Acute NO Stress Shortens the Median Survival Period of 'Elizabeth Angus' by Disrupting Tissue Structure and Photosynthetic Response Centers.

The air pollutant NO is one of the major constraints on plant growth, and the ecological value of the ornamental plant can be weakened by NO. In this study, an indoor 4 μL·L NO simulated fumigation test was conducted with three treatments, CK (normal growth with clean air), T1 (4 μL·L NO + 8 h/d), and T2 (4 μL·L NO + 24 h/d), which were set up with considerations for time and concentration. The results demonstrated that most of the morphological parameters of 'Elizabeth Angus', except for the floral organs, were decreased in the root, stem, leaf, and bract.

Combined Transcriptome and Proteome Analysis Provides Insights into Petaloidy in Pomegranate.

Petaloidy leads to a plump floral pattern and increases the landscape value of ornamental pomegranates; however, research on the mechanism of petaloidy in ornamental pomegranates is limited. In this study, we aimed to screen candidate genes related to petaloidy. We performed transcriptomic and proteomic sequencing of the stamens and petals of single-petal and double-petal flowers of ornamental pomegranates.

Effect of different plant communities on NO in an urban road greenbelt in Nanjing, China.

As an important part of urban ecosystems, plants can reduce NO concentrations in the air. However, there is little evidence of the effects of different plant communities on NO concentrations in street-scale green spaces. We used a multifunctional lifting environmental detector to investigate the impact of environmental factors and small plant communities on NO concentrations in street green spaces during the summer and winter in Nanjing, China.

Establishing an Efficient Regeneration System for Tissue Culture in 'Miss Manila'.

plants have important ornamental and cultural value, as well as applications, for example, in improving the ecological environment, sterilization and as anti-virals in medicines, etc. Among many varieties, 'Miss Manila' is more popular in landscape applications in southern China because of its excellent qualities. However, because of the difficulty of sexual reproduction, low rooting rate of asexual propagation cuttings and low temperature tolerance, its large-scale development is limited.
