“…In addition, MEcPP-mediated induction of phyB abundance under the red light condition, accompanied by reduced auxin and ethylene concentrations, identifies MEcPP as the upstream signal coordinating light and hormonal signaling cascades and uncovers functional hierarchy of these growth regulatory inputs poised to reprogram plant growth in response to the light environment (Jiang et al, 2020) (Fig. 2).…”

The transition from an engulfed autonomous unicellular photosynthetic bacterium to a semiautonomous endosymbiont plastid was accompanied by the transfer of genetic material from the endosymbiont to the nuclear genome of the host, followed by the establishment of plastid-to-nucleus (retrograde) signaling. The retrograde coordinated activities of the two subcellular genomes ensure chloroplast biogenesis and function as the photosynthetic hub and sensing and signaling center that tailors growth-regulating and adaptive processes. This review specifically focuses on the current knowledge of selected stress-induced retrograde signals, genomes uncoupled 1 (GUN1), methylerythritol cyclodiphosphate (MEcPP), apocarotenoid and b-cyclocitral, and 3 0-phosphoadenosine 5 0-phosphate (PAP), which evolved to establish the photoautotrophic lifestyle and are instrumental in the integration of light and hormonal signaling networks to ultimately fashion adaptive responses in an ever-changing environment.

Understanding how cell organelles and compartments communicate with each other has always been an important field of knowledge widely explored by many researchers. However, despite years of investigations, one point—and perhaps the only point that many agree on—is that our knowledge about cellular-signaling pathways still requires expanding. Chloroplasts and mitochondria (because of their primary functions in energy conversion) are important cellular sensors of environmental fluctuations and feedback they provide back to the nucleus is important for acclimatory responses. Under stressful conditions, it is important to manage cellular resources more efficiently in order to maintain a proper balance between development, growth and stress responses. For example, it can be achieved through regulation of nuclear and organellar gene expression. If plants are unable to adapt to stressful conditions, they will be unable to efficiently produce energy for growth and development—and ultimately die. In this review, we show the importance of retrograde signaling in stress responses, including the induction of cell death and in organelle biogenesis. The complexity of these pathways demonstrates how challenging it is to expand the existing knowledge. However, understanding this sophisticated communication may be important to develop new strategies of how to improve adaptability of plants in rapidly changing environments.

“…Calcium constitutes a key element for chloroplast response, and both abiotic and biotic stresses including chitin, flg22, cold, and NaCl induce a Ca 2+ rise in the stroma ( Stael, 2019 ; Teardo et al, 2019 ; Navazio et al, 2020 ). Numerous other signal transducers have been proposed including the calcium-sensing (CaS) protein, mitogen-activated protein kinase (MAPK) cascades, ROS, tetrapyrroles, intermediate products of the isoprenoid biosynthesis, and carotenoid derivatives ( Leister, 2017 ; Teardo et al, 2019 ; Wu et al, 2019 ; Jiang et al, 2020 ; Wang et al, 2020a ). Finally, this retrograde signaling modulates the expression of (a)biotic stress- and photosynthesis-related genes to adapt the photosynthetic machinery ( Wang et al, 2020b ).…”

Chloroplast Electron Chain, ROS Production, and Redox Homeostasis Are Modulated by COS-OGA Elicitation in Tomato (Solanum lycopersicum) Leaves

et al. 2020

The stimulation of plant innate immunity by elicitors is an emerging technique in agriculture that contributes more and more to residue-free crop protection. Here, we used RNA-sequencing to study gene transcription in tomato leaves treated three times with the chitooligosaccharides–oligogalacturonides (COS-OGA) elicitor FytoSave® that induces plants to fend off against biotrophic pathogens. Results showed a clear upregulation of sequences that code for chloroplast proteins of the electron transport chain, especially Photosystem I (PSI) and ferredoxin. Concomitantly, stomatal conductance decreased by half, reduced nicotinamide adenine dinucleotide phosphate [NAD(P)H] content and reactive oxygen species production doubled, but fresh and dry weights were unaffected. Chlorophyll, β-carotene, violaxanthin, and neoxanthin contents decreased consistently upon repeated elicitations. Fluorescence measurements indicated a transient decrease of the effective PSII quantum yield and a non-photochemical quenching increase but only after the first spraying. Taken together, this suggests that plant defense induction by COS-OGA induces a long-term acclimation mechanism and increases the role of the electron transport chain of the chloroplast to supply electrons needed to mount defenses targeted to the apoplast without compromising biomass accumulation.
