Links between the pandemic and urban green spaces, a perspective on spatial indices of landscape garden cities in China.

The COVID-19 pandemic has inevitably changed people's lifestyles and demands for urban green space and public open space. The National Landscape Garden Cities in China (NLGCC) policy is one of the key development models in China aimed at building sustainable cities and society. In this paper, the development of the study's selection criteria and the significance and benefits of the NLGCC policy are first summarised.

Genome-Wide Identification and Low-Temperature Expression Analysis of bHLH Genes in .

is an illustrious ornamental woody plant with colorful flowers, delicate fragrances, and graceful tree forms. Low temperature limits its geographical distribution. The basic helix-loop-helix (bHLH) proteins exist in most eukaryotes as a transcription factor superfamily, which play a crucial role in metabolism, physiology, development, and response to various stresses of higher organisms.

Metabolic, Enzymatic Activity, and Transcriptomic Analysis Reveals the Mechanism Underlying the Lack of Characteristic Floral Scent in Apricot Mei Varieties.

Apricot mei, a hybrid of and , usually has greater cold resistance than ; however, most varieties of Apricot mei lack the characteristic floral scent of . The volatile and intracellular metabolites, activity levels of key enzymes, and transcriptomes of blooming flowers were comprehensively investigated in five varieties of . Benzyl acetate and eugenol were determined to be the main components of the floral scent.

Screening of optimal reference genes for qRT-PCR and preliminary exploration of cold resistance mechanisms in Prunus mume and Prunus sibirica varieties.

Prunus sibirica and Prunus mume are closely related plant species that differ in cold tolerance. Hybrids of P. sibirica and true mume, belonging to the apricot mei group, inherited strong cold resistance from P.

A Comparative Analysis of Floral Scent Compounds in Intraspecific Cultivars of with Different Corolla Colours.

is the only fragrant flowering species of . According to the previous studies, benzyl acetate and eugenol dominate its floral scent. However, the diversity of its floral scents remains to be elucidated.

Genome-Wide Analysis of Members of the WRKY Gene Family and Their Cold Stress Response in Prunus mume.

Prunus mume, which is a rosaceous arbor with very high ornamental, edible and medical values, has a distribution that is mainly restricted by low temperature. WRKY transcription factor genes play crucial roles in the growth, development, and stress responses of plants. However, the WRKY gene family has not been characterised in P.

Genome-wide identification, characterization, expression and enzyme activity analysis of coniferyl alcohol acetyltransferase genes involved in eugenol biosynthesis in Prunus mume.

Prunus mume, a traditional Chinese flower, is the only species of Prunus known to produce a strong floral fragrance, of which eugenol is one of the principal components. To explore the molecular mechanism of eugenol biosynthesis in P. mume, patterns of dynamic, spatial and temporal variation in eugenol were analysed using GC-MS.

Expansion of genes in the genome induces characteristic floral scent production.

is the only plant in the genus of the Rosaceae family with a characteristic floral scent, and the main component of this scent is benzyl acetate. By contrast, benzyl acetate is not synthesized in flowers. Here, we searched for () genes based on genomic data from and and found 44 unique in .
