When cells get metals in small excess, mechanisms of avoidance occur, such as exclusion,
sequestration, or compartmentation. When the excess reaches sub-lethal concentrations …

This Current Topic focuses on light-dependent protochlorophyllide oxidoreductase (POR,
EC 1.3. 1.33). POR catalyzes the penultimate reaction of chlorophyll biosynthesis, ie, the …

Since the publication of the third edition of the Handbook of Plant and Crop Stress,
continuous discoveries in the fields of plant and crop environmental stresses and their …

The interaction between zinc and cadmium was investigated in tomato plants (Solarium
lycopersicum). Ten-day-old seedlings were treated with 10 μmol/L CdCl 2 associated to …

The present experiment was conducted to appraise the role of different seed priming agents
in circumventing the negative impact of chromium (Cr) toxicity on canola plants. Chromium …

Cadmium (Cd) stress may cause serious physiological, ultramorphological and biochemical
anomalies in plants. Cd-induced physiological, subcellular and metabolic alterations in two …

Unbound tetrapyrroles, ie protochlorophyllide (Pchlide), chlorophyllide and chlorophylls,
bring the risk of reactive oxygen species (ROS) being generated in the initial stages of …

Cyanobacteria, the first photoautotrophs have remarkable adaptive capabilities against most
abiotic stresses, including Cd. A model cyanobacterium, Anabaena sp. PCC 7120 has been …

An increasing number of soils of poor quality with unbalanced metal concentrations are
used worldwide for crop cultivation. Even though plants are able to develop strategies to …

The in vivo chlorophyll (Chl) fluorescence spectra of Solanum lycopersicum leaves were
recorded in the spectral region 650–800nm using a spectroscopic method based on …
