In plants, it is possible to induce heritable transcriptional gene silencing (TGS) via RNA-directed DNA methylation (RdDM) using artificially synthesized small RNA (siRNA) homologous to the 5'-flanking region of the target gene. As the siRNA signal with a specific RNA determinant moves through plasmodesmata and sieve elements, we attempted to induce TGS of a transgene and an endogenous gene of ...

'Jones Hybrid' hickory is an accession in the National Collection of Genetic Resources for Pecans and Hickories for which information about origin, identity and characteristics is very incomplete. Phenotypic and genetic profiles, when examined in the context of historic literature, provide evidence that the accession in question is 'Siers' a cultivar of Carya × laneyi (an interspecific hybrid b...

A protocol for micrografting shoot tips harvested from in vitro shoot cultures directly to transplanted rootstock plants in the greenhouse was developed. Shoot tips of the apple (Malus domestica) cultivars Golden Delicious, Granny Smith and Fuji clone, Nagafu12, were harvested, stored in a water bath then prepared for grafting by cutting the stem immediately below the tip into a wedge shape lea...

the effects of rootstocks such as 'sour orange' (citrus aurantium l. var. ‘yerli’), 'carrizo' and 'troyer citranges' (citrus sinensis osb. x poncirus trifoliata raf), 'smooth flat seville sour orange' (citrus spp. hybrid of uncertain origin), 'brazilian sour orange' (citrus aurantiam l. var. ‘brasilian’), 'volkameriana' (citrus volkameriana tan. and pasq.) and 'calamondin' (possibly citrus reti...

Pistachio is the most important nut that is produced in Iran. Little research has been done to examine the effect of UCB1-hybride rootstock plants as tissue culture for pistachios (2011 in Toba company).This study aims to evaluate three pistachio varieties on UCB1 hybrid rootstock.  The experiment was conducted as a randomized complete block design with three treatment groups (including Ohadi, ...

abstract in this paper, the effect of foreign sector macro-variable on inflation dynamics and firms’ pricing behavior has been investigated in the context of a small open economy new keynesian phillips curve. this curve is derived and estimated for a developing oil-exporting economy suffering from dutch disease. this version of nkpc is an extension of leith and malley’s (2007) small open econom...

The primary goal of this proposal is to develop novel regeneration technologies needed to engineer walnut rootstocks for pest and disease resistance. The productivity of the walnut industry of California is dependent the availability of superior rootstocks to combat soil disease and pest problems. Individual selections displaying resistance to either Phytophthora crown and root rots or to root ...

Prior research identified cultural and biologically active methods, which when applied independently, provide partial control of the pathogen complex that incites apple replant disease and enhanced yield of Gala on M.26 rootstock in orchard trials. In previous studies (Mazzola et al., 2001. Phytopathology 91:673-679), soil amendments were identified that effectively controlled certain elements ...

Shi, Biying. M.S., Purdue University, May 2015. Growth Parameters for 'Golden Delicious' Apple Trees (Malus × domestica Borkh.). Major Professor: Peter Hirst. High yield and high quality of tree fruit result from appropriate orchard design and management practices. This requires an accurate knowledge of vegetative growth, branching, and flowering processes of fruit trees. Tree development knowl...
