The shoot apical meristem culture has been used widely to produce virus-free plantlets which have the advantages of strong disease resistance, high yield, and prosperous growth potential. However, this virus-free plant will be naturally reinfected in the field. The physiological and metabolic responses in the reinfected plant are still unknown.

Article Synopsis
  • The herbal plant (Thunb. ex A. Murray), known as baiji, has garnered scientific interest for its medicinal properties, especially after a recent outbreak noted in Hangzhou, China, in May 2023.
  • Approximately 60% of baiji plants exhibited blight symptoms, such as brown spots on leaves and stems, leading to wilting, yellowing, and ultimately defoliation and plant death, which negatively impacts herb yield and quality.
  • To isolate the pathogen causing this blight, researchers conducted careful surface disinfection of symptomatic tissues followed by incubation, obtaining eight fungal isolates, whose morphological characteristics were analyzed and confirmed through genomic DNA extraction and phylogenetic analysis.

Article Synopsis
  • The paper discusses a disease affecting traditional Chinese medicine plants that appeared in 2021 in Yueqing city, China, analyzing 127 plant isolates grouped into 13 morphological categories.
  • Researchers identified three main pathogenic strains responsible for the disease, with percentages indicating their prevalence: 71.6% for one strain, 21.3% for another, and 7.1% for the third.
  • To combat the disease, three fungicides were tested for effectiveness, with Meitian showing the strongest results, and it was found to effectively control the bud blight in pot trials.

Winterberry holly () is an economically valuable landscaping ornamental plant. Serious outbreaks have been reported, in its leaf tips curl upward, irregular black brown spots appear on leaves, and extensive defoliation is commonly observed. The incidence in Hangzhou was estimated at 50% and resulted in large economic losses for growers in 2018.

Freezing damage is a common phenomenon responsible for reduced yields of economic crops. Regulation of lipid metabolism plays an important role in plant growth and adaptation during freezing. We previously carried out transcriptome and untargeted metabolome analyses to determine the regulation of flavonol and anthocyanin biosynthesis during freezing treatment (FT) and post-freezing recovery (FR) in Dendrobium catenatum.

Strawberry (Fragaria × ananassa) is an economically important crop in Zhejiang, China. In the autumn of 2021, crown necrobiosis and angular leaf spot was observed in commercial strawberry fields (cultivar 'fenyu') in Cixi, Ningbo, Zhejiang, China (N30°9'55″, E121°21'13″). The disease incidence ranged from 5 to 8 % in the field, but could reach 50 to 60 % in some heavily affected plastic tunnels.

Almost all plants in their natural environment are commonly infected by viruses. These viral infections can cause devastating diseases and result in severe yield and economic losses, making viral diseases an important limiting factor for agricultural production and sustainable development. However, these losses can be effectively reduced through the productions and applications of virus-free plantlets.

Ganoderma lucidum exhibits pronounced anti-inflammatory effects, polysaccharides and triterpenoids are regarded as major constituents displaying the anti-inflammatory activities, whether sterols contribute to this activity remains unclear. Herein Ganoderma lucidum sterols (GLS) were innovatively isolated by a single-step procedure, the profile of GLS was characterized by HPLC-ELSD and shown similar to that of sterols separated by a traditional method, but much higher in content. Furthermore, GLS inhibited inflammation in macrophages by significantly attenuating LPS-induced cell polarization as well as releases and mRNA expressions of pro-inflammatory mediators NO, TNF-α, IL-1β and IL-6.

We performed an integrated analysis of the transcriptome and metabolome from purple (Pr) and normal cultivated varieties (CK) of Dendrobium officinale to gain insights into the regulatory networks associated with phenylpropanoid metabolism and to identify the key regulatory genes of pigmentation. Metabolite and transcript profiling were conducted by ultra-performance liquid chromatography electrospray tandem mass spectrometry (UPLC-ESI-MS/MS) and RNA sequencing. Pr had more flavonoids in the stem than did CK.

Background: In Arabidopsis, a long day flowering plant, CONSTANS (CO) acts as a transcriptional activator of flowering under long day (LD) condition. In rice, a short day flowering plant, Hd1, the ortholog of CO, plays dual functions in respond to day-length, activates flowering in short days and represses flowering in long days. In addition, alleles of Hd1 account for ~ 44% of the variation in flowering time observed in cultivated rice and sorghum.
