Salicylic acid confers resistance to a biotrophic rust pathogen, Puccinia substriata, in pearl millet (Pennisetum glaucum).

Project description:Studies were undertaken to assess the induction of defence response pathways in pearl millet (Pennisetum glaucum) in response to infection with the leaf rust fungus Puccinia substriata. Pretreatment of pearl millet with salicylic acid (SA) conferred resistance to a virulent isolate of the rust fungus, whereas methyl jasmonate (MeJA) did not significantly reduce infection levels. These results suggest that the SA defence pathway is involved in rust resistance. In order to identify pearl millet genes that are specifically regulated in response to SA and not MeJA, and thus could play a role in resistance to P. substriata, gene expression profiling was performed. Substantial overlap in gene expression responses between the treatments was observed, with MeJA and SA treatments exhibiting 17% co-regulated transcripts. However, 34% of transcripts were differentially expressed in response to SA treatment, but not in response to MeJA treatment. SA-responsive transcripts represented genes involved in SA metabolism, defence response, signal transduction, protection from oxidative stress and photosynthesis. The expression profiles of pearl millet plants after treatment with SA or MeJA were more similar to one another than to the response during a compatible infection with P. substriata. However, some SA-responsive genes were repressed during P. substriata infection, indicating possible manipulation of host responses by the pathogen.

Data of RNA sequencing of pearl millet panicles treated with a high temperature.

Project description:Pearl millet (Pennisetum glaucum) is a cereal crop that can grow and set seeds even under drought, high temperatures and nutrient-poor conditions. Panicles of two pearl millet cultivars that differ in seed-setting rates were exposed to two different high-temperature treatments at three different developmental stages with three replicates, and RNA was prepared from these panicles. The resulting RNA samples were subjected to sequencing with the Illumina NovaSeq 6000 sequencer. The obtained data were 150-base-paired-end reads and were approximately 5 Gb/sample in total. These read data were deposited as those for a project in the NCBI (National Center for Biotechnology Information) BioProject database.
