It is said that 10 to 15 % of the human race ’s farming product loss is triggered by diseases . And since 70 - 80 % of this industrial plant disease is triggered by filamentlike fungus , protect crop from filamentous fungus is an crucial topic in effectively feed the world universe . In order for morbific fungi to taint plants , they must break through the epidermal cells of the plant and overrun the interior . In other words , plant epidermal mobile phone act as the first barrier to hold on the attack of pathogenic fungi in the environment . So what sort of defense functions do cuticular cells have ?

Interestingly , it was be intimate that the cuticle of plants moderate little chloroplasts that are not so tangled in photosynthesis . However , it was unclear what function it had . Why are there lowly chloroplasts in the epidermis of plants that do not contribute much to photosynthesis ?

Assistant Professor Hiroki Irieda of the Faculty of Agriculture , Shinshu University and Professor Yoshitaka Takano , Graduate School of Agriculture , Kyoto University , found that small chloroplasts in the epidermis of plant control the entry of fungal pathogen . The duo discovered that the small chloroplast move inside the mobile phone dramatically to the surface layer in response to the fungous attack and is involved in such defense response .

In this bailiwick , the couple first investigate what kind of   pathogenic fungi   the epidermic chloroplast answer to . As a upshot , they establish that multiple pathogenic filamentous fungi cause aerofoil migration of cuticular chloroplast . Interestingly , it was also find that these pathogenic filiform kingdom Fungi were the so - called ' nonadapted ' and were stymie from obtrude upon   dermal cellphone . On the other deal , adapted morbific fungus is more likely to occupy the cuticle in plants in which the epidermal chloroplasts have stopped migrate to the aerofoil layer .

Next , they follow in finding plant protein postulate in the surface migration of epidermal chloroplasts . When a plant that overproduces this protein was created by gene transfer introduction , dermal chloroplasts did not move to the open layer against pathogenic threadlike fungus . In this transgenic flora , the immunity to the epidermal intrusion of pathogenic filamentlike fungus kingdom is reduced . It was also found that pathogenic fungus are more likely to invade the epidermis in plant life in which the epidermal chloroplast have stop migrate to the surface layer . These resolution point that the migration of epidermal chloroplast to the surface bed is imply in the defense reply that blocks the encroachment of infective fungi .
