“…The expression analysis of miRNAs in different species during light response showed that the expression patterns differed among species. For instance, miR398 of A. thaliana and longan was up‐regulated under blue light, miR159 was up‐regulated under blue light in Brassica rapa but down‐regulated in longan, while miR167 was down‐regulated under blue light in Arabidopsis but was not expressed in longan. Some miRNAs have also different expression patterns in different species, and we found that miRNAs in the same family can also have different expression patterns.…”

“…In addition to the above regulatory methods, a number of studies have reported important regulatory functions for plant micro RNAs (miRNAs) in controlling gene expression of light response. 14,15 Micro RNAs are endogenous single-stranded RNA molecules, 20-25 nucleotides in length, which lack an open reading frame and the ability to encode proteins. They suppress the expression of transcripts that have near-perfect complementarity via transcript cleavage and/or translational repression.…”

“…Therefore, in addition to blue-light sensing, another mechanism is involved in the determination of palisade cell phenotype in response to white HL conditions. Generally, white HL conditions generated using fluorescent lamps includes light of wavelengths 400-750 nm (L opez-Juez et al, 2007;Pashkovskiy et al, 2016). The canonical functions of blue-light receptors are modified under some light conditions.…”

“…The active form of cryptochromes can be converted into the inactive form by further perception of green light (Bouly et al, 2007). In addition, irradiation with white fluorescent light increases the transcript levels of several genes, including photoreceptors, auxin-response factors, and miR-NAs, compared with the transcript levels under blue light of identical intensity (Pashkovskiy et al, 2016).…”

SummaryPlant morphological and physiological traits exhibit plasticity in response to light intensity. Leaf thickness is enhanced under high light (HL) conditions compared with low light (LL) conditions through increases in both cell number and size in the dorsoventral direction; however, the regulation of such phenotypic plasticity in leaf thickness (namely, sun‐ or shade‐leaf formation) during the developmental process remains largely unclear. By modifying observation techniques for tiny leaf primordia in Arabidopsis thaliana, we analysed sun‐ and shade‐leaf development in a time‐course manner and found that the process of leaf thickening can be divided into early and late phases. In the early phase, anisotropic cell elongation and periclinal cell division on the adaxial side of mesophyll tissue occurred under the HL conditions used, which resulted in the dorsoventral growth of sun leaves. Anisotropic cell elongation in the palisade tissue is triggered by blue‐light irradiation. We discovered that anisotropic cell elongation processes before or after periclinal cell division were differentially regulated independent of or dependent upon signalling through blue‐light receptors. In contrast, during the late phase, isotropic cell expansion associated with the endocycle, which determined the final leaf thickness, occurred irrespective of the light conditions. Sucrose production was high under HL conditions, and we found that sucrose promoted isotropic cell expansion and the endocycle even under LL conditions. Our analyses based on this method of time‐course observation addressed the developmental framework of sun‐ and shade‐leaf formation.

“…Briefly, blue light stimulated the gene expression pattern of photoreceptors, reducing the expression of phytochrome A, phytochrome D, and crytochrome1. This lead to the upregulation of auxin response factors, which reduced the sensitivity of plant cells to auxin (Pashkovskiy et al, 2016). The expression level of CsLHY was significantly higher in the plantlets grown under blue light condition than that of other light treatments (Fig.…”

High yield is one of the core standards of elite tea cultivars. LHY, a key component of the circadian clock, controls various biomass metabolic and developmental processes; and light is a crucial environmental factor that regulates biomass metabolism and modulates plant development and growth. Therefore, in the present study, we evaluated the effect of different light qualities via light-emitting diode (LED) on the morphogenesis and expression of CsLHY by qRT-PCR in in vitro tea plantlets. The findings suggested that the red light had an effect on bud outgrowth, blue light stimulated the content of carotenoids and significantly higher expression level of CsLHY, and far-red light dramatically suppressed the expression of CsLHY and lead to the elongation of internode and small leaf areas. The tentative correlations between the phenotypic responses and expression of CsLHY under different light qualities were discussed, which involved multiple light signaling pathways including phytochrome or cryptochrome, and auxin signaling. Besides the novel discoveries on the connections between light quality and the growth of in vitro tea plantlets, the experimental approach in this study could serve as a practical tool for induced and directed growth of tea plantlets and other in-depth study of gene function upon such light treatment.
