Plant biostimulants are compounds, living microorganisms, or their constituent parts that alter plant development programs. The impact of biostimulants is manifested in several ways: via morphological, physiological, biochemical, epigenomic, proteomic, and transcriptomic changes. For each of these, a response and alteration occur, and these alterations in turn improve metabolic and adaptive performance in the environment. Many studies have been conducted on the effects of different biotic and abiotic stimulants on plants, including many crop species. However, as far as we know, there are no reviews available that describe the impact of biostimulants for a specific field such as transcriptomics, which is the objective of this review. For the commercial registration process of products for agricultural use, it is necessary to distinguish the specific impact of biostimulants from that of other legal categories of products used in agriculture, such as fertilizers and plant hormones. For the chemical or biological classification of biostimulants, the classification is seen as a complex issue, given the great diversity of compounds and organisms that cause biostimulation. However, with an approach focused on the impact on a particular field such as transcriptomics, it is perhaps possible to obtain a criterion that allows biostimulants to be grouped considering their effects on living systems, as well as the overlap of the impact on metabolism, physiology, and morphology occurring between fertilizers, hormones, and biostimulants.
植物生物刺激素是能够改变植物发育程序的化合物、活的微生物或其组成部分。生物刺激素的影响通过多种方式体现：通过形态学、生理学、生物化学、表观基因组学、蛋白质组学和转录组学的变化。针对其中每一个方面，都会产生响应和改变，并进而改善植物在环境中的代谢和适应能力。关于不同生物和非生物刺激素对植物（包括许多作物品种）的影响，已经开展了许多研究。然而，据我们所知，目前尚无综述描述生物刺激素在转录组学等特定领域的影响，而这正是本综述的目的。对于农业用产品的商业注册流程而言，有必要区分生物刺激素与农业中使用的其他法定产品类别（如肥料和植物激素）的特定影响。对于生物刺激素的化学或生物学分类，鉴于引起生物刺激的化合物和生物体种类繁多，该分类被视为一个复杂的问题。然而，通过专注于转录组学等特定领域影响的方法，或许有可能获得一个标准，从而能够根据生物刺激素对生物系统的影响以及肥料、激素和生物刺激素之间在代谢、生理和形态方面影响的重叠情况，对生物刺激素进行分组。
