Several taxa of Cactaceae are endangered by overcollection for commercial purposes, and most of the family is included in the Convention on International Trade in Endangered Species of Fauna and Flora (CITES). Micropropagation may play a key role to keep the pressure off wild populations and contribute to ex situ conservation of endangered taxa. One of the limits of micropropagation is the spec...

Hickory (Carya cathayensis), a tree with high nutritional and economic value, is widely cultivated in China. Grafting greatly reduces the juvenile phase length and makes the large scale cultivation of hickory possible. To reveal the response mechanisms of this species to grafting, we employed a proteomics-based approach to identify differentially expressed proteins in the graft unions during th...

One of the key factors that defines plant form is the regulation of when and where branches develop. The diversity of form observed in nature results, in part, from variation in the regulation of branching between species. Two CAROTENOID CLEAVAGE DIOXYGENASE (CCD) genes, CCD7 and CCD8, are required for the production of a branch-suppressing plant hormone. Here, we report that the decreased apic...

Compared to other techniques of propagation, grafting is the most successful and feasible technique for asexual propagation of walnut plants. There is little information about graft union formation in walnut. Therefore, the objective of this study was to evaluate histological events during graft union formation in Juglans regia L. cv. Chandler scions when minigrafted on the one-year-old seedlin...

The use of scions grafted onto passionfruit vines has become an alternative to their cultivation in areas with a history fusariosis. However, the combinations between graft and rootstock can influence on productivity longevity farm. objective was evaluate mortality cv BRS Rubi do Cerrado three species Terra Nova Norte-MT. design randomized block 4 treatments (BRS-RC) seedling plant along those ...

In subtropical regions, tomato (Solanum lycopersicum) is mainly produced in autumn and winter. To enhance the off-season production of tomato, summer cultivation has become a prime objective. Grafting scions onto eggplant melongena) rootstocks key method to overcome difficulties summer. this study, we collected seedling growth data over six growing seasons Taiwan established models by employing...

Walnut blackline disease caused by the cherry leafroll virus (CLRV) causes fatal necrosis at the union between English walnut scions and hypersensitive rootstocks. All English walnut cultivars tested so far are susceptible to blackline girdling. A breeding program for developing a blackline resistant Englishwalnut cultivarwas begun in 1983. The time requiredto breed an English walnut cultivar t...

Vitis vinifera scions are commonly grafted onto rootstocks of other grape species to influence scion vigour and provide resistance to soil-borne pests and abiotic stress; however, the mechanisms by which rootstocks affect scion physiology remain unknown. This study characterized the hydraulic physiology of Vitis rootstocks that vary in vigour classification by investigating aquaporin (VvPIP) ge...

The phloem's role as a tissue responsible for the distribution of photoassimilates and nutrients among the various organs of higher plants has long been recognized. Recent studies have established that numerous proteins and mRNA molecules are also present in the phloem translocation stream; however, limited information is available on the identity of transcripts present within the phloem sap. I...

Ecophysiological characteristics of "Ahmadaghaii" "Ohadi" "Kallehghuchi" cultivars (as scions) on four pistachio rootstocks (Pistacia vera Cv. Badami riz, P. vera Cv. Sarakhs, P. atlantica sub sp. Mutica, P. atlantica sub sp. Atlantica) were evaluated during the spring and summer seasons of 2005 in the Iran's Pistachio Research Institute (IPRI). Ecophysiological characteristics such as photosyn...
