Research to date indicates that post-transcriptional gene silencing (PTGS) is an effective strategy for the development of stable high-level resistance to Plum pox virus in plum. Field tests in Poland, Romania, and Spain show that after 5–6 years of natural aphid vectored inoculation, trees of the PTGS clone C5 remain virus-free. The effectiveness of transgene-based PTGS for imparting potyvirus...

The Effects of Stone Fruit Extract on the Process of Platelet Aggregation in Vitro. (July 2011) Peter M. deLeeuw Department of Biomedical Sciences Texas A&M University Research Advisor: Dr. Luis Cisneros-Zevallos Department of Horticulture This project attempts to examine the impact stone fruits can have on the clotting of blood in the human body. Plum rich anthocyanin extract (RAE) was added i...

Enophytic fungi were isolated from plum (Prunus domestica) leaves, identified with ITS1 and ITS4 primers, and their antagonistic activity was tested against Monilinia fructicola, which causes brown rot, blossom blight, and twig blight of stone fruits, and Colletotrichum gloeosporioides, which causes anthracnose on a variety of fruit crops. The production of antifungal compounds was determined ...

Stone cell content is thought to be one of the key determinants for fruit quality in pears. However, the molecular mechanism of stone cell development remains poorly understood. In this study, we found that the stone cell clusters (SCCs) distribution and area in 'Dangshan Su' (with abundant stone cells) were higher as compared to 'Lianglizaosu' (low stone cell content bud sport of 'Dangshan Su'...

The aim of present study was to carry out pharmacognostic and physicochemical evaluation of fruits of Gmelina arborea. Fresh fruits and dried powder of the fruits were studied by morphology, microscopy, qualitative chemical test and florescence analysis of powdered drug. Other physicochemical parameters were also performed as per WHO guide lines. The detailed microscopy revealed the presence of...

in recent years, symptoms of virus diseases on stone fruits have been observed in wide range in golestan province. in order to study the important viruses on stone fruits, cherry, plum, nectarine, peach and apricot trees with symptoms such as mosaic, chlorosis, ring spot, shot hole, pale margins in leaves and dwarf in trees, sampling was done during 2005. putative infected plants were tested by...
