Temperature-dependent alterations in metabolic enzymes and proteins of three ecophysiologically different species of earthworms

Abstract

The effects of varying temperatures (12 -44° C) on the specific activity of cytoplasmic malate dehydrogenase ((cMDH)

Biochemical response and vermiremediation assessment of three earthworm species (Alma millsoni, Eudrilus eugeniae and Libyodrilus violaceus) in soil contaminated with a glyphosate-based herbicide

“…In this study, we observed that activities of GST and LDH increased in the three earthworm species exposed to GBH relative to the unexposed. GST is a cytosolic enzyme which performs a crucial role in the detoxification, biotransformation and neutralization of several pesticides and endogenous metabolic by-products in the body (Hayes et al, 2005;Tiwari et al, 2016), and LDH, being a major glycolytic enzyme present in earthworms tissue (Shekari et al, 2008), is an enzymatic indicator of stress exposure which provide energy to the organism within a short period of time (Tripathi et al, 2011). Therefore, the increase in the activities of GST and LDH in the earthworm species exposed to GBH as recorded in this present study could be linked to the physiological adjustment of the body to cope with likely oxidative stress and some other biochemical adjustments imposed by the herbicide.…”

Differences in protein expression among five species of stream stonefly (Plecoptera) along a latitudinal gradient in Japan

“…Stoneflies are probably distributed at higher altitudes (e.g., Prenda & Gallardo‐Mayenco, ) because of their adaptation to low salinity (Gallardo‐Mayenco, ), low water temperature (Brittain, ), and high oxygen conditions (Brittain, ). Moreover, salinity stress (Kozova, Prasil, & Vitamvas, ), low temperature tolerance (Tripathi, Kachhwaha, Dabi, & Bandooni, ), and oxygen tolerance (Salin, Auer, Rey, Selman, & Metcalfe, ) exert demands on energy resources and energy metabolism in several organisms, such as plants, birds, and earthworms. Therefore, future studies using different organisms with wider taxonomic ranges are necessary to determine more general patterns and conclusions.…”

“…Studies have examined specific chromosomal regions under selection by scanning genome‐wide patterns of DNA polymorphisms (Storz, ), but links between genes and environmental conditions remain poorly understood. A major approach for exploring these links is gene expression analysis using RNA transcriptomics (de Nadal, Ammerer, & Posas, ; Somervuo et al., ). However, this approach has several limitations, including observing gene interactions (Cox & Mann, ; Gstaiger & Aebersold, ), important regulatory signals (Lu, Vogel, Wang, Yao, & Marcotte, ), and conformational changes in adaptation‐related genes (Cox & Mann, ) that only occur downstream of transcription and thus cannot be detected using transcriptomic approaches.…”

Thermal Stress Induced Alterations in Tissue Protein, Lipid Peroxidation and Activities of Lactate Dehydrogenase, Acetylcholinesterase and Catalase in the Earthworm Eudrilus eugeniae (Kinberg)

“…Collet et al [21] have observed a significant alteration in the population and metabolism of soil invertebrates including earthworms in forest soil due to increased soil temperature after a forest fire and reported that those higher than optimal environmental temperatures negatively influence metabolic rate and survival of the worms. Tripathi et al [22] have reported a significant variation in the tissue protein of the earthworms Metaphire posthuma, Perionyx sansbaricus and Lampito mauritii exposed to a temperature range from 12°C to 44°C. They have observed an increase in protein from 12°C to 20°C and subsequent decrease up to 44°C.…”
