QING Huang and colleagues at the institute have found that low-temperature plasma can stimulate the growth of Haematococcus pluvialis and astaxanthin accumulation. Transcriptomics analysis revealed that low-temperature plasma can regulate the synthesis, metabolism, and transport of hormones such as indole-3-acid (IAA), zeatin, and gibberellin (GA) through oxidative stress mechanisms, leading to enhanced growth and higher production of astaxanthin
