Forty-five Xanthomonas arboricola pv. juglandis (Xaj) strains originating from Juglans regia cultivation in different countries were molecularly typed by means of MultiLocus Sequence Typing (MLST), using acnB, gapA, gyrB and rpoD gene fragments. A total of 2.5 kilobases was used to infer the phylogenetic relationship among the strains and possible recombination events. Haplotype diversity, link...

Bacterial blight (Xanthomonas arboricola pv.juglandis) is one of the main diseases of walnut that reduce the yield in the central, western and northern regions of Iran. This disease was first reported form, Qazvin and Mazandaran, then widely reported from northern, central and western provinces. To identify the cause of the disease in different provinces, infected leaves collected from Alborze,...

The oviposition-preference–offspring-performance hypothesis predicts that female insects should prefer to deposit clutches on or in hosts that maximize offspring performance. An important assumption behind this prediction is that female fitness is tightly correlated with the fitness of any one offspring. In this study, we evaluate offspring performance in the walnut fly, Rhagoletis juglandis Cr...

Testes size often predicts the winner during episodes of sperm competition. However, little is known about the source of nutrients allocated to testes development, or testes plasticity under varying nutrient availability. Among many holometabolous insects, metabolic resources can derive from the larval or adult diet. Distinguishing the source of nutrients allocated to testes can shed light on l...

Prior experience with conspecifics or essential resources, as well as physiological condition, can have important influences on an animal’s reproductive behavior. While effects of experience and physiological state (such as reproductive condition) are generally treated separately in theoretical discussions, they often interact. Noprevious study has attempted todistinguish effects of experience ...

BACKGROUND To monitor the richness in microbial inhabitants in the phyllosphere of apple trees cultivated under various cultural and environmental conditions, we developed an oligo-DNA macroarray for major pathogenic and non-pathogenic fungi and bacteria inhabiting the phyllosphere of apple trees. METHODS AND FINDINGS First, we isolated culturable fungi and bacteria from apple orchards by an ...

Marssonina brunnea causes a major disease that limits poplar growth. Lignin and lignan play essential roles in protecting plants from various biological stresses. Dirigent (DIR) proteins are thought to control the stereoselective coupling of coniferyl alcohol formation lignin. DIR family members have been well studied several plant species, but no previous detailed genome-wide analysis has carr...
