total of 30 putative WRKY unigenes in a transcriptome dataset of the Chinese wild Hazel, Corylus heterophylla, a species that is noted for its cold tolerance. Thirteen full-length of these ChWRKY genes were cloned and found to encode complete protein sequences, and t...
متن کاملComparison of ultrastructure, pollen tube growth pattern and starch content in developing and abortive ovaries during the progamic phase in hazel
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 insufficient resource availability to supp...
متن کاملOccurrence of Alternaria alternata causing Alternaria blight in pigeonpea in India
Blight symptoms on pigeonpea were observed in alarming proportion since 2009 onwards in Andhra Pradesh state of India. Alternaria blight infected pigeonpea plants were collected from Andhra Pradesh state of India to isolate and characterize the pathogen. The isolate proved pathogenic on pigeonpea cultivar ICPL 87119. Genetic characteristics were analyzed based on the sequence of the rDNA-intern...
