“…In this study, the candidate PpBBX24 associated with the red characteristic of "Zaosu Red" is a B-box protein and belongs to a class of zinc finger transcription factors that contain one or more B-box domains at the N-terminus involved in mediating protein-protein interactions, of which 32 members have been identified in Arabidopsis 31,32 . It has been verified that several plant BBXs play important regulatory roles in photomorphogenesis and anthocyanin accumulation, among which AtBBX20 33 , MdBBX20 34 , AtBBX21 35,36 , PpBBX16 6 , PpBBX18 25 , OsBBX14 37,38 , and MdBBX22 39,40 act as positive regulators, whereas AtBBX19 41 , PpBBX21 23 , AtBBX32 42 , MdBBX37 43 , MdCOL4 (BBX24) 44 , AtBBX24 45 , and AtBBX25 35,46 act as negative regulators.…”

“…In apple, MdCOL4 interacts with MdHY5 via the B-box2 domain of MdCOL4 and the bZIP domain of MdHY5 to synergistically inhibit the expression of MdMYB1. MdCOL4 also directly binds to the three G-box motifs in the promoters of MdANS and MdUFGT to suppress their expression 44 . AtBBX24 attenuates UV-B-induced HY5 accumulation and suppresses its transcriptional activation activity 45 , which is similar to that which occurs for MdCOL4.…”

Red skin is an important quality trait for pear fruits and is determined by the concentration and composition of anthocyanins. The regulatory mechanism underlying anthocyanin accumulation is a popular topic in fruit research. Red mutants are ideal materials for studying the molecular mechanism of color diversity in pear. Although several red pear mutants have been cultivated and are in production, no exact locus containing the responsible genetic mutation has been identified. In this study, by combining the bulked segregant analysis with whole-genome sequencing, we identified a 14 nucleotide deletion mutation in the coding region of the PpBBX24 gene from the red pear mutant "Zaosu Red". We further verified that the deletion was present only in the red mutant of "Zaosu" and in its red offspring, which was different from that which occurred in other red pear fruits. This deletion results in a coding frame shift such that there is an early termination of the PpBBX24 gene and loss of key NLS and VP domains from PpBBX24. The lost domains may reduce or alter the normal function of PpBBX24. In addition, we found that the transcript levels of the PpMYB10 and PpHY5 genes in red samples were significantly higher than those in green samples, whereas the results for the normal-type PpBBX24 gene were the opposite. We ultimately revealed that the 14 nucleotide deletion mutation in the coding region of the PpBBX24 gene is associated with the red skin of the "Zaosu Red" pear. This finding of somatic mutational events will be helpful for breeding new red pear cultivars and for understanding the regulatory mechanisms involved in pear skin pigmentation.

“…Moreover, ultraviolet‐B (UV‐B) light, when perceived by the photoreceptor UVR8, strongly attenuates thermomorphogenesis (20–28°C) via multiple mechanisms that inhibit PIF4 activity (Hayes et al 2017). Moreover, UV‐B and temperature signals were integrated in apple to control fruit coloration through transcription factors MdCOL4 and MdCOL11, which were involved in MdHY5‐mediated signal transduction (Bai et al 2014; Fang et al 2019). These studies indicate the complex, molecularly‐underpinned interaction of light and temperature induced responses in plants (Figure ).…”

“…In addition, two central regulators of photomorphogenesis, HY5 and COP1, are important factors in the integration of light and low temperature signals in plants (Catalá et al 2011; Bai et al 2014; Perea‐Resa et al 2017; Wang et al 2018; Fang et al 2019). Interestingly, HY5 levels are transcriptionally regulated by low temperature, while HY5 mediates the induction of approximately 10% of all Arabidopsis cold‐inducible genes, acting as a positive regulator of cold acclimation (Catalá et al 2011).…”

Rice (Oryza sativa L.) is a major staple food crop for over half of the world's population. As a crop species originated from the subtropics, rice production is hampered by chilling stress. The genetic mechanisms of rice responses to chilling stress have attracted much attention, focusing on chilling-related gene mining and functional analyses. Plants have evolved sophisticated regulatory systems to respond to chilling stress in coordination with light signaling pathway and internal circadian clock. However, in rice, information about light-signaling pathways and circadian clock regulation and their roles in chilling tolerance remains elusive. Further investigation into the regulatory network of chilling tolerance in rice is needed, as knowledge of the interaction between temperature, light, and circadian clock dynamics is limited. Here, based on phenotypic analysis of transgenic and mutant rice lines, we delineate the relevant genes with important regulatory roles in chilling tolerance. In addition, we discuss the potential coordination mechanism among temperature, light, and circadian clock in regulating chilling response and tolerance of rice, and provide perspectives for the ongoing chilling signaling network research in rice.

Roles of non‐visible light and temperature in the regulation of anthocyanin synthesis in fruits and vegetables

The depletion of the ozone layer creates a gate for non‐visible spectra to impact the Earth's surface and interfere with fruit and vegetable growth and developments by affecting their morphology and physiology. The potential contribution of visible light to photosynthetic activity has received significant attention, particularly blue and red/far‐red light in the visible spectrum. However, plants are also inevitably exposed to relatively high doses of non‐visible spectra, including ultraviolet (UV) and infrared (IR) radiation. This review examines the literature on the impact of such non‐visible spectra on fruit and vegetable growth and development. The accumulation of radiation‐absorbing compounds is a primary mechanism of acclimation to changing radiation levels. Anthocyanins are compounds that exhibit high sensitivity to UV and IR radiation as well as temperature variations, playing a crucial protective role against detrimental radiation in plants. Current research helps to elucidate the involvement of low and high temperatures in the control of UVB‐induced anthocyanin accumulation. Different UV radiation types have been shown to affect fruit and vegetable growth and pigment content differentially. Recent studies have also revealed that IR radiation increases anthocyanin content. Furthermore, specific non‐visible spectra mitigate the inhibitory effect of high and low temperature stress on anthocyanin accumulation in fruits and vegetables. These findings have important implications for the horticultural industry, as they suggest that the application of specific of non‐visible light spectra could be a promising approach to increasing the nutritional value and marketability of fruits and vegetables.
