Persian walnut (Juglans regia L., Juglandaceae), one of the essential nut crops, is affected by different diseases, including mite attacks which result in gall and erineum formation. As proportion leaf area covered galls or typically relatively low, impact on tree photosynthetic productivity often considered minor, no pest control management usually suggested. However, effect erineum-forming mi...

Well-preserved silicified woods from a site near the town of Post, Oregon, western USA, provide insights into late Eocene vegetation and climate ca. 36 million years data for comparing with both older younger wood floras regionally globally. The composition this flora, taken consideration along taxa identified fruits seeds same locality, provides more complete picture former vegetation. We reco...

we have studied the medicinal plants of ghasemloo and then surveyed the usagepercentage of different parts from each specimen for the medicinal or diet consumptions atthree sites from the adjacent villages of ghasemloo valley, villages of west and eastazerbaijan including 17 questioners. during two years, the medicinal plants that have beencollected and provided as herbarium specimens were reco...

Abstract Pterocarya fraxinifolia , native to the southern Caucasus and adjacent areas, has been widely introduced in Europe. In this study, we investigate following: (1) How did its current distribution form? (2) What are past, current, future suitable habitats of P. ? (3) is best conservation approach? Ecological niche modeling was applied determine climatic demands project climatically areas ...

Morella rubra (Myricaceae), also known as Chinese bayberry, is an economically important, subtropical, evergreen fruit tree. The phylogenetic placement of Myricaceae within Fagales and the origin of Chinese bayberry's domestication are still unresolved. In this study, we report the chloroplast (cp) genome of M. rubra and take advantage of several previously reported chloroplast genomes from rel...

The black pecan aphid, Melanocallis caryaefoliae (Davis) (Hemiptera: Aphididae), is a foliar feeder of pecan, Carya illinoinensis (Wangenh.) K. Koch (Juglandaceae). The pest causes chlorosis of leaflet lamina, physiological damage to foliage and trees, and commonly limits the profitability of commercial pecan orchard enterprises. However, key aspects of this host-pest interaction are poorly und...

Phylogenetic analyses of extant species of Juglans (Juglandaceae) with the New and Old World distributions were performed using five cpDNA intergenic spacer (IGS) sequences (trnT-trnF, psbA-trnH, atpB-rbcL, trnV-16S rRNA, and trnS-trnfM) to elucidate the origin, diversification, historical biogeography, and evolutionary relationships within the genus. Overall, 3848 characters were sampled, yiel...
