Atmospheric stressors include a variety of pollutant gases such as CO2, nitrous oxide (NOx), and sulfurous compounds which could have natural origin or be generated by uncontrolled human activity. Nevertheless, other atmospheric elements including high low temperatures, ozone (O3), UV-B radiation, acid rain among others can affect, at different levels, large number plant species, particularly those agronomic interest. Paradoxically, both nitric (NO) hydrogen sulfide (H2S), until recently were considered toxic since they are part the polluting gases; however, present, these molecules mechanism response to multiple stresses exert signaling functions usually an associated stimulation enzymatic non-enzymatic antioxidant systems. At gasotransmitters essential components defense against wide range environmental ones. This review aims provide updated vision endogenous metabolism NO H2S in cells deepen how exogenous application contribute crop resilience, particularly, stimulating

Background Transposable elements constitute a large portion of plant genomes and, due to their ability change genomic localization, they largely contribute genome evolution and adaptability. Miniature inverted-repeat transposable (MITEs), small size localization near genes, seem be major source potential functional variability. Effects imposed by MITE on the expression associated genes through redistributing cis-regulatory have been postulated, but our knowledge in this area still remains limited. Results We showed that MITEs carrot are enriched with binding sites for LHY/RVE transcription factors. Experimental validation using DcLHY-DAP-seq not only confirmed enrichment DcLHY within MITEs, also demonstrated from DcTourist_15 family likely play key role these factor sites. insertional polymorphisms correspond changes both control conditions response heat stress. In addition placing individual under DcLHY/RVE factors, copies were found promoters involved sulfur metabolism cysteine biosynthesis. The rice OsLHY suggests phenomenon MITE-driven rewiring regulation may more widespread across kingdom. Conclusions Carrot particularly those family, drive genome, especially context stress responsiveness, as possibly fine-tune gene factors family.
