Is drought tolerance a domestication trait in tepary bean?: Allelic diversity at abiotic stress responsive genes in cultivated Phaseolus acutifolius A. Gray and its wild relatives

Some of the major impacts of climate change are expected in the poorest regions of the world where drought stress and nutrient deficiency are already a main issue. Legumes are an essential food crop for the poorest because of their high dietary protein and micronutrient contents. However, they are generally drought susceptible. Therefore, our goal in this study was to explore allele diversity at abiotic stress responsive candidate genes in the only drought tolerant cultivated bean species of the genus Phaseolus, tepary bean (P. acutifolius A. Gray) and its related species P. parvifolius Freytag. Specifically, we estimated drought tolerance in 52 tepary bean s.l. geo-referenced germplasm accessions from the P. acutifolius–parvifolius clade using climate information, and used this estimated drought stress index to examine allele correlations with Asr2, Dreb2B and ERECTA-encoding candidate genes for drought tolerance. Genetic clustering showed that cultivated and wild P. acutifolius were intermingled with P. acutifolius var. tenuifolius and P. parvifolius, signifying that allele diversity at candidate genes for drought tolerance was not scarce in tepary bean s.l. Dreb2B and ERECTA-encoding genes harbored signatures of directional/purifying selection, likely in favor of adaptive alleles selectively advantageous because each had two SNPs significantly correlated (p-value < 0.05) with habitat drought stress at six and 12 months. These results suggest that tepary bean s.l. is a reservoir of novel alleles at candidate genes for drought tolerance, as expected for a drought-tolerant species that originated in warmer and arid environments. Abiotic stress responsive candidate genes also exhibit comparable patterns of selective signatures when comparing orthologous across species, which speaks for a predominant role of gene sub-functionalization likely due to ecological constrains. Our study therefore corroborates that the candidate gene approach is still an effective alternative for marker validation across a broader genetic basis of germplasm accessions. Further efforts to determine the genetic architecture of drought tolerance will unlock novel alleles hidden in a crop with limited modern relevance as tepary bean, but capable of acting as a donor in backcrossing and genome editing strategies with elite common bean lines aiming to meet the imminent demands of a drier world.

Are juveniles as tolerant to salinity stress as adults?: A case study of Northern European, Ponto-Caspian and North American species

Aim: Global biodiversity and ecosystems are highly impacted by anthropogenic activities, such as climate change and introduction of non-indigenous species. As numerous species from the Ponto-Caspian region have established in the North and Baltic Seas, as well as in the Laurentian Great Lakes, there have been large number of studies examining environmental tolerance of these species to determine their future potential to spread. However, many of those studies were conducted only on adult stages, while neglecting the possibility that early life history stages might not be equally resilient. Location: Northern European, Ponto‐Caspian and North American regions. Methods: To determine if juveniles would demonstrate the same environmental tolerance as their parents, we examined the salinity tolerance of adults and juveniles of one Northern European (Gammarus salinus), one Ponto-Caspian (Pontogammarus maeoticus) and one North American species (Gammarus tigrinus). Additionally, we compared our study to that of Paiva et al. (2018), who tested the salinity tolerance of the same species using only adults. Results: Our study determined that both adults and juveniles of all three species tolerated wide ranges of salinity, with juveniles of G. salinus tolerating only slightly narrower salinity range than their parents, while those of P. maeoticus and G. tigrinus much narrower range. Additionally, we determined better survival and higher growth rates of juveniles of G. salinus in higher salinities, and better survival of P. maeoticus in lower salinities. Main conclusions: Based on juvenile salinity tolerance, our study further supported findings of Paiva et al. (2018), where Northern European species may be adapted to marine, while Ponto-Caspian to lower saline and freshwater environments. The North American species is probably adapted to intermediate salinities. As juveniles do not tolerate the same salinity stress as adults, we emphasize the importance of testing all life-history stages when predicting species resilience to environmental stressors.

Data from: A positive genetic correlation between hypoxia tolerance and heat tolerance supports a controversial theory of heat stress

We used quantitative genetics to test a controversial theory of heat stress, in which animals overheat when the demand for oxygen exceeds the supply. This theory, referred to as oxygen- and capacity-limited thermal tolerance, predicts a positive genetic correlation between hypoxia tolerance and heat tolerance. We demonstrate the first genetic correlation of this kind in a model organism, Drosophila melanogaster. Genotypes more likely to fly under hypoxic stress (12% O2) were also more likely to fly under heat stress (39°C). This finding prompts new questions about mechanisms and limits of adaptation to heat stress.

Long term environmental stability drives reduced stress tolerance in salt lake invertebrates

The capacity of species to tolerate physical stressors is critical in a world of increasing environmental instability, however, past selective environments should dramatically impact on future stress tolerance, particularly in isolated populations. Through stabilising selection, long-term environmental stasis may reduce physiological tolerance, creating an evolutionary legacy where populations are less fit if environments change. Few empirical studies have investigated this evolutionary legacy of past selection, and of particular interest whether stabilising selection in a benign environment reduces stress tolerance in natural systems. Here we use multiple populations of salt-lake invertebrates (Coxiella striata, Austrochiltonia subtenuis) with either stable or fluctuating environmental histories to investigate the relationship between stabilising selection and environmental stress resistance. Tolerance to both salinity and temperature stress were examined in invertebrate populations from lakes with long-term (decadal) stable environments and compared with populations from lakes with extreme salinity variations. Individuals from stable environments demonstrated significantly lower survival under both increasing salinity and temperature stresses when compared with environmentally unstable populations. Our results support the hypothesis that the evolutionary legacy from stabilising selection in constant environments leads to reduced stress tolerance. This finding demonstrates that under an increasingly variable climate, the evolutionary legacies of populations will be critical for future survival and adaptation.

Evolution of sex-specific heat stress tolerance and larval Hsp70 expression in populations of Drosophila melanogaster adapted to larval crowding

The ability to tolerate temperature stress is an important component of adult fitness. In holometabolous insects like Drosophila melanogaster, adult stress resistance can be affected by growth conditions experienced during the larval stages. While evolution under crowded larval conditions is known to lead to the correlated evolution of many adult traits, its consequences on adult heat stress tolerance have not been investigated. Therefore, in the present study, we assessed the adult heat stress tolerance in populations of D. melanogaster adapted to a stressful larval crowding environment. We used replicate populations of D. melanogaster, selected for adaptation to larval crowding stress (MCUs), for more than 230 generations, and their respective controls (MBs). Larvae from selected and control populations were grown under crowded and uncrowded conditions and their adult heat shock resistance at two different temperatures was measured. Further, we compared Hsp70 expression in crowded and uncrowded larvae of both populations and also measured the Hsp70 expression after a mild-heat treatment in adults of selected and control populations. Our results showed that adaptation to larval crowding leads to the evolution of Hsp70 gene expression in larval stages and improves adult heat-stress tolerance ability in males, but not in females.
