OBJECTIVE
To isolate and identify endophytic fungi from Malus sieboldii, and detect cytotoxicity, protease inhibition and antifungal activities of their crude extracts.
METHODS
The fungi were identified with the aid of morphology or Internal Transcribed Spacer (ITS) rDNA molecular methods. Fungal
The AvrRpt2 protein of the phytopathogenic bacterium Erwinia amylovora (AvrRpt2EA) is a secreted type III effector protein, which is recognised by the FB_MR5 resistance protein of Malus × robusta 5, the only identified resistance protein from a Malus species preventing E. amylovora
Phytocystatins are a well-characterized class of naturally occurring protease inhibitors that prevent the catalysis of papain-like cysteine proteases. The action of cystatins in stress tolerance has been studied intensively, but relatively little is known about their functions in plants during leaf
Phytocystatins (PhyCys) comprise a group of inhibitors for cysteine proteinases in plants. They play a wide range of important roles in regulating endogenous processes and protecting plants against various environmental stresses, but the underlying mechanisms remain largely unknown. Here, we
In order to compare transcription profiles in cultivars of Malus domestica that are differentially sensitive to apple scab (Venturia inaequalis), two cDNA libraries were constructed using the suppression subtractive hybridization (SSH) method. Subtraction hybridization was performed between cDNAs
The conversion of inactive pro-polyphenol oxidases (pro-PPOs) into the active enzyme results from the proteolytic cleavage of its C-terminal domain. Herein, a peptide-mediated cleavage process that activates pro-MdPPO1 (Malus domestica) is reported. Mass spectrometry, mutagenesis studies, and X-ray
A major protease present in dormant bark tissues of the apple (Malus domestica Borkh. cv. "Golden Delicious") was partially purified by hemoglobin-coupled Sepharose column chromatography. The protease active at pH 4.6 and at temperatures of 30 to 50 C was found to be sulfhydryl-dependent.
1-Aminocyclopropane-1-carboxylic acid (ACC) oxidase (ACCO) catalyses the final step in ethylene biosynthesis converting ACC to ethylene, cyanide, CO2, dehydroascorbate and water with inputs of Fe(II), ascorbate, bicarbonate (as activators) and oxygen. Cyanide activates ACCO. A 'nest' comprising
In order to understand molecular events during fruit development and provide genetic resources for molecular breeding, 430 expressed sequence tags (ESTs) were generated from randomly selected clones of cDNA libraries prepared from young fruits, peels of mature fruits, and carpels of the Fuji apple
