(Submitter supplied) Gray leaf spot (GLS) disease of maize can be caused by either of two sibling fungal species Cercospora zeina or Cercospora zeae-maydis. These species differ in geographical distribution, for example to date only C. zeina is associated with GLS in African countries, such as South Africa. Maize inbred line B73, which is susceptible to GLS, was planted in the field, and subjected to natural infection with C. more...

(Submitter supplied) Gray leaf spot (GLS) disease of maize can be caused by either of two sibling fungal species Cercospora zeina or Cercospora zeae-maydis. These species differ in geographical distribution, for example to date only C. zeina is associated with GLS in Africa. C. zeae-maydis isolates produce the phytotoxin cercosporin in vitro, whereas C. zeina does not. C.zeina was grown in different in vitro conditions to determine if the cercosporin biosynthesis genes were expressed. more...

(Submitter supplied) Arabidopsis fc2-1 mutants fail to properly de-etiolate after a prolonged period in the dark. Our goal was to monitor whole genome expression during the first 2 hours of de-etiolation to determine the cuase of this growth arrest. In comparison with other mutants that also affect de-etiolation, we identified a subset of genes specifically regulated by FC2 function during de-etiolation.

(Submitter supplied) Rapid responses to biotic and abiotic insults are crucial for plant survival. We examined the very early (10 min) wound transcriptome in order to increase our understanding regarding this critical intial phase of the plant response to stress. Our analysis revealed a rapid induction of stress-related transcripts that was distinct from the long term events which are dominated by jasmonic pathway responses. more...

(Submitter supplied) We used the flu mutant of Arabidopsis to detail gene expression in response to singlet oxygen. The conditional flu mutant of Arabidopsis accumulates excess protochlorophyllide in the dark within chloroplast membranes that upon illumination acts as a photosensitizer and generates singlet oxygen. Immediately after the release of singlet oxygen mature flu plants stop growing, whereas seedlings bleach and die. more...

(Submitter supplied) We used microarrays to detail Arabidopsis gene expression in response to paraquat, a herbicide that acts as a terminal oxidant of photosystem I that in the light leads to the enhanced generation of superoxide and hydrogen peroxide inside plastids. Within a few hours after paraquat treatment changes in nuclear gene expression occur. Distinct sets of genes were activated that were different from those induced by another reactive oxygen species, singlet oxygen. more...

Analysis of Ler ecotype rosette leaves for up to 4 hours following treatment with paraquat. Paraquat is an herbicide that acts as a terminal oxidant of photosystem I. In light paraquat reduces oxygen to the superoxide radical, which subsequently dismutates to hydrogen peroxide.

(Submitter supplied) We used the flu mutant of Arabidopsis and a transgenic line that overexpresses the thylakoid-bound ascorbate peroxidase (tAPX) to address the interactions between different reactive oxygen species (ROS) signaling pathways. The conditional flu mutant of Arabidopsis accumulates excess protochlorophyllide in the dark within chloroplast membranes that upon illumination acts as a photosensitizer and generates singlet oxygen (1O2). more...
