The defense mechanism of plant

Abstract

According to the state of food security and nutrition, Hunger has increased in many countries in which the economy has slowed down, mostly in middle-income countries. If nothing changes, the immense challenge of achieving the Zero Hunger Target by 2030. The causes of food scarcity might include factors such as unavailability of food due to less production of particular crops/vegetables (due to attack of pests/microbes), it becomes harder to fulfill the basic needs of life especially for poor. Therefore, we need to primarily focus on understanding the interaction between plants and microbes at the molecular level and underlying mechanisms of plant disease and which will help out to solve the global needs of food and resources. Plants have a natural defense mechanism/immune system to react to infections which subdivides into two parts. The first part identifies and reacts to molecules common to different classes of microbes, including non-pathogen. The function of the second part is to react to pathogens virulence factors, either directly or by affecting the host targets. We can also see the intricacies or reciprocation between plants and pathogen attackers. A vast and deep comprehension of plant defense mechanisms will defiantly solve the issue, like food scarcity.
