HD-Zip (Homeodomain-Leucine Zipper) is a family of transcription factors unique to higher plants and plays a vital role in plant growth and development. Increasing research results show that HD-Zip transcription factors are widely involved in many life processes in plants. However, the HD-Zip transcription factor for cannabis, a valuable crop, has not yet been identified.

Apple rust caused by is a significant disease in China's main apple production areas. We evaluated the effects of temperature, moisture, and ultraviolet (UV) light on the germination, infection, and survival of teliospore horns and basidiospores under artificially controlled environmental conditions. The temperature required for the germination and infection of teliospores and basidiospores of ranged from 5 to 25°C, with an optimum temperature of approximately 17°C.

Article Synopsis
  • Glomerella leaf spot (GLS) is a new apple disease causing leaf drop and fruit blemishes, with effective control methods developed since 2018 using a combination of pyraclostrobin and tebuconazole.
  • A resistant strain of GLS has emerged in Shandong Province, China, in 2020, with 4.8% of isolates showing resistance due to a genetic mutation.
  • The study introduces a loop-mediated isothermal amplification (LAMP) assay to effectively detect this resistance, highlighting its practical importance for managing GLS in the field.

High-resolution-melting analysis (HRM) is a new technology derived from q PCR and is widely used in the study of polymorphism, genotyping, and single nucleotide mutation. Advantages of HRM include cost-effectiveness and time-efficiency over PCR-based genotyping. However, the application of HRM in the authentication of herbal products is still limited with few studies on the classification and identification of herbal products.

DNA barcoding method was conducted for the authentication of pollen materials due to difficulty of discriminating pollen materials bearing morphological similarity. In this study, a specific focus was to identify cattail pollen (Puhuang) and pine pollen (Songhuafen) samples from their adulterants which are frequently mixed-together. Regions of the internal transcribed spacer (ITS2) from 60 samples were sequenced, and new primers for cattail pollen were designed according to the sequence information.
