Emerging connections between small RNAs and phytohormones [PDF]
, 2020 Small RNAs (sRNAs), mainly including miRNAs and siRNAs, are ubiquitous in eukaryotes. sRNAs mostly negatively regulate gene expression via (post-)transcriptional gene silencing through DNA methylation, mRNA cleavage, or translation inhibition.

MethodsX, 2021 Eddy covariance (EC) method has been used to measure CO2 fluxes over various ecosystems. Recently, the EC method has been also deployed in urban areas to measure CO2 fluxes. Urban carbon cycle is complex because of the additional anthropogenic processes unlike natural ecosystems but the EC method only measures the net sum of all CO2 sources and sink ...

A review on heavy metal accumulation and toxicity in biotic and abiotic components
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Pollutants in the environment remains to be a global issue and among the greatest challenges confronting mankind. Among the various kinds of pollutants, heavy metals have drawn a lot of attention owing to their toxicity. Heavy metals are recognized to be naturally existing, however they are introduced in considerable quantities ...
