Abstract Citrus tristeza virus (CTV) is found worldwide wherever citrus cultivated, causing disease resulting in significant yield losses and sometimes the death of plant. Transgenic plants encoding CTV gene sequences have shown to exhibit pathogen-derived resistance CTV. Exogenous application double-stranded RNA (dsRNA) an established strategy for plant control, making this method attractive a...

Agrobacterium mediated transformation in nature is the cause of development diseases: crown galls and hairy roots. These neoplasms are transgenic tissues on a non-transgenic plant. However, nature, full-fledged GMOs arise, containing agrobacterial transgenes every cell transmitting them series sexual generations. plants called naturally or natural GMOs. Over past 3 years, list GMO species has b...

Plant lodging resistance is an important integrative agronomic trait of grain yield and quality in crops. Although extensin proteins are tightly associated with plant cell growth and cell wall construction, little has yet been reported about their impacts on plant lodging resistance. In this study, we isolated a novel extensin-like (OsEXTL) gene in rice, and selected transgenic rice plants that...

Cotton (Gossypium hirsutum L.)  is an important fiber crop in Iran, cultivated on 150000-200000 ha of land.  In Iran the estimated loss due to the insect pest is more than 30%. Traditionally, pests are controlled by 10-12 times spraying per growing season of environmentally harmful chemical insecticides (e.g. endosulfan and/or methosystox). In order to produce transgenic cotton resistance to in...

Torenia is an annual plant of the family Scrophulariaceae that is used as an ornamental summer bedding plant. Torenia is also an experimental plant with several useful characteristics, i.e., ease of genetic transformation, ability to differentiate adventitious structures, protruding embryo sac, and capacity for in vitro flowering. Genetic transformation of torenia was first reported in 1995, an...

Transgenic Nicotiana tabacum plants expressing Aspergillus niger b-glucosidase (EC 3.2.1.21) gene (BGL1) in different subcellular compartments [cell wall (Tcw), endoplasmic reticulum (Ter), and vacuole (Tvc)] were analyzed to study the effects of BGL1 localization on plant growth and plant–insect interaction. Transgenic and non-transgenic plants were grown and characterized in a greenhouse with...

under osmotic stresses, proline accumulation is an important response of plants to these conditions. proline is a compatible osmolyte which affects many cellular and molecular aspects of plant in both normal and stressful situations. proline is shown to be involved in plant development in normal condition and in conferring resistance to plant under biotic and abiotic stresses. therefore, many s...

it has been more than half a century that plant geneticists and breeders have been trying to assemble a combinationof genes in crop plants, in order to make them as suitable and productive as possible. plant transformation technology incrop plants was first undertakenin the 1980s based on the ability of foreign gene integration into host plant genome andregeneration of transformed plant cells i...
