(Submitter supplied) Sunflowers are famous for their ability to track the sun throughout the day, and then reorient at night to face east the following morning. This process, termed heliotropism, is generally believed to be a specialized form of phototropism; however, the underlying mechanism is unknown. To better understand heliotropism we used RNA sequencing to compare the transcriptional profiles of sunflower stems during heliotropism, and blue light-induced phototropism.

(Submitter supplied) Background: Sclerotinia sclerotiorum is one of the most severe fungus diseases in many important crops including sunflower (Helianthus annuus) worldwide. Breeding the resistant varieties are the best strategy to control S. sclerotiorum, however, the molecular regulatory mechanisms of sunflower in response to S. sclerotiorum remain poorly understood. Methods: We performed a leaf transcriptomic analysis to understand the differential defense response to S. more...

(Submitter supplied) Histone modifications are of paramount importance during plant development. Investigating chromatin remodeling in developing oilseeds sheds light on the molecular mechanisms controlling fatty acid metabolism as well as facilitates the identification of new functional regions in oil crop genomes. The present study characterized the epigenetic modifications H3K4me3 in relationship with the expression of fatty acid related-genes and transcription factors in developing sunflower seeds.

(Submitter supplied) Quantitative disease resistance (QDR) is a form of plant immunity conserved across species able to limit infections caused by a broad range of pathogens. QDR has a complex genetic determinism, the bases of which are not fully understood. The number of genes contributing to the QDR response and the extent to which molecular components of the QDR response vary across plant species remain elusive. The fungal pathogen Sclerotinia sclerotiorum, causal agent of white mold disease on hundreds of plant species, triggers QDR responses in host populations. more...
