(Submitter supplied) Plants have evolved a tightly regulated and inducible immune system to resist pathogen attack. After the initial contact with the pathogen, plants are significantly more resistant to future challenges, even from unrelated pathogens, an event known as systemic acquired resistance (SAR). In plants polyamines are involved in the regulation and establishment of the defense response by modulating their metabolism, specifically their biosynthesis, conjugation and catabolism. more...

(Submitter supplied) Pathogens infection exerts major effects on gene expression, which is reconfigured to raise the defences of the attacked plant. In the recent years the establishment of an hypoxic environment during Botrytis infection was described. We used the pentuple erfVII mutant to evaluate the contribution of ERFVII members to plant reaction to Botrytis and their effect on gene expression.

(Submitter supplied) Explosives are widespread, toxic and persistent environmental pollutants. 2,4-Dinitroanisole (DNAN) is being phased in to replace 2,4,6-trinitrotoluene (TNT) in munitions. Here we demonstrate that only low levels of DNAN are detoxified in Arabidopsis, leaving it to remain as a substrate for monodehydroascorbate reductase 6 mediated chronic phytotoxicity. Enhancing the potential for environmental toxicity, DNAN is readily transported to the aerial tissues exposing this toxin to herbivores and the wider food chain.

(Submitter supplied) Plants possess high potential for somatic cell reprogramming. Despite extensive studies on the molecular network and key genetic factors during regeneration, the underlying epigenetic landscape remains incompletely understood. Here, we explored methylome and transcriptome dynamics during two-step plant regeneration. During leaf-to-callus transition, genic CG methylation shifts, while pericentromeric regions undergo substantial CG and extensive CHH hypomethylation. more...

(Submitter supplied) The short-term, reversible process that allows plants to cope with immediate environmental fluctuations is often referred to as acclimation. Plant acclimation help maintain the balance of natural systems, supporting biodiversity and the services that ecosystems provide, such as carbon sequestration and water regulation. With climate change modifying the distribution area of plants and causing more frequent and severe weather events, knowledge of how plants acclimate can inform strategies to manage ecosystems and agriculture. more...

(Submitter supplied) Cold stress impedes the growth and development of plants, restricts the geographical distribution of plant species, and impacts crop productivity. In this study, we analyzed the Arabidopsis thali-ana transcriptome to identify genes with differential expression (DEGs) in 14-day-old plantlets exposed to temperatures of 0°C, 4°C, and 10°C for 24 h, compared to the 22°C control group. We found 31 genes shared among three low temperatures, with 9 genes common to 0°C-4°C, 8 genes to 4°C-10°C, and 2 genes to 0°C-10°C among the top 50 cold-induced genes from each tempera-ture. more...

(Submitter supplied) Phytosulfokine (PSK) is a plant peptide hormone that contributes to plant signaling and induced various of effects, including growth, senescence, stress tolerant and defense responses. PSK is a pentapeptide with two tyrosine sulfated by tyrosylprotein sulfotransferase (TPST) enzyme. The sulfated PSK can bind to its cell surface receptors, but the transcriptional readouts remain largely unknown. Here, we treated tpst mutant that are unable to produce native sulfated PSK with synthetic active PSK to capture concentration-sensitive readouts of PSK signaling.
