Temperature-induced hormesis in plants

Temperature-Induced Chemical Defects in Higher Plants.

source. The hypothesis of the chemical cure of clinmatic lesions states in effect that unfavorable climatic conditions may cause plants to become heterotrophic for one or more essential metabolites. Experimentally the concept can be tested by applying metabolites to plants growing at different temperature levels. Data cannot be held to support the hypothesis unless it can be shown that the comp...

The occurrence of hormesis in plants and algae.

This paper evaluated the frequency, magnitude and dose/concentration range of hormesis in four species: The aquatic plant Lemna minor, the micro-alga Pseudokirchneriella subcapitata and the two terrestrial plants Tripleurospermum inodorum and Stellaria media exposed to nine herbicides and one fungicide and binary mixtures thereof. In total 687 dose-response curves were included in the database....

Freeze Tolerance and Low Temperature-induced Genes in Bermudagrass Plants

Effect of temperature on geminivirus-induced RNA silencing in plants.

Short-interfering RNAs (siRNAs), the molecular markers of posttranscriptional gene silencing (PTGS), are powerful tools that interfere with gene expression and counter virus infection both in plants and animals. Here, we report the effect of temperature on geminivirus-induced gene silencing by quantifying virus-derived siRNAs and by evaluating their distribution along the virus genome for isola...

Exercise-induced hormesis may help healthy aging.

Hormesis plays a critical role in producing some major benefits derived from physical exercise. However whether these known cellular mechanisms are applicable to ameliorate age-related deterioration of muscle function is not entirely clear. The present communication proposes that antioxidant adaptation, the peroxisome proliferator-activated receptor gamma coactivator (PGC)-1alpha activated mito...
