In order to improve the leaf color and optimize the facility of cultivation system of Aglaonema commutatum ‘Big apple', its hydroponic seedlings were used as the test material in this study, six light qualities(white light, R:B = 1:1, R:B = 1:2, R:B = 2:1, R:B = 1:3, R:B = 3:1, in which R and B represent red light and blue light, respectively)and two photoperiods(8 h·d-1, 12 h·d-1)were cross cultured to determine the growth amount, biomass, soil and plant analyzer development(SPAD)value, anthocyanin content and leaf color parameters(hue value a*, hue value b*, luminosity L* and hue angle h*), and to investigate its response to red and blue light qualities and photoperiodic interactions. The results were as follows:(1)The dry weight and fresh weight of A. commutatum seedlings treated with LP11(R:B=1:3×12 h·d-1)were the highest, which was most conducive to plant growth and biomass accumulation; followed by LP5(R:B=1:3×8 h·d-1)treatment.(2)Under the same light quality condition, the SPAD value of 8 h·d-1 photoperiod was higher than that of 12 h·d-1 photoperiod, the anthocyanin content of 12 h·d-1 photoperiod was higher than that of 8 h·d-1 photoperiod, the SPAD value of LP11 treatment was the lowest and the anthocyanin content was the highest. The leaf color parameters a* and b* of A. commutatum cultured in 12 h·d-1 photoperiod were higher than those in 8 h·d-1 photoperiod, and the value of h* was lower than that in 8 h·d-1 photoperiod.(3)The principal component analysis showed that the LP11 treatment was the most effective in promoting the growth and leaf color improvement of A. commutatum. In conclusion, 12 h·d-1 photoperiod is more conducive to the growth and leaf color change of A. commutatum, and LP11 treatment is the best combination of light quality and photoperiod.

In order to find long non-coding KM As (IncKNAs) related to Paulownia witches' broom (PaWB) and explore its regulation mode, the high-throughput sequencing technology Illumina Hiseq 2<00) was employed to identify IncKNAs in Paulownia tomentosa plantlets ( PT), phytoplasma-infected Paulownia tomentosa plantlets ( PTI), and KM) mg • L~ rifampin-treated phytoplasma-infected Paulownia tomentosa plantlets ( PTIK-100). The results showed that 3 237 candidate IncKNAs were identified. PT/PTI, Pr/PI'IL-lOO, and PTI/PTII.-UX) had 147 of the same IncRNAs in differentially expressed IncKNAs, and their target genes were enriched in 40 GO terms and 119 metabolic pathways. By comparative analysis, 72 IncKNAs may be related to PaWB, and their candidate target genes were mainly enriched in the phospholipase) signaling. Wnt signaling, ABC transport, glycosylphosphat idyl inositol ( GP1) -anchor biosynthesis, secondary metabolite biosynthesis, uhiquitin-mediated proteolysis, and zeatin biosynthesis pathways, as well as glycine, serine, and threonine metabolism. The target genes of IncKNA (TC0NS roles in the interaction between Paulownia and phytoplasma and the cell cycle changes in Paulownia morphogenesis, which lays the foundation for us to understand the mechanism of Paulownia witches' broom occurrence.
