Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a primer set for detection of a deciduous inflorescences of persimmon trees, and a primer set thereof for use in detection of Mycosphaerella nawae and uses thereof.

The present invention relates to a primer set and a use thereof for detecting or diagnosing a persimmon foliar infection, and more particularly, to a primer set capable of specifically detecting or diagnosing persimmon round foliar foliar disease bacteria. A composition for diagnosing a persimmon round discolor; Diagnostic kit; And to a method for detecting a deciduous flower leaf of the persimmon using the same.

Circular leaf spot (CLS) is the most severe disease in the persimmon tree. It infects the leaves in the form of ascospores from the middle of May to early August, and leaves the leaves early after the end of August. It occurs mainly on the leaves and rarely occurs on the throat. The first black round spot is formed on the leaf, and as the lesion enlarges, the inside of the lesion is light brown or reddish-brown, and the border of the lesion is black green. Thereafter, the circular lesion fuses and grows into an irregular lesion. Leaves with severe disease occur early and fall off. This greatly affects the growth and yield of trees and is susceptible to the East Sea.

Mycosphaerella nawae is a pathogenic bacterium that causes rot fungi of the persimmon tree. It belongs to the fungal genus of the fungus, and forms a conidia and conidia. Cryptocyte is a dark brown to egg-shaped, and contains several sacs. The optimum temperature for growth of pathogenic bacteria is 20 ~ 25 ℃. Artificial cultivation is possible but it is very difficult to separate. The inventive conditions and transmission route of persimmon leaves are known to swell in the form of hyphae or mycelium in deciduous diseased lesions and then spread to the pseudothecium in April and scattered in May to July , And the symptom is manifested in September-October. The pathogens that enter the persimmon leaves develop after a certain latency period, and they are believed to have a long latency period of 2 to 4 months, and not to transmit the second infection. June to July, many occur in rainy weather and rainfall management is poor.

Persimmon leaves of persimmon are most common diseases in persimmon growing fields in Korea. Persimmon leaves are the most harmful diseases in persimmon cultivation areas in the southern region. This disease has a very long time until the time when the infection becomes symptomatic and once the disease has occurred, there is no way to control it, so there are many farmers who are suffering from damage each year without establishing clear control measures until now. When the disease is caught, the severely infected leaves are deciduous leaves, which is a terrible disease that leads to the degradation of fruit trees, which leads to a decrease in productivity, such as immature fruit and decolorization. Most of these diseases are infected by primary infectious agents, and the latency period from infection to symptoms is very long (latency period of about 90-120 days after infection), which makes it difficult to control the disease. Therefore, it is necessary to treat pre-existing fungicides in accordance with the timing of aspergillus spores in order to control the effective deciduous disease of persimmon leaves. In order to control the disease, persimmon growers are spraying more than 6 disinfectants a year, which increases the economic burden on growers.

Therefore, in order to minimize the damage of the persimmon leaves, it is indispensable to prevent the disease before the disease develops. Therefore, it is urgently required to develop a technology capable of quickly and quickly diagnosing the infection of the persimmon leaves .

Accordingly, the present inventors have sought to find a method for quickly and accurately diagnosing the infection of the persimmon leaves of the Japanese persimmon tree. As a result, Mycosphaerella nawae gene specific sequence, and that when the PCR is carried out by using the primer, it is possible to accurately diagnose the persimmon round-leaf lance disease, and the present invention has been completed.
