The abstract of the present chapter is embowed with the plant growth regulators along with some unusual types in functioning and modulation of different physiological processes. The secondary metabolites with their sources, chemical configuration, and biosynthesis are the major emphasis in plant physiology as growth substances. The interactions and chemical modifications of those biometabolites have been described in different ecological perspectives and their variations. The metabolomics of such secondary metabolites are the most interesting in variabilities of different functional groups involved in chemical diversity of physiological processes. The tracing of complicated cascades of these substances are described with perception of stress signal, its amplification and modulation for physiological responses. A brief account of phenotyping of the plant types is presented in concise manner for the plant modeling under the normal and stressful condition. The categories of these unconventional growth substances were depicted with photobiological phenomena. The perception of light as signal and their measurement through modern state-of-art may characterize the few compounds to be effective under few environmental variants. The major roles of these compounds in cross road of reactive oxygen species through cellular organelles have revealed some interesting aspects. The highlight of transcriptome analysis for the gene induction by these growth regulators is another module to support the involvement in abiotic stress tolerance.
