Biotic Stress

Biological stress refers to the general term of various biological factors that are unfavorable to the survival and development of plants. It is usually caused by infection and competition, such as diseases, pests, and weeds. In the GEPSdb database, we have collected and processed eight sets of microarray datasets and a set of RNA-seq datasets.

Carbon Dioxide

Carbon dioxide is one of the main greenhouse gases. In the past 200 years, the concentration of carbon dioxide in the atmosphere has risen from 280 μmol•mol-1 to the current 400 μmol•mol-1, and it may continue to rise this century. Whether high concentrations of carbon dioxide contribute to plant growth and crop yield depends on the concentration of carbon dioxide and the stress treatment time. In the GEPSdb database, we have included and processed two sets of microarray datasets.

Drought

Drought stress is one of the main limiting factors that inhibit the growth and development of plants. In order to adapt to the drought external environment, plants will initiate response mechanisms based on their own habits. In the GEPSdb database, we have collected and processed 15 sets of microarray datasets and 3 sets of RNA-seq datasets.

Frozen

Low temperature stress is a temperature environment that is lower than the lower limit of the optimal growth temperature for plants, which can be called low temperature stress. The lower limit of the optimum growth temperature varies with plant species and growth period. In the GEPSdb database, we have collected and processed 1 set of microarray datasets and 1 set of RNA-seq datasets.

Heat

In plants, heat stress caused by high temperature is usually defined as a temperature that is high enough to irreversibly damage the function or development of the plant for a long enough time. High temperature stress has adverse effects on plant growth, development, reproduction and yield, and various plant tissues are susceptible to high temperature damage. In the GEPSdb database, we have included and processed a set of RNA-seq datasets.

Hormone

Phytohormones are active substances that are induced by plant cells under specific environmental signals and can regulate plant physiological responses at low concentrations. In terms of cell division and elongation, tissue and organ differentiation, flowering and fruiting, maturation and senescence, dormancy and germination, and tissue culture in vitro, the growth, development and differentiation of plants are regulated separately or in coordination with each other. In the GEPSdb database, we have collected and processed 6 sets of microarray datasets and 1 set of RNA-seq datasets.

Hypoxia

Plant growth requires oxygen, and low oxygen stress is the most common problem encountered in plant growth. Oxygen is an indispensable condition for the normal growth and development of plants. Plants absorb oxygen to perform respiration, drive the synthesis of ATP and NADP, maintain the reducing power required for cell growth, and constitute the core of plant life metabolism. In the GEPSdb database, we have collected and processed a set of microarray datasets.

Metal

The damage mechanism of heavy metals to plant biofilms. Heavy metals are inducers of lipid peroxidation. When heavy metals treat plants, the production and balance of free radicals in cells are persecuted, leading to the production of a large number of active oxygen free radicals and destroying the structure of the membrane. and function. In the GEPSdb data, we collected and processed 2 sets of microarray datasets and 2 sets of RNA-seq datasets.

Nitrogen

Nitrogen is an essential nutrient for plant growth, and it is an integral part of every living cell. Plants need a lot of nitrogen, and the effect of nitrogen on plant growth and development is very obvious. When nitrogen is sufficient, plants can synthesize more protein to promote cell division and growth. Therefore, the leaf area of plants grows fast, and more leaf area can be used for photosynthetic storage. In the GEPSdb data, we have collected and processed 3 sets of microarray datasets.

Ozone

The influence of ozone on plants is closely related to the accumulation of metabolites in plants. Ozone stress triggers various defense and protection mechanisms of plants, stimulates the antioxidant system, affects the membrane system, changes the absorption of carbon and mineral nutrients in the body, causes their redistribution, and induces deep changes in its gene expression. In the GEPSdb database, we have included and processed 3 sets of microarray datasets.

Salt

Salt stress refers to the high osmotic potential that plants are affected by growing in high-salinity habitats. Studying the salt stress regulation mechanism of plants and breeding salt-tolerant plants are conducive to agricultural production and yield increase, and it is helpful to the management and improvement of saline-alkali land. In the GEPSdb database, we have collected and processed 3 sets of microarray datasets and 1 set of RNA-seq datasets.

Tree-wound

Mechanical stress refers to the changes in the state or activity of cells or organisms, such as movement, secretion, enzyme products, and gene expression after plants are damaged by external machinery. In the GEPSdb database, we have collected and processed 7 sets of microarray datasets.

UV

The thinning of the stratospheric ozone layer and the enhancement of ultraviolet B caused by human activities are one of today’s global environmental problems. Processed 1 set of RNA-seq datasets.
