“…Independently from the light quality and kind of photoreceptor involved in light perception, the downstream event proceeds via a complex network of early signalling factors, central integrators, and final effectors. Please refer to some recent reviews [ 37 , 38 , 39 , 40 ] for a detailed summary of the current knowledge of the transcriptional network and mechanisms regulating the response to the different light spectral composition. Interestingly, CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1), which promotes the proteasome-mediates degradation of key factors involved in light signalling, is involved in the response to any light radiation, from UV to far-red wavelengths [ 41 ].…”

Plants continuously rely on light as an energy source and as the driver of many processes in their lifetimes. The ability to perceive different light radiations involves several photoreceptors, which in turn activate complex signalling cascades that ultimately lead to a rearrangement in plant metabolism as an adaptation strategy towards specific light conditions. This review, after a brief summary of the structure and mode of action of the different photoreceptors, introduces the main classes of secondary metabolites and specifically focuses on the influence played by the different wavelengths on the content of these compounds in agricultural plants, because of their recognised roles as nutraceuticals.

“…JAZs modulate interplays of JA and light pathways in growth–defense balance (Ballaré, 2014; Fernández‐Milmanda & Ballaré, 2021; Pierik & Ballaré, 2021). Far‐red light inactivates the phyB receptor to repress JA sensitivity via JAZ10 (Cerrudo et al ., 2012; Cargnel et al ., 2014; Leone et al ., 2014; Cerrudo et al ., 2017).…”

Functional specificity, diversity, and redundancy of Arabidopsis JAZ family repressors in jasmonate and COI1‐regulated growth, development, and defense

In response to jasmonates (JAs), the JA receptor Coronatine Insensitive 1 (COI1) recruits JAzinc-finger inflorescence meristem (ZIM)-domain (JAZ) family repressors for destruction to regulate plant growth, development, and defense. As Arabidopsis encodes 13 JAZ repressors, their functional specificity, diversity, and redundancy in JA/COI1-mediated responses remain unclear.We generated a broad range of jaz mutants based on their phylogenetic relationship to investigate their roles in JA responses. The group I JAZ6 may play an inhibitory role in resistance to Botrytis cinerea, group II (JAZ10)/III (JAZ11/12) in JA-regulated root growth inhibition and susceptibility to Pseudomonas syringae pv tomato DC3000, and group IV JAZ3/4/9 in flowering time delay and defense against insects. JAZs exhibit high redundancy in apical hook curvature.

“…We assume LightCue is a promising tool to study the effect of local spectral cues on plant photomorphogenesis; for example, to decorrelate the effects of R:FR, PPFD and sugars in the hormonal regulatory network. By adapting LightCue to blue or UV wavelengths, it could also be used to unravel the regulatory role of each specific light signal in plant growth, resource acquisition and allocation, but also in plant defense mechanisms [46]. Given the geometry of LightCue, it can be adapted to the spatial conformation of organs of various species (wheat ears, cereal tillers, fruits), the rings can also be enlarged to fit larger organs.…”

Plasticity of plant architecture is a promising lever to increase crop resilience to biotic and abiotic damage. Among the main drivers of its regulation are the spectral signals which occur via photomorphogenesis processes. In particular, branching, one of the yield components, is responsive to photosynthetic photon flux density (PPFD) and to red to far-red ratio (R:FR), both signals whose effects are tricky to decorrelate in the field. Here, we developed a device consisting of far-red light emitting diode (LED) rings. It can reduce the R:FR ratio to 0.14 in the vicinity of an organ without changing the PPFD in outdoor high irradiance fluctuating conditions, which is a breakthrough as LEDs have been mostly used in non-fluctuant controlled conditions at low irradiance over short periods of time. Applied at the base of rapeseed stems during the whole bolting-reproductive phase, LightCue induced an expected significant inhibitory effect on two basal targeted axillary buds and a strong unexpected stimulatory effect on the overall plant aerial architecture. It increased shoot/root ratio while not modifying the carbon balance. LightCue therefore represents a promising device for progress in the understanding of light signal regulation in the field.
