Quantification Of Salicylic Acid And Analysis Of Defense-Related Genes In The Moss Physcomitrella Patens, Ryan Jospeh Eller
Quantification Of Salicylic Acid And Analysis Of Defense-Related Genes In The Moss Physcomitrella Patens, Ryan Jospeh Eller
Undergraduate Honors Thesis Collection
The moss Physcomitrella patens is an invaluable non-vascular plant specimen to study genetic interactions because its entire genome is sequenced. Therefore, any gene studies conducted in more evolved vascular plants can be transferred to this specimen fairly easily by utilizing comparative genomic techniques made possible through the National Center for Biotechnology Information (NCBI). The questions that were asked in this thesis revolved around the Systemic Acquired Resistance, or the basic mechanism that allows plants to protect themselves against biotic and abiotic stressors. Two main approaches were used to analyze this complex system. First, an analytical chemistry technique was used to …
The Influence Of Light On Bryophytes And Their Response To Pathogen Infection: A Story Of Mnium Cuspidatum And Physcomitrella Patens, Bryce James Fawcett
The Influence Of Light On Bryophytes And Their Response To Pathogen Infection: A Story Of Mnium Cuspidatum And Physcomitrella Patens, Bryce James Fawcett
Undergraduate Honors Thesis Collection
The influence of light on non-vascular plant-pathogen interactions were studied in two moss species, Mnium cuspidatum and Physcomitrella patens, using a fungal pathogen, Pythium irregulare, and a commonly used pathogenic elicitor (beta-glucan). The findings of this study suggest that light does playa role in moss defense but speci fic mechanisms remain unclear. In P. patens it was found that the defense gene AOe was up-regulated in the light compared to the dark when treated with beta-glucan elicitor. A phenotypic study of M. cuspidatum revealed that P. irregulare will infect and M cuspidatum will subsequently mount a defense response. Unexpectedly, samples …
