Growth of pea (Pisum sativum L.) plants with 50 µm CdCl2 for 15 d produced a reduction in
the number and length of lateral roots, and changes in structure of the principal roots …

Arsenic (As) negatively affects plant development. This study evaluates how the application
of silicon (Si) can favor the formation of adventitious roots in rice under arsenate stress (AsV) …

Nitric oxide (NO), polyamines (PAs), diamine oxidases (DAO) and polyamine oxidases
(PAO) play important roles in wide spectrum of physiological processes such as …

Peroxisomes are key metabolic organelles, which contribute to cellular lipid metabolism, eg
the β-oxidation of fatty acids and the synthesis of myelin sheath lipids, as well as cellular …

Hydrogen sulfide (H 2 S) is a novel gaseous signaling molecule in response to adversity
stress. Melatonin (MT) is a multifunctional molecule that plays an important role in regulating …

Reactive oxygen and nitrogen species are involved in a plethora of cellular responses in
plants; however, our knowledge on the outcomes of oxidative and nitrosative signaling is still …

As with all organisms, plants must respond to a plethora of external environmental cues.
Individual plant cells must also perceive and respond to a wide range of internal signals. It is …

Nitric oxide (NO), a free radical generated in plant cells, belongs to a family of related
molecules designated as reactive nitrogen species (RNS). When an imbalance of RNS …

Background Peroxisomes are highly dynamic, metabolically active organelles that used to
be regarded as a sink for H2O2 generated in different organelles. However, peroxisomes …

The organization of redox signaling and the use of nitric oxide (NO) to transmit information,
modulate biological processes or create cellular damage are highly complex. Recent reports …
