Solanum lycopersicum and BC204 RNAseq data

Plant biostimulants have been earmarked as one of the major groups of new plant growth promoting substances to drive a much-needed revolution in agriculture. One such PB, BC204, has been used to great success, but there is no peer-reviewed data to explain the possible mechanisms by which it exerts its effects. In this study, an RNA-seq approach was adopted to elucidate the effects of BC204 on shoot tissues of hydroponically grown Solanum lycopersicum seedlings at the molecular level. BC204, applied via foliar spray at a concentration of 0.05% (v/v), stimulated root and shoot biomass production, root and shoot length, and stem width compared to the untreated control plants. Out of the 33308 transcripts analysed, 18.059% of all genes were significantly differentially expressed between the control and treated groups, of which 8.776% were upregulated and 9.283% downregulated. Most notably, genes involved in signalling, stress and protein metabolism were upregulated, which could explain the observed increases in growth. Additionally, hormone metabolism and genes involved in transcription and other regulation processes were also upregulated. Genes involved in protein metabolism were mostly downregulated.

植物生物刺激剂已被确定为推动农业迫切需要的革命性变革的主要新型植物生长促进物质之一。其中一种植物生物刺激剂，BC204，已被成功应用于实践中，然而，尚无同行评审的数据能够解释其发挥作用的潜在机制。在本研究中，采用RNA测序方法，旨在阐明BC204对水培生长的番茄（Solanum lycopersicum）幼苗茎部组织的分子层面影响。BC204以0.05%（体积比）的浓度通过叶面喷施处理后，与未处理对照组植物相比，刺激了根和茎的生物量生产、根和茎的长度以及茎的宽度。在分析出的33308个转录本中，18.059%的基因在对照组和处理组之间存在显著差异表达，其中8.776%的基因表达上调，9.283%的基因表达下调。值得注意的是，参与信号传导、应答和蛋白质代谢的基因表达上调，这可能解释了观察到的生长增加。此外，激素代谢以及参与转录和其他调控过程的基因也呈现上调。与蛋白质代谢相关的基因大多表达下调。
