Chrysanthemum stunt viroid (CSVd), a noncoding RNA, is known to cause chrysanthemum stunt disease, which affects the yield of flowers. To gain insights into CSVd replication, infection, and the reasons for the spreading of CSVd disease in chrysanthemum plants, we prepared linear CSVd RNA and analyzed its ability to cause disease in chrysanthemum plants. We found that linear CSVd replicated as efficiently as CSVd RNA isolated from the infected chrysanthemum plants. Additionally, the linear CSVd RNA was evaluated for its ability to infect other plants as well, which revealed that CSVd has a wide host range for its replication. Importantly, the CSVd isolated from these hosts is infectious to chrysanthemum plants, and thus potentially contributes to the spreading of the disease to chrysanthemum plants.

Nowadays, the development of plant extracts as corrosion inhibitors to protect metals from corrosion is a popular research direction. However, given the vast diversity of plant species in nature, it is imperative to explore effective methods to improve screening efficiency in order to quickly identify the corrosion inhibition potential of plants. In this work, a new strategy for developing plant-extracted eco-friendly corrosion inhibitors based on the family and genus of plants is proposed.

Background/objectives: Chrysanthemum (), a key ornamental and medicinal plant, presents challenges in cultivar identification due to high phenotypic similarity and environmental influences. This study assessed the genetic diversity and discrimination of 126 spray-type chrysanthemum cultivars.
Methods: About twenty-three simple sequence repeat (SSR) markers were screened for the discrimination of 126 cultivars, among which six SSR markers showed polymorphic fragments.

The flowering time of Chrysanthemum morifolium predominantly depends on day length but is also sensitive to ambient temperature. However, the mechanisms underlying the response of chrysanthemum to ambient temperature are mainly unknown. This study identified a MADS-box transcription factor called CmFLC-like, a representative low ambient temperature-responsive factor induced in chrysanthemum leaves and shoot apical meristems at 15°C.

Light is one of the most important environmental factors that affect plant growth and development. It also stimulates anthocyanin biosynthesis in plants. However, the precise molecular mechanisms through which light regulates anthocyanin biosynthesis, particularly in non-model plant species, remain poorly understood.

Temporal decline in microRNA miR156 expression is crucial for the transition to, and maintenance of, the adult phase and flowering competence in flowering plants. However, the molecular mechanisms underlying the temporal regulation of miR156 reduction remain largely unknown. Here, we investigated the epigenetic mechanism regulating the temporal silencing of cin-MIR156 in wild chrysanthemum (Chrysanthemum indicum), focusing on the role of the lysine-specific demethylase CiLDL1 and the nuclear factor Y complex.
