    Brassinosteroids in plant growth and development
    (Elsevier B.V., 2023) Yadav, Ritesh Kumar; Devi, Loitongbam Lorinda; Singh, Amar Pal
    Brassinosteroids (BRs) are crucial for modulating several plant-related growth activities in the plant. The essential roles of BRs in modulating growth have been well characterized. Recently, BRs emerged as key players, which are accountable for governing stress-mediated responses like high temperature and nutrient deficiency. The genetic components of BRs signaling starting with membrane-confined receptors to the nuclear transcriptional effectors have been characterized. Here, we summarize the advances in the BRs signaling pathway and its spatiotemporal regulation in context with plant growth and development. Further, we highlight the essential role of BRs in regulating the root-and-shoot development, including the effect of BRs on stomata development and physiology as well as in root system architecture modulation. This summarized information will shed light on the current understanding of the BRs regulatory network and its multiple levels of cross talk with the other growth-related hormones in determining the plant performance under stress conditions.

    Nitric oxide: Interaction with auxins, brassinosteroids, and abscisic acid
    (John Wiley & Sons, 2022) Gupta, Shreya; Devi, Loitongbam Lorinda; Singh, Amar Pal
    Studies have identified the central role of nitric oxide in stress mitigation through the modulation of physiological and biochemical pathways including germination, photosynthesis regulation, and programmed cell death. Nitric Oxide in Plants: A Molecule with Dual Roles provides a detailed account of the physio-biochemical, molecular, and omic basis of NO-mediated responses in crop plants under different stresses. Summarizing recent work from leading researchers in the field, this up-to-date volume presents the current understanding of the modulation of the endogenous nitric oxide concentration following exogenous treatments and nitric oxide scavengers or inhibitors. The contributors discuss topics such as NO-mediated regulation of growth, photosynthesis, and tolerance mechanisms, the reductive and oxidative pathways of NO synthesis, molecular interventions for enhancing NO synthesis, the role of nitrogen in production of NO, beneficial microbes in NO production under normal and changing environmental conditions, and more.
