Metabolomics is a cutting-edge omics technology that identifies metabolites in organisms and their environments and tracks their fluctuations. This field has been extensively utilized to elucidate previously unknown metabolic pathways and to identify the underlying causes of metabolic changes, given its direct association with phenotypic alterations. However, metabolomics inherently has limitations that can lead to false positives and false negatives.

Article Synopsis
  • - Nicotiana benthamiana, an important model organism in plant research, has undergone genomic sequencing that revealed significant genetic variations within the species, leading to the need for a more accurate genome sequence based on its geographic origin.
  • - This study presents a detailed genome assembly of the N. benthamiana LAB strain from Korea (NbKLAB), offering a high-quality, chromosome-level assembly with 19 chromosomes and 2,762 Mb, which shows notable genetic differences compared to the commonly used NbLAB360 strain.
  • - The NbKLAB genome assembly includes 46,215 protein-coding genes and boasts a completeness score of 99.5%, significantly improving the quality assessment metrics, thus providing a valuable resource for further

Does believing that "effort doesn't pay" in society shape how people view dishonest-illegal transgressions? Across five studies, we show that when people view societal success as non-meritocratic-that is, more dependent on luck and circumstances than on hard work-they are more lenient in their moral judgements of dishonest-illegal transgressions. Perceiving society as non-meritocratic predicted greater justifiability of dishonest-illegal transgressions in the United States (Study 2), and across 42 countries (N = 49,574; Study 1). And inducing participants to view society as non-meritocratic increased justifiability of others' dishonest-illegal transgressions, via greater feelings of sympathy (Studies 3 and 4).

Improvements in long read DNA sequencing and related techniques facilitated the generation of complex eukaryotic genomes. Despite these advances, the quality of constructed plant reference genomes remains relatively poor due to the large size of genomes, high content of repetitive sequences, and wide variety of ploidy. Here, we developed the de novo sequencing and assembly of high polyploid plant genome, Hibiscus syriacus, a flowering plant species of the Malvaceae family, using the Oxford Nanopore Technologies and Pacific Biosciences Sequel sequencing platforms.

The COVID-19 pandemic presents challenges to psychological well-being, but how can we predict when people suffer or cope during sustained stress? Here, we test the prediction that specific types of momentary emotional experiences are differently linked to psychological well-being during the pandemic. Study 1 used survey data collected from 24,221 participants in 51 countries during the COVID-19 outbreak. We show that, across countries, well-being is linked to individuals' recent emotional experiences, including calm, hope, anxiety, loneliness, and sadness.

Article Synopsis
  • Plant cells can change their function and regenerate into new plants through the combined effects of two hormones: auxin and cytokinin.
  • The study focuses on the role of a specific gene called WUSCHEL (WUS), which influences the ability of different potato genotypes to regenerate shoots.
  • Findings indicate that higher levels of WUS lead to better regeneration rates, and adjusting cytokinin types can enhance regeneration, particularly in genotypes with lower efficiency.

Americans venerate rags-to-riches stories. Here we show that people view those who rich more positively than those rich and expect the Became Rich to be more sympathetic toward social welfare (Studies 1a and b). However, we also find that these intuitions are misguided.

Background: The genus in the Araliaceae family has been used as traditional medicinal plants worldwide and is known to biosynthesize ginsenosides and phytosterols. However, genetic variation between species has influenced their biosynthetic pathways is not fully understood.

Methods: Simultaneous analysis of transcriptomes and metabolomes obtained from adventitious roots of two tetraploid species ( and ) and two diploid species ( and ) revealed the diversity of their metabolites and related gene expression profiles.

People believe that effort is valuable, but what kind of value does it confer? We find that displays of effort signal moral character. Eight studies ( = 5,502) demonstrate the nature of these effects in the domains of paid employment, personal fitness, and charitable fundraising. The exertion of effort is deemed morally admirable (Studies 1-6) and is monetarily rewarded (Studies 2-6), even in situations where effort does not directly generate additional product, quality, or economic value.

Long terminal repeat retrotransposons (LTR-RTs) make up a considerable portion of plant genomes. New insertions of these active LTR-RTs modify gene structures and functions and play an important role in genome evolution. Therefore, identifying active forms of LTR-RTs could uncover the effects of these elements in plants.

Fusarium wilt (FW) is a fungal disease that causes severe yield losses in radish production. The most effective method to control the FW is the development and use of resistant varieties in cultivation. The identification of marker loci linked to FW resistance are expected to facilitate the breeding of disease-resistant radishes.
