Biotic and abiotic stress factors consistently threat during different stages of the plant’s life cycle. A complex network of signaling molecules is required to overcome stresses, which is linked to general physiological and molecular processes. Botrytis cinerea is a necrotrophic fungal pathogen that causes grey mold disease on many crops. Apart from B. cinerea, several biotic, abiotic and hormonal stresses have detrimental effects on plant growth and productivity. The aim of this study is to identify the genetic regulations of individual stress types using comparative microarray analyses, and to find out the role of differentially expressed genes in Arabidopsis- …

Biology Theses
Biotic and abiotic stresses critically influence plant survival and growth; survival depends on the ability to correctly sense and react to their environment. Certain environmental stresses must be overcome through careful manipulation of internal levels, and of the resulting signaling cascades. Hormones signaling networks and the crosstalk among each respective hormone signaling pathway are principle for response mediation via transcriptional reprogramming or altered signaling pathways. The long-term objective is to determine how plants sense biotic stresses, and how hormone signaling networks control and direct plant responses to the fungal pathogen Botrytis cinerea. This research aims to identify commonly regulated genes …

Transcriptional Profiling Identifies Potential Genes Associated With Multiple Biotic Stresses In Arabidopsis, Hibatullah Mustafa Al Ashram
Biology Theses
Plants are exposed to many environmental stresses that affect their growth and development. These stresses include biotic stresses (organisms) and abiotic stresses (drought and salinity). Plants respond to these stresses by transcriptional reprogramming and different signaling pathways. Arabidopsis thaliana had shown great sensitivity to the biotic stress: Botrytis cinerea, Alternaria brassicicola, Pseudomonas syringae and the herbivore insect Pieris rapae. The overall goal is to identify common regulated genes that respond to all these biotic stresses to ultimately improve plant stress tolerance in Arabidopsis. The specific aims are to: (1) determine the regulated genes in response to an …
Identification Of Arabidopsis Candidate Genes In Response To Biotic And Abiotic Stresses Using Comparative Microarrays, Salma Omar Al Ameri
Identification Of Arabidopsis Candidate Genes In Response To Biotic And Abiotic Stresses Using Comparative Microarrays, Salma Omar Al Ameri
Theses
Plants have evolved with intricate mechanisms to cope with multiple environmental stresses. To adapt with biotic and abiotic stresses, plant responses involve changes at the cellular and molecular levels. The current study was designed to investigate the effects of combinations of different environmental stresses on the transcriptome level of Arabidopsis thaliana genome using public microarray databases. We investigated the role of cyclopentenones in mediating plant responses to environmental stress through TGA (TGACG motif-binding factor) transcription factor, independently from jasmonic acid. Candidate genes were identified by comparing plants inoculated with Botrytis cinerea or treated with heat, salt or osmotic stress with …
