Silicon (Si) is the second most abundant element in soil, where its availability to plants can
exhilarate to 10% of total dry weight of the plant. Si accumulation/transport occurs in the …

Both biotic and abiotic stresses are major constrains to agricultural production. Under stress
conditions, plant growth is affected by a number of factors such as hormonal and nutritional …

Abiotic stressful conditions of the environment such as soil salinity, drought, flood, heat, cold,

▪ Abstract Photoreduction of dioxygen in photosystem I (PSI) of chloroplasts generates
superoxide radicals as the primary product. In intact chloroplasts, the superoxide and the …

Reactive O 2 species (ROS) are produced in both unstressed and stressed cells. Plants
have well‐developed defence systems against ROS, involving both limiting the formation of …

Adaptation to environmental changes is crucial for plant growth and survival. However, the
molecular and biochemical mechanisms of adaptation are still poorly understood and the …

Drought and salinity are two widespread environmental conditions leading to low water
availability for plants. Low water availability is considered the main environmental factor …
