This review deals with the adaptive mechanisms that plants can implement to cope with the
challenge of salt stress. Plants tolerant to NaCl implement a series of adaptations to …

Recent reports show ethylene‐dependent reductions in stomatal sensitivity to abscisic acid
(ABA) under ozone stress. These changes reduce stomatal control of plant water loss in …

Increasing consciousness regarding the nutritional value of olive oil has enhanced the
demand for this product and, consequently, the expansion of olive tree cultivation. Although …

When plants are subject to a variety of stresses they often exhibit symptoms of exposure to
ethylene. Although this relationship usually results from induction of ACC synthase thus …

Citrus is the main fruit tree crop in the world and therefore has a tremendous economical,
social and cultural impact in our society. In recent years, our knowledge on plant …

In this article we review evidence for a variety of long-distance signaling pathways involving
hormones and nutrient ions moving in the xylem sap. We argue that ABA has a central role …

H2O2 serves an important stress signaling function and promotes stomatal closure, whereas
ascorbic acid (Asc) is the major antioxidant that scavenges H2O2. Dehydroascorbate …

Facilitation takes place when plants ameliorate the environment of their neighbours, and
increase their growth and survival. Facilitation occurs in natural ecosystems as well as in …

Abscission consists in the detachment of entire vegetative and reproductive organs due to
cell separation processes occurring at the abscission zones (AZs) at specific positions of the …

Plants are continuously exposed to various environmental stresses, which cause alteration
in every physiological and biochemical pathway. Plants have evolved several mechanisms …
