“…These authors showed that PYL8 and PYL9 negatively regulate PIF4-mediated trans-activation of ABI5 . Liang et al (2020) analyzed the DNA-binding sites for PIF3 and showed that several ABA signaling genes were found to be potential targets, such as PYL3 , PYL6 , PYL12 , SnRK2.2 , ABI5, and ABF3 ( Table 1 ).…”

It is generally accepted that plants use the complex signaling system regulated by light and abscisic acid (ABA) signaling components to optimize growth and development in different situations. The role of ABA–light interactions is evident in the coupling of stress defense reactions with seed germination and root development, maintaining of stem cell identity and stem cell specification, stem elongation and leaf development, flowering and fruit formation, senescence, and shade avoidance. All these processes are regulated jointly by the ABA–light signaling system. Although a lot of work has been devoted to ABA–light signal interactions, there is still no systematic description of central signaling components and protein modules, which jointly regulate plant development. New data have emerged to promote understanding of how ABA and light signals are integrated at the molecular level, representing an extensively growing area of research. This work is intended to fill existing gaps by using literature data combined with bioinformatics analysis.

“…Activation of ABI5 by PIF1 and their co‐operative action on the downstream target genes indicate the existence of a feed‐forward mechanism. This might not be an exclusive mechanism for PIF1, as PIF3 and PIF5 also bind to the G‐box (CACGTG) on which ABI5 is known to bind (Kim et al ., 2016; Liang et al ., 2020). However, the physical interaction between ABI5 and other PIFs is yet to be investigated.…”

“…However, the physical interaction between ABI5 and other PIFs is yet to be investigated. The direct binding targets of PIF3 and PIF5 include the ABA receptor genes PYL3 , PYL6 and PYL12 (Liang et al ., 2020). Interestingly, PYL8 and PYL9 have been found to physically interact with PIFs, modulating their stability and activity (Qi et al ., 2020).…”

Abscisic acid (ABA) plays a crucial role in plant development, regulating germination, seedling development and stomatal movements, especially under adverse conditions. Light interacts with the ABA signalling pathway to fine tune these processes. Here, we provide an overview of the recent investigations on ABA-light interplay during early plant development after germination. We discuss the multilayered and reciprocal interactions between ABA signalling components and several light signalling modulators, including photoreceptors, transcription factors and posttranslational modifiers. ABSCISIC ACID INSENSITIVE5 acts as a central convergence point for these interactions during postgermination seedling development. ABA also regulates the adaptation of seedlings to challenging light environments. Furthermore, we enlist the role of ABA-light cross-talk in regulating seedling establishment in crops and highlight open questions for future investigations.

“…Currently, it is known that light can modify the growth and morphogenesis through the rearrangement of the hormonal complex, a mechanism of influence on the source-sink system (Kutschera, Briggs, 2003;Wu, 2014;de Wit, Pierik, 2016). The initial stages of photomorphogenesis are accompanied by considerable metabolic changes, phytochrome modification of the hormonal status of seedlings, in particular, the phytohormone transport and formation of gibberellin gradients in plants, and the intensity of natural inhibitors (Dong et al, 2014;Liang et al, 2020). Changes in light undergo ethylene biosynthesis in tissues, contributing to the final morphogenesis and physiological development (Dong et al, 2014;Ahammed et al, 2020).…”

Functional changes in the source-sink system of maize sprouts under combination of external (light/dark) and hormonal (gibberellic acid/retardant) factors during germination were studied. It was found that the phytohormone action significantly increased the coleoptile, root and seedling length, dry matter mass of organs, both in light and in dark. Tebuconazole caused the opposite effect due to its retardant action. The inactivation of endogenous phytohormone was confirmed by less intensive use of seed substances, the minimum dry matter of root and coleoptile and lower reserve utilization rates under tebuconazole influence, in particular under photomorphogenesis condition. The non-maximum mass of cotyledons may indicate a kind of optimization of use of reserves under tebuconazole treatment. Gibberellin stimulated starch breakdown in both light and dark, but starch usage was higher in dark. The lower content of sugar in the seeds of skotomorphic plants in control and under gibberellin action was explained by intense outflow for the organogenesis needs. Gibberellin stimulated the hydrolysis of reserve protein after intensive starch hydrolysis in dark. Specific gibberellin regulation of phosphorus outflow for the organogenesis processes under the photo- and skotomorphogenesis conditions and no regulation for potassium under photomorphogenesis conditions were found.
