The development of research in this area led to the identification of metal hyper-accumulators, which could be utilized for reclamation of contaminated soil through phytomining. Concurrently, breeding and biotechnological approaches can enhance the remediation efficiency. Phytoremediation technology, combined with other reclamation technologies/practices, can provide clean soil and water to the ecosystem.Mating system transitions from self-incompatibility (SI) to self-compatibility (SC) are common in plants. In the absence of high levels of inbreeding depression, SC alleles are predicted to spread due to transmission advantage and reproductive assurance. We characterized mating system and pistil-expressed SI factors in 20 populations of the wild tomato species Solanum habrochaites from the southern half of the species range. We found that a single SI to SC transition is fixed in populations south of the Rio Chillon valley in central Peru. In these populations, SC correlated with the presence of the hab-6 S-haplotype that encodes a low activity S-RNase protein. We identified a single population segregating for SI/SC and hab-6. Intrapopulation crosses showed that hab-6 typically acts in the expected codominant fashion to confer SC. However, we found one specific S-haplotype (hab-10) that consistently rejects pollen of the hab-6 haplotype, and results in SI hab-6/hab-10 heterozygotes. We suggest that the hab-10 haplotype could act as a genetic mechanism to stabilize mixed mating in this population by presenting a disadvantage for the hab-6 haplotype. This barrier may represent a mechanism allowing for the persistence of SI when an SC haplotype appears in or invades a population.In this study, the author evaluated two adult age groups of the Mexican rivulus Millerichthys robustus with body size asymmetries to determine the strategies used by an annual killifish during agonistic interactions of different ontogenetic stages. To achieve this goal, the author first characterized the ethogram of agonistic interactions of M. robustus composed of seven behavioural units in males and five behavioural units in females. The author then analysed agonistic interaction strategies used by males and females with body size asymmetries in two groups of different adult ages that represent different ontogenetic stages (a) just after sexual maturity was reached, at 5 weeks of age, and (b) near natural death, at 24 weeks of age. The agonistic behaviour patterns of M. robustus were compatible with the logic of mutual assessment. Large males had an advantage during their interactions in both age groups, winning all of the encounters. Nonetheless, there was more aggression in 5-week-old fish encounters. In addition, small 24-week-old fish were more aggressive than small 5-week-old fish. These changing strategies may be because of the cost-benefits required during a fight at each ontogenetic stage. In the female encounters, size did not predict winners, as both small and large fish won a similar number of encounters, and some contests remained unresolved regardless of age group. There was a tendency for small females of any age to risk more than males in fights to maintain reproductive fitness.This study explores the intermediary role of anticipated shame, guilt, and norms in the association between empathy and the likelihood of a specific uncooperative act theft by finding. read more Empirical evidence supports a negative association between empathy and a broad range of uncooperative behaviors. Some studies suggest that empathy reduces noncooperation via intermediary factors such as empathy and moral emotions shame and guilt. Inspired by Martin Hoffman’s empathy-based theory of moral development, we propose a testable model in which individual differences in empathic concern and perspective-taking are positively related to anticipated guilt, shame, and conduct-specific moral norm, which in turn reduce the likelihood of theft by finding. Data were collected from a region-wide cross-sectional sample of adolescents and young adults in the Dutch-speaking part of Belgium in 2019 (N = 3591). Overall, our propositions were corroborated. Structural equation modeling suggests that empathic concern inhibits the likelihood of theft by finding via anticipated guilt-shame. The discussion focuses on a better understanding of the relationship between empathy, moral dimensions, and uncooperative choices.There is a paucity of data regarding racial disparities in the survival of patients with indolent non-Hodgkin lymphomas (iNHL) in the contemporary time-period. Hence, we sought to determine whether racial disparities exist in the survival of patients with iNHLs in the US. We included 68 059 adult patients with follicular lymphoma (FL, n = 41 943), marginal zone lymphoma (MZL, n = 22 485), and lymphoplasmacytic lymphoma/Waldenström macroglobulinemia (LPL/WM, n = 3631) who were diagnosed in the US between 2000 and 2017. Race was categorized as White, Black, Asian/Pacific Islander, or American Indian/Alaska Native (API/AI). The primary outcome was relative survival (RS), which was estimated using flexible parametric survival models. The RS estimates varied according to race and disease histology but were consistently lower for racial minorities, including those diagnosed during the most recent 5-year time-period of 2012-2017. On multivariable analysis for RS, Black patients with FL had a 32% higher excess mortality rate compared to White patients [adjusted excess hazard ratio (aEHR), 1.32; 95% CI, 1.15-1.51; p less then  .001], corresponding to a difference of 55 (95% CI, 24-86) excess deaths per 10 000 person-years. For MZL, Black patients had a 40% higher excess mortality rate compared to White patients (aEHR 1.40; 95% CI, 1.18-1.66; p less then  .001), corresponding to a difference of 62 (95% CI, 26-98) excess deaths per 10 000 person-years. No significant racial differences were detected for patients with WM. The greatest disparity was seen for younger Black patients with FL. Our findings highlight the need for interventions to improve the outcomes of Black patients with iNHLs, particularly younger Black patients with FL.
