Plants exhibits different types of abiotic and biotic stresses continuously throughout its life cycle. Being sessile, plants can’t avoid the stresses through escaping their natural habitat but can tolerate to a certain extent through modifying its physiology and metabolism. In addition, plants are also capable in formation of new molecules and molecular mechanisms to withstand in stressed condition. Different types of physiological and molecular mechanisms i.e.; ion homeostasis and compartmentalization, synthesis of compatible solutes, activation of antioxidants, hormonal regulation is developed in plant to combat with stressed condition of plants. Increment of crop production is crucial to feed the increasing population throughout the world. Both abiotic and biotic stress hinder the crop production to a great extent.
Nowadays, many researches are undertaken to escape the stresses or to induce tolerance in plants. Scientists are trying to improve the tolerance mechanisms by exogenous application of substances. To meet up the demand of upcoming food crisis, more high yielding crop varieties should be introduced, incorporating the knowledge of stress tolerance mechanism.
In this special issue, we aimed at accumulating the recent progress in plant biology research. Articles on recent advances in plant biology (original research papers, short communications, reviews, mini-reviews) are welcome.

Cadmium (Cd) causes oxidative stress, which leads to the oxidation of various biomolecules by the production of reactive oxygen species (ROS) to facilitate programmed cell death (PCD). The antioxidant defense system fails to detoxify ROS when it is produced in excess. Nitric oxide (NO), a gaseous free radical and a phytohormone, regulates various physiological processes of plants. Therefore, this work was undertaken to study the effects of the application of exogenous sodium nitroprusside (SNP, a NO donor) on growth parameters, oxidative stress, accumulation of secondary metabolites, and activities of antioxidant enzymes under Cd stress. Mild (50 µM) and severe (200… More >

Drought stress is one of the major environmental obstacles that limit the production and development of apples (Malus domestica Borkh.). The role of melatonin is well known in the protection of plants under environmental stresses. In this study, we investigated the effect of melatonin on apple rootstock M. hupehensis Rehd under drought stress. The results showed that drought inhibited the growth of M. hupehensis and dramatically reduced root surface area, root volume, the number of tips and forks, and root diameter. Drought-induced growth inhibition was significantly decreased by adding melatonin. Net photosynthetic rate (Pn), intercellular CO2 concentration (Ci), stomatal conductance… More >
