Abstract
Food security for a growing world population remains one of the most challenging tasks. Rapid climate change accelerates the loss of arable land used for crop production, while it simultaneously imposes increasing biotic and abiotic stresses on crop plants. Analysis and molecular understanding of the factors governing stress tolerance is in the focus of scientific and applied research. One plant is often mentioned in the context with stress resistance—Chenopodium quinoa. Through improved breeding strategies and the use of next generation approaches to study and understand quinoa’s salinity tolerance, an important step towards securing food supply is taken.

Strategies to Improve Crop YieldHow to feed the world’s population is still one of the most challenging questions
Rapid climate change intensifies abiotic stresses and limits the time for a crop to adapt to new environmental conditions
PAMP-triggered immunity (PTI) and effector-triggered immunity (ETI) induce a first response against biotic stress which leads to an increase in cytoplasmic calcium concentration, the production of reactive oxygen species (ROS) and the activation of mitogen-activated protein kinases (MAPKs)
Summary
How to feed the world’s population is still one of the most challenging questions. A United. Crops are exposed to different biotic and abiotic stresses: Biotic stresses include pathogen infection and herbivore attack [3], while abiotic stresses are environmental factors that compromise plants and reduce their productivity. These factors include extreme changes in temperature, water, nutrients, gases, wind, radiation and other environmental conditions. Generation techniques are used to identify and study stress-tolerant plants This includes “omics” approaches, which are very effective molecular methods to investigate biochemical, physiological and metabolic strategies of plants exposed to biotic and abiotic stresses.
