Phytoplasmas are pathogens of agriculturally important plants, including coconut, sugarcane, sandalwood, and cannabis, as well as horticultural crops like sweet cherry, peaches, and nectarines. They cause a wide variety of symptoms ranging from mild yellowing, small fruit, and reduced sugar content to death.

2024年2月23日 · Phytoplasmas are phloem-restricted plant-pathogenic bacteria transmitted by insects. They cause diseases in a wide range of host plants, resulting in significant economic and ecological losses worldwide. Research on phytoplasmas has a long history, with significant progress being made in the past 30 years.

Phytoplasma is the name given to microscopic, plant pathogenic, cell wall-less prokaryotes of the class Mollicutes that were formerly known as mycoplasma-like organisms or MLOs. Phytoplasmas are obligate parasites and have not been grown in axenic culture.

This review summarizes the history and current status of phytoplasma research, focusing on their discovery, molecular classification, diagnosis of phytoplasma diseases, reductive evolution of their genomes, characteristic features of their plasmids, molecular mechanisms of insect transmission, virulence factors, and chemotherapy.

Phytoplasmas are bacterial plant pathogens that can cause devastating yield losses in diverse low‐ and high‐value crops worldwide (Bertaccini, 2007; Lee et al., 2000). They are obligate symbionts of plants and insects, and in most cases need both hosts for dispersal in nature.

2021年5月19日 · Phytoplasmas are obligate phytopathogenic bacteria associated with devastating diseases in hundreds of crops across the world. They have been responsible for huge economic losses in many crop plants for decades now. Isolation and establishment of axenic culture of phytoplasma in complex media is a recent progress in phytoplasma research.

Phytoplasmas are mostly dependent on insect transmission for their spread and survival. The phytoplasma life cycle involves replication in insects and plants. They infect the insect but are phloem-limited in plants. Members of Ca. Phytoplasma asteris (16SrI group phytoplasmas) are found in 80 monocot and dicot plant species in most parts of the ...

2014年3月18日 · Phytoplasmas are plant pathogenic bacteria associated with devastating damage to over 700 plant species worldwide. It is agriculturally important to identify factors involved in their pathogenicity and to discover effective measures to …

2007年1月1日 · In this paper molecular, biological and epidemiological characteristics of phytoplasma associated with important diseases worldwide are described. Phytoplasma associated diseases are spread worldwide, and in several cases are associated with severe epidemic of very often quarantine importance.

Phytoplasmas are mycoplasma-like bacterial pathogens of plants that are transmitted by specific species of sap-feeding insects of the order Hemiptera [1–3]. You might find these chapters and articles relevant to this topic.
