Transcript analysis of some defense genes of tomato in response to host and non-host bacterial pathogens
The transcript levels of six defense genes including pathogenesis-related gene 1 (PR-1), pathogenesis-related gene 2 (PR-2), pathogenesis-related gene 5 (PR-5), lipoxygenase (LOX), phenylalanine ammonia-lyase (PAL) and catalase (CAT) were investigated in tomato plants inoculated with Xanthomonas axonopodis pv. phaseoli as a non-host pathogen and X. euvesicatoria as a host pathogen. Activation o...
متن کاملHost resistance to ectoparasites.
Examples of immunological reactions to arthropod parasites include responses by hosts to the following stimuli: excretory and secretory antigens produced by myiasis-producing larvae or skin-dwelling (mange) mites salivary antigens of blood-sucking arthropods. In many cases, these are hypersensitivity reactions, which often appear not to produce very deleterious effects on the parasites. However...
متن کاملOverlapping sets of transcripts from host and non-host interactions of tomato are expressed early during non-host resistance
Natural immunity present in all the plants against most of the pathogens is called as non-host resistance (NHR). Although NHR is most durable form of resistance, it was less studied compared to other forms of resistance. We compared transcriptional changes in tomato during non-host (Magnaporthe grisea) and compatible (Alternaria alternata f. sp. lycopersici) interactions using Agilent microarra...
متن کاملAbscisic acid enhances resistance to Alternaria solani in tomato seedlings.
The plant hormone abscisic acid (ABA) is an important regulator in many aspects of plant growth and development, as well as stress resistance. Here, we investigated the effects of exogenous ABA application on the interaction between tomato (Solanum lycopersicon L.) and Alternaria solani (early blight). Foliar spraying of 7.58 μM ABA was effective in reducing disease severity in tomato plants. P...
متن کاملApproaches to assessing host resistance.
There is increasing evidence that chronic, subclinical exposure to certain environmental pollutants may upset immune responsiveness and alter susceptibility of animals to infectious agents. Environmental chemicals or drugs may affect diverse aspects of the immune system, leading to immunosuppression, immunopotentiation, hypersensitivity or perturbed innate host resistance. A variety of infectio...
