Article Synopsis
- Polygonatum odoratum is a traditional Chinese herbal plant affected by a leaf spot disease observed in Hunan Province, China, during 2021 and 2022, impacting 60-70% of the plants.
- The disease starts with small reddish-brown spots that develop into larger tan lesions, and researchers collected diseased leaf samples for pathogen isolation, using specific methods to examine the fungi.
- Identification of the pathogen revealed it as Fusarium fujikuroi, confirmed through morphological analysis and molecular techniques using specific primers for genetic amplification.
Article Synopsis
- - Polygonatum odoratum, a perennial herb in the Liliaceae family and a traditional Chinese medicinal plant, has been found to contain various active compounds such as polysaccharides and flavonoids.
- - In May to June 2022, a stem spot disease was identified in P. odoratum plants in Changsha, China, affecting 40-50% of the plants and causing serious economic losses by stunting growth.
- - Researchers collected symptomatic stem samples to identify pathogens, isolating two fungal strains that displayed rapid growth on a culture medium, which may contribute to understanding and managing the disease affecting these plants.
Lilium × formolongi is an important cut flower species that is able to flower within a year following seed propagation, with flower induction that is very sensitive to the photoperiod. Cryptochromes are blue/UV-A light receptors that regulate many important plant growth and development processes, including photoperiodic flowering. In this study, we isolated the cryptochrome 1 (CRY1) gene from L.
