BACKGROUND Bt-cry1Ac gene has been reputedly effective against Helicoverpa armigera a notorious lepidopteran pest. Reports on the expression of full-length and truncated cry1Ac genes in plants for effective resistance against Helicoverpa sp. have been documented however, their performance is still ambiguous. Moreover, the question remains to be addressed that truncation of 3' end of the native ...

• oxdc gene from flammulina velutipes was used to generate transgenic tomato plants. Transgenic T 1 lines showed a significant delay in symptom development. higher survival percentage witches’ broom disease. The P16 line decreased production of H 2 O the presence oxalic acid. Witches’ disease progression reduced by gene. which affects cacao tree ( Theobroma L.) is caused hemibiotrophic fungus M...

The tomato I-3 and I-7 genes confer resistance to Fusarium oxysporum f. sp. lycopersici (Fol) race 3 and were introgressed into the cultivated tomato, Solanum lycopersicum, from the wild relative Solanum pennellii. I-3 has been identified previously on chromosome 7 and encodes an S-receptor-like kinase, but little is known about I-7. Molecular markers have been developed for the marker-assisted...

Abstract Tomato production is influenced by shoot branching, which controlled different hormones. Here we produced tomato plants overexpressing the cytokinin-deactivating gene CYTOKININ OXYDASE 2 ( CKX2 ). -overexpressing (CKX2-OE) showed an excessive growth of axillary shoots, opposite phenotype expected for with reduced cytokinin content, as evidenced LC-MS analysis and ARR5-GUS staining. The...

The genome of the geminivirus tomato golden mosaic virus (TGMV) consists of two circular DNA molecules designated as components A and B. We have constructed Nicotiana benthamiana plants that are transgenic for the three overlapping open reading frames, AL1, AL2, and AL3, from the left side of TGMV A. In the transgenic plants, the AL open reading frames are under the control of the cauliflower m...

The cucumber expansin 10 (CsEXP10) gene was previously cloned from young cucumber fruits but its role has not been defined. To determine the role of this gene in plant growth and development, a CsEXP10 gene transformation system was established. The open reading frame of the gene was inserted behind the CaMV35S promoter of vector pCAMBIA1301, and the construct was introduced into tomato plants ...
