Moreover, Ca is an essential element for plant growth and is receiving increasing attention for its ability to mitigate the negative effects of environmental stress on plants. In the present study, we investigated the effect of Ca on the growth and transcriptome of under salt stress.

Growth and Physiological Responses of Magnoliaceae to NaCl Stress.

The growth and physiological characteristics of four Magnoliaceae plants (, , and two varieties of (Jiaohong 1 and Jiaohong 2)) were investigated. Four Magnoliaceae plants were subjected to various concentrations of NaCl for 60 days: 0 mM, 60 mM, 120 mM, 180 mM, and 240 mM. The leaf water content (LWC), relative growth rate of plant height and stem diameter, photosynthetic pigments, and photosynthetic rate () decreased during the NaCl treatments, indicating slowed growth and photosynthesis.

First Report of Leaf Spot Caused by on in Hubei, China.

belongs to the Magnoliaceae family. Its variation-rich flowers (tepal number from 9 to 46, tepal color from pink to bright red) and excellent wood characteristics (strong, straight, texture) have important ornamental and economic value (Duan et al. 2019; Luyi et al.

Transcriptomic Analysis Reveals the Positive Role of Abscisic Acid in Endodormancy Maintenance of Leaf Buds of .

(Magnoliaceae) is a deciduous landscape species, known for its ornamental value with uniquely shaped and coloured tepals. The species has been introduced to many cities in south China, but low temperatures limit the expansion of this species in cold regions. Bud dormancy is critical for plants to survive in cold environments during the winter.

Physiological and transcriptome analysis of Magnolia denudata leaf buds during long-term cold acclimation.

Background: Magonlia denudata is an important perennial tree species of the Magnoliaceae family, known for its ornamental value, resistance to smoke pollution and wind, role in air purification, and robust cold tolerance. In this study, a high-throughput transcriptome analysis of leaf buds was performed, and gene expression following artificial acclimation 22 °C, 4 °C and 0 °C, was compared by RNA sequencing.

Results: Over 426 million clean reads were produced from three libraries (22 °C, 4 °C and 0 °C).

Conservation and divergence of ancestral AGAMOUS/SEEDSTICK subfamily genes from the basal angiosperm Magnolia wufengensis.

AGAMOUS/SEEDSTICK (AG/STK) subfamily genes play crucial roles in the reproductive development of plants. However, most of our current knowledge of AG/STK subfamily genes is restricted to core eudicots and grasses, and the knowledge of ancestral exon-intron structures, expression patterns, protein-protein interaction patterns and functions of AG/STK subfamily genes remains unclear. To determine these, we isolated AG/STK subfamily genes (MawuAG1, MawuAG2 and MawuSTK) from a woody basal angiosperm Magnolia wufengensis (Magnoliaceae).

De novo transcriptome sequencing and gene expression profiling of Magnolia wufengensis in response to cold stress.

Background: Magnolia wufengensis is a new species of Magnolia L. and has considerable ornamental and economic value due to its unique characteristics. However, because of its characteristic of poor low temperature resistance, M.

Microclimate simulation and model optimization of the effect of roadway green space on atmospheric particulate matter.

Urban green spaces have the potential to mitigate and regulate atmospheric pollution. However, existing studies have primarily focused on the adsorption effect of different plants on atmospheric particulate matter (PM), whereas the effect of green space on PM has not been adequately addressed. In this study, the effect of different urban green space structures and configurations on PM was investigated through the 3D computational fluid dynamics (CFD) model ENVI-met by treating the green space as a whole based on field monitoring, and at the same time, the regulatory effect of green space on PM was examined by integrating information about the forest stand, PM concentration, and meteorological factors.

Gene duplication led to divergence of expression patterns, protein-protein interaction patterns and floral development functions of AGL6-like genes in the basal angiosperm Magnolia wufengensis (Magnoliaceae).

The MADS-box family genes play critical roles in the regulation of growth and development of flowering plants. AGAMOUS-LIKE 6 (AGL6)-like genes are one of the most enigmatic subfamilies of the MADS-box family because of highly variable expression patterns and ambiguous functions, which have long puzzled researchers. A lot of AGL6 homologs have been identified from gymnosperms and angiosperms.

An investigation of the leaf retention capacity, efficiency and mechanism for atmospheric particulate matter of five greening tree species in Beijing, China.

Urban trees have the potential to reduce air pollution, but the retention capacity and efficiency of different tree species for atmospheric particulate matter (PM) accumulation and the underlying mechanism hasn't been well understood. To select tree species with high air purification abilities, the supplementing ultrasonic cleaning (UC) procedure was first introduced into the conventional leaf cleaning methods [single water cleaning (WC) or plus brush cleaning (BC)] for eluting the leaf-retained PM. Further updates to the methodology were applied to investigate the retention capacity, efficiency, and mechanism for PM of five typical greening tree species in Beijing, China.

Various response of Pinus tabulaeformis Carr. regeneration in artifical gaps.

Understanding the influence of gaps in promoting canopy recruitment will help to maintain structural stability and achieve continuous forest cover. We established three control plots and experimental plots with three replications each (gap sizes L-I, L-II, L-III, and L-IV) in a Chinese pine (Pinus tabulaeformis Carr.) plantation to test the short-term effects of gap size on the age distribution, density and growth, and annual height and ground diameter growth for regeneration established before (REBG) and after (REAG) gap creation.

[Dynamic change of Yulania sap flow before dormancy in response to environmental factors].

From September 26 to November 5, 2011, the sap flow of Yulania wufengensis trees including cold-resistance type (HK) and non cold-resistance type (HF), Y. 'Sunspire' (HY), and Yulania x soulangeana (EQ) which were introduced into Beijing four years before was monitored by Flow-32 stem heat balance sensor, and, in combining with the environmental factors monitored synchronically, the changes of the sap flow before dormancy and the environmental factors were analyzed, with the responses of the sap flow to the environmental factors investigated at the scales of 0.5 h and 1 day.
