“…For example, both metabolic rate and cold tolerance were enhanced in atsugari and fumin mutants due to the altered transcription level of the corresponding and/or downstream genes (Takeuchi et al, 2009;Ueno et al, 2012). Secondly, Smp30 (Dca), known as a candidate gene for cold tolerance, was up-regulated during the cold acclimation at 15°C for a few days in D. melanogaster originally reared at 25°C, a condition similar to that of our study (Goto, 2000). Finally in this study, the deacclimation and reacclimation experiments showed that the switches between acclimatized and non-acclimatized physiological states in flies required at least several days (Tables 3 and 4), suggesting that a rapidly triggered calcium signaling during rapid cold hardening for example was unlikely to be the underlying molecular mechanism.…”

“…For example, Goto (2000) showed that the half lethal temperature (temperature that kills half of the individuals for 24 hours) was 1°C for the adult flies with an acclimation at 15°C for 1 day, whereas it was 3°C for those without acclimation. Bubliy et al (2002) showed that when flies reared at 25°C were acclimatized at 11°C for 5 days before an exposure to 0°C for 24 hours, the survival rate of the acclimatized flies was about 5-7 times higher than that of the control flies.…”

“…Such phenomenon is called acclimation and is observed as an improved survival rate in a cold temperature (say ~0°C) after experiencing a mildly lower temperature than the usual living temperature (Salt, 1961). Rako and Hoffmann (2006) classified this type of plastic response into three categories: "rearing acclimation" as a continuous response to a lower temperature than the optimal living temperature during the course of development (e.g., Ohtsu et al, 1999), "cold acclimation" as a response to a moderately low temperature for a few days to several weeks (e.g., Goto, 2000;Bubliy et al, 2002) and "rapid cold hardening," as a rapid response to a sub-lethal temperature for a very short time from a few minutes to hours (e.g., Czajka and Lee, 1990). Since the seasonal temperature fluctuation is relatively mild in the temperate regions, the cold acclimation is likely to be an effective strategy for insects like Drosophila to adapt to temperature changes in their habitats.…”

Cold tolerance and metabolic rate increased by cold acclimation in <i>Drosophila albomicans</i> from natural populations

Cold acclimation is one of the important factors in temperature adaptation for insects needing to make rapid adjustment to the seasonal temperature changes in their living environment. In a fruit fly species, Drosophila albomicans, which has a tropical origin and currently has a wide geographic distribution extended into Asian temperate regions, cold tolerance in terms of survival time at 1°C of adult flies reared at 25°C was substantially improved by a cold acclimation at 20°C for several days. Examining 29 isofemale lines from widely distributed natural populations, we observed a substantial variation in their acclimation response. However, the acclimation response was not necessarily stronger in the strains from the recently colonized temperate regions. A significantly stronger acclimation response was detected in male flies of the temperate strains when compared to those of the tropical strains. D. albomicans also showed stronger cold tolerance compared to its closely related species belonging to the D. nasuta subgroup. Among these strains, we detected a strong positive correlation between the cold tolerance change and the metabolic rate change upon the cold acclimation, suggesting their strong physiological association regulated by common genetic factors, which may have been the target of natural selection for the temperature adaptation. The response to deacclimation and reacclimation suggested that a systematic change in gene expressions is the main molecular mechanism for the cold acclimation to have effects on the cold tolerance and metabolic rate changes.

“…It is a member of the SMP-30 family that includes proteins such as anterior fat body proteins and regucalcin. These proteins are Ca 21 -binding proteins with multifunctional roles in the regulation of intracellular Ca 21 homeostasis and regulation of intracellular signalling [50][51][52].…”

The secreted salivary proteome of the pea aphid Acyrthosiphon pisum characterised by mass spectrometry

et al. 2009

Nine proteins secreted in the saliva of the pea aphid Acyrthosiphon pisum were identified by a proteomics approach using GE-LC-MS/MS and LC-MS/MS, with reference to EST and genomic sequence data for A. pisum. Four proteins were identified by their sequences: a homolog of angiotensin-converting enzyme (an M2 metalloprotease), an M1 zinc-dependant metalloprotease, a glucose-methanol-choline (GMC)-oxidoreductase and a homolog to regucalcin (also known as senescence marker protein 30). The other five proteins are not homologous to any previously described sequence and included an abundant salivary protein (represented by ACYPI009881), with a predicted length of 1161 amino acids and high serine, tyrosine and cysteine content. A. pisum feeds on plant phloem sap and the metalloproteases and regucalcin (a putative calcium-binding protein) are predicted determinants of sustained feeding, by inactivation of plant protein defences and inhibition of calcium-mediated occlusion of phloem sieve elements, respectively. The amino acid composition of ACYPI009881 suggests a role in the aphid salivary sheath that protects the aphid mouthparts from plant defences, and the oxidoreductase may promote gelling of the sheath protein or mediate oxidative detoxification of plant allelochemicals. Further salivary proteins are expected to be identified as more sensitive MS technologies are developed.

“…Substantially less work has been conducted for cold-stress resistance, possibly because our knowledge of the relevant candidate genes and pathways is limited. Goto (2000Goto ( , 2001 showed that Senescence marker protein-30 (Smp-30) and Frost (Fst) are both upregulated in response to cold acclimation or cold stress. Anderson et al (2003) demonstrated an association between clinal molecular variation in Hsr-omega and cold-stress resistance.…”

Quantitative trait loci for thermotolerance phenotypes in Drosophila melanogaster

2006

For insects, temperature is a major environmental variable that can influence an individual's behavioral activities and fitness. Drosophila melanogaster is a cosmopolitan species that has had great success in adapting to and colonizing diverse thermal niches. This adaptation and colonization has resulted in complex patterns of genetic variation in thermotolerance phenotypes in nature. Although extensive work has been conducted documenting patterns of genetic variation, substantially less is known about the genomic regions or genes that underlie this ecologically and evolutionarily important genetic variation. To begin to understand and identify the genes controlling thermotolerance phenotypes, we have used a mapping population of recombinant inbred (RI) lines to map quantitative trait loci (QTL) that affect variation in both heat-and cold-stress resistance. The mapping population was derived from a cross between two lines of D. melanogaster (Oregon-R and 2b) that were not selected for thermotolerance phenotypes, but exhibit significant genetic divergence for both phenotypes. Using a design in which each RI line was backcrossed to both parental lines, we mapped seven QTL affecting thermotolerance on the second and third chromosomes. Three of the QTL influence cold-stress resistance and four affect heat-stress resistance. Most of the QTL were trait or sex specific, suggesting that overlapping but generally unique genetic architectures underlie resistance to low-and high-temperature extremes. Each QTL explained between 5 and 14% of the genetic variance among lines, and degrees of dominance ranged from completely additive to partial dominance. Potential thermotolerance candidate loci contained within our QTL regions are identified and discussed.
