“…Adams et al analyzed the toxic effect of cesium in plants. High concentrations of cesium inhibited plant growth inducing the jasmonate pathway and thereby probably modified potassium uptake machineries [8]. The differential role of defense response pathways, the unfolded protein response (UPR) and the steroid response element ( SREBP ) was studied by Bedoya-Perez et al in the mosquito Aedes aegypti using the Cry11Aa toxin [9].…”

In the special issue “Signaling Molecules and Signal Transduction in Cells” authors were invited to submit papers regarding important and novel aspects of extra- and intracellular signaling which have implications on physiological and pathophysiological processes. These aspects included compounds which are involved in these processes, elucidation of signaling pathways, as well as novel techniques for the analysis of signaling pathways. In response, various novel and important topics are elucidated in this special issue.

“…These two different kinds of abiotic stresses were induced for fenugreek seedlings at the early stage of growth. The environmental stresses like drought (Hamidi and Safarnejad, 2010) and heavy metals (Adams et al, 2013;Smiri et al, 2013) are known to cause oxidative damage to plants either directly or indirectly by triggering an increased level of production of reactive oxygen species (ROS) which include superoxide radical (O .-), hydroxyl radical (OH .-) and hydrogen peroxide (H 2 O 2 ). They cause damage to the biomolecules such as membrane lipid, proteins, enzymes, nucleic acid among others (Mishra and Singhal, 1992).…”

In the present investigation, the impact of drought and heavy metal in fenugreek was critically monitored. Fenugreek seedlings were exposed to 1-bar polyethylene glycol (PEG) solution (osmotic stress) and 10 ppm solution of HgCl 2 (heavy metal). Within 3 days of seedling growth, mercury exposure induced relatively high level of adverse impact of root growth and biomass production where cell division was significantly reduced measured by mitotic index and development of root vascular bundle was affected indicating negative impact on nutrient transport chain. Mercury stress showed a five-fold increase in malonaldehyde (MAD) production along with antioxidant enzyme peroxidase (POD) activity and mercury stress showed simultaneous and lower antioxidant activity compared to osmotic stress increased activity in super oxide dismutase (SOD) and catalase (CAT) indicates that mercury pollution leads to serious damage in cell membrane through accumulation of lipid peroxides and POD activity to quench it whereas osmotic stress is not so serious and adopt the mechanism to quench the superoxides by SOD and followed by the detoxification of H 2 O 2 by catalase and formation of lower level of MAD.

“…Nevertheless, the results showed that 42 K accumulation from root uptake and the expression of genes related to the root K + uptake were almost constant (Figs 2 and 3B–F). It has been reported that the induction of AtHAK5 was enhanced by K + deficiency78 or by Cs + applications when there was sufficient K + 39. Therefore, the slight increase in PttHAK-like1 expression under SD6 might be a response to K + starvation during the long growth period.…”

Short day length-induced alteration of potassium (K) localization in perennial trees is believed to be a mechanism for surviving and adapting to severe winters. To investigate the relationship between cesium (Cs) and K localizations, a model tree poplar, hybrid aspen T89, was employed. Under short day length conditions, the amount of 137Cs absorbed through the root and translocated to the root was drastically reduced, but 42K was not. Potassium uptake from the rhizosphere is mediated mainly by KUP/HAK/KT and CNGC transporters. In poplar, however, these genes were constantly expressed under short-day conditions except for a slight increase in the expression a KUP/HAK/KT gene six weeks after the onset of the short-day treatment. These results indicated that the suppression of 137Cs uptake was triggered by short day length but not regulated by competitive Cs+ and K+ transport. We hypothesize that there are separately regulated Cs+ and K+ transport systems in poplar.
