“…Another Ca 2+ sensor protein, CML42, does not affect the herbivore-induced and the wound-induced JA, JA-Ile and OPDA elevations [25]. A study of JA content in rice roots showed that OsCBL1 is a positive regulator of JA biosynthesis, as the JA content in OsCBL1-knockdown plants was decreased compared to the wild-type plants [63].…”

Plants are constantly exposed to environmental stresses. Local stimuli sensed by one part of a plant are translated into long-distance signals that can influence the activities in distant tissues. Changes in levels of phytohormones in distant parts of the plant occur in response to various local stimuli. The regulation of hormone levels can be mediated by long-distance electrical signals, which are also induced by local stimulation. We consider the crosstalk between electrical signals and phytohormones and identify interaction points, as well as provide insights into the integration nodes that involve changes in pH, Ca2+ and ROS levels. This review also provides an overview of our current knowledge of how electrical signals and hormones work together to induce a systemic response.

“…Our previous study showed that decreasing the expression of OsCBL1 (i.e., OsCBL1 -KD) inhibited the growth of rice roots under 1/2-strength Murashige and Skoog (MS) medium growth conditions [15]. Root growth is inextricably linked to nutrient elements.…”

“…Experiments were performed with wild-type (WT) rice (ShijinB) and transgenic OsCBL1 -knockdown ( OsCBL1 -KD) plants reported in our previous study [15]. Seeds of the WT and knockdown plants were surface sterilized with 5% (v/v) NaClO at room temperature for 30 min and then rinsed with double-distilled water.…”

Nitrate signaling integrates and coordinates gene expression and plant growth; however, the underlying molecular mechanisms involved remain poorly understood. Our previous study revealed that rice calcineurin B-like protein 1 (OsCBL1) modulates lateral root elongation by affecting auxin biosynthesis. Here, we report that OsCBL1 also modulates nitrate signaling to regulate rice seedlings growth. Compared with wild-type seedlings, seedlings of OsCBL1-knockdown (OsCBL1-KD) plants showed a suppressed growth phenotype, which included reduced root and shoot fresh weights and shorter radicles, crown roots, and lateral roots, when grown in nitrogen-free conditions. Although the growth defects of OsCBL1-KD plants could be partially rescued by the addition of nitrate to the growth conditions, the nitrate uptake capability of the OsCBL1-KD plants did not differ from that of wild-type plants as assessed via nitrate content and 15NO3− influx experiments. The nitrate-regulated expression of nitrate signal sentinel genes (OsNRT2.1 and OsNRT2.2) was affected in the OsCBL1-KD plants under both long- and short-term nitrate treatments. Overall, our results showed a novel role for OsCBL1 in the regulation of nitrate signaling and nitrate-mediated rice growth.

“…AtCIPK6 significantly affects LR formation by positively regulating root basipetal and shoot-to-root auxin transport 73 . OsCBL1 is required for LR development in rice by mediation of auxin biosynthesis 17 . In line with previous studies, a multitude of Ca 2+ -signaling-related genes, including CML6 , CML45 , CML50 , CIPK6 , CDPK10 , and CDPK33 , as well as PBP1 , were significantly up-regulated in the roots of CmANR1 -overexpressing chrysanthemum compared to WT plants (Figs.…”

“…Natural auxins (e.g., indole-3-acetic acid (IAA)) and synthetic analogs (e.g., indole-3-butyric acid (IBA)) have a powerful and stimulatory effect on rooting in many plant species 12 , 14 , 15 . A diverse range of studies have shown that auxin is central to AR and LR development in plants, where it cross-talks with other signals (e.g., calcium signal) 16 , 17 , regulatory genes (e.g., AtMYB93 , SHR , and ERF3 ) 18 – 20 , or phytohormones (e.g., ethylene and gibberellins) 21 – 23 . Furthermore, auxin-related biological processes, such as signal transduction, polar transport, and local biosynthesis, account for the primary underlying molecular mechanisms regulating AR or LR formation 10 , 11 , 24 – 27 .…”

Plant root systems are essential for many physiological processes, including water and nutrient absorption. MADS-box transcription factor (TF) genes have been characterized as the important regulators of root development in plants; however, the underlying mechanism is largely unknown, including chrysanthemum. Here, it was found that the overexpression of CmANR1, a chrysanthemum MADS-box TF gene, promoted both adventitious root (AR) and lateral root (LR) development in chrysanthemum. Whole transcriptome sequencing analysis revealed a series of differentially expressed unigenes (DEGs) in the roots of CmANR1-transgenic chrysanthemum plants compared to wild-type plants. Functional annotation of these DEGs by alignment with Gene Ontology (GO) terms and biochemical pathway Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis indicated that CmANR1 TF exhibited “DNA binding” and “catalytic” activity, as well as participated in “phytohormone signal transduction”. Both chromatin immunoprecipitation–polymerase chain reaction (ChIP-PCR) and gel electrophoresis mobility shift assays (EMSA) indicated the direct binding of CmPIN2 to the recognition site CArG-box motif by CmANR1. Finally, a firefly luciferase imaging assay demonstrated the transcriptional activation of CmPIN2 by CmANR1 in vivo. Overall, our results provide novel insights into the mechanisms of MADS-box TF CmANR1 modulation of both AR and LR development, which occurs by directly regulating auxin transport gene CmPIN2 in chrysanthemum.
