“…Our results were agreed with previous findings. In cryptochromes genes, CRY1 and CRY2 were both reported can promote flowering, our results were much the same between other groups 16 . GI and CO are regulated circadian clock, CO was considered as a gene that accelerates flowering in response to long days.…”

Angelica sinensis (Oliv.) Diels is a widely used medicinal plant mainly originated in Gansu, China. Angelica sinensis is greatly demanded in the clinical practice of Chinese medicine due to its broad pharmacological activities of hematopoietic and anti-inflammatory properties. But, the percentage of early flowering in Angelica sinensis arrives to 20%~30%, which severely affects its quality and quantity. Here, transcriptome profiling and digital gene expression analysis were applied to study the mechanism of early flowering in Angelica sinensis . A total of 49,183,534 clean reads were obtained and assembled into 68,262 unigenes, and 49,477 unigenes (72.5%) could be annotated to a minimum of one database in the Nr, Nt, Swiss-Pro, GO, COG and KEGG. Taking the above transcriptome data as a reference, digital gene expression result showed that 5,094 genes expression level were significant changed during early flowering. These annotated genes offered much information promoting that the biosynthesis of secondary metabolites pathway, the hormone signal transduction pathway, and the transcription regulation system may be closely related to the early flowering phenomenon of Angelica sinensis . Further expression patterns of key genes contribute to early flowering were analyzed using quantitative real-time PCR. The transcriptome result offered important gene expression information about early flowering in Angelica sinensis .

“…The photoreceptors govern the metabolite (both primary and secondary) biosynthesis in plants [ 19 , 20 ]. Photoreceptors are important regulators of chlorophyll abundance [ 19 , 240 - 245 ], photosynthesis-related genes [ 19 ], and photosynthetic capacity by directly affecting the proteins involved in the Calvin cycle and electron transport [ 246 ]. Supporting the hypothesis that photoreceptors regulate photosynthesis, there are reports on a reduction in CO 2 uptake in photoreceptor mutants [ 245 , 247 , 248 ].…”

: Changes in environmental conditions like temperature and light critically influence crop production. To deal with these changes, plants possess various photoreceptors such as Phototropin (PHOT), Phytochrome (PHY), Cryptochrome (CRY), and UVR8 that work synergistically as a sensor and stress sensing receptor to different external cues. PHOTs are capable of regulating several functions like growth and development, chloroplast re-location, thermomorphogenesis, metabolite accumulation, stomatal opening, and phototropism in plants. PHOT plays a pivotal role in overcoming the damage caused by excess light and other environmental stresses (heat, cold, and salinity) and biotic stress. The crosstalk between photoreceptors and phytohormones contrib-utes to plant growth, seed germination, photo-protection, flowering, phototropism, and stomatal opening. Molecular genetic studies using gene targeting and synthetic biology approaches have revealed the potential role of different photoreceptor genes in the manipulation of various beneficial agronomic traits. Overexpression of PHOT2 in Fragaria ananassa leads to the increase in anthocyanin content in its leaves and fruits. Artificial illumination with blue light alone and in combination with red light influence the growth, yield, and secondary metabolite production in many plants while in algal species it affects growth, chlorophyll content, lipid produc-tion, and increase its bioremediation efficiency. Artificial illumination alters the morphological, developmental, and physiological characteristics of agronomic crops and algal species. This review focuses on PHOT modulat-ed signalosome and artificial illumination-based photo-biotechnological approaches for the development of Climate-Smart Crops.

“…SAR). A recent study analyzed the contribution of phys and crys to the regulation of proteins involved in chloroplast metabolism and the Calvin cycle, including Rubisco and Rubisco activase (Fox et al, 2015). First, the quadruple phyA;phyB;cry1;cry2 mutant was shown to have reduced chlorophyll levels, harvesting complex, and Calvin cycle proteins.…”
