Researchers find evidence of early genome duplications in conifers and other plants

center_img Journal information: Science Advances © 2015 Phys.org More information: Z. Li et al. Early genome duplications in conifers and other seed plants, Science Advances (2015). DOI: 10.1126/sciadv.1501084AbstractPolyploidy is a common mode of speciation and evolution in angiosperms (flowering plants). In contrast, there is little evidence to date that whole genome duplication (WGD) has played a significant role in the evolution of their putative extant sister lineage, the gymnosperms. Recent analyses of the spruce genome, the first published conifer genome, failed to detect evidence of WGDs in gene age distributions and attributed many aspects of conifer biology to a lack of WGDs. We present evidence for three ancient genome duplications during the evolution of gymnosperms, based on phylogenomic analyses of transcriptomes from 24 gymnosperms and 3 outgroups. We use a new algorithm to place these WGD events in phylogenetic context: two in the ancestry of major conifer clades (Pinaceae and cupressophyte conifers) and one in Welwitschia (Gnetales). We also confirm that a WGD hypothesized to be restricted to seed plants is indeed not shared with ferns and relatives (monilophytes), a result that was unclear in earlier studies. Contrary to previous genomic research that reported an absence of polyploidy in the ancestry of contemporary gymnosperms, our analyses indicate that polyploidy has contributed to the evolution of conifers and other gymnosperms. As in the flowering plants, the evolution of the large genome sizes of gymnosperms involved both polyploidy and repetitive element activity.

Premature toddlers can offer clues to their future IQ

first_img“We believe this is the first time a research paper has looked into the prediction of the IQ of adults over the age of 26, who were born very premature or with very low birth weight,” said lead researcher Dieter Wolke, professor at the University of Warwick in England, Britain. “The results indicate that assessing two year olds who were born very pre-term or very underweight will provide a reasonably good prediction to what their adult IQ will be,” Wolke noted. Also Read – ‘Playing Jojo was emotionally exhausting’In contrast, the research results found that the IQ of adults who were born full-term couldn’t be accurately predicted till the age of six. The study was conducted in southern Bavaria, Germany and followed children from birth into adulthood who were born between 1985-86. Two hundred and sixty babies born either very prematurely (before 32 weeks) or with very low birth weight (fewer than 1.5kgs) were compared with 229 babies who were born full-term. The findings were detailed in the journal pediatrics.last_img read more

The Work Perk That Matters More Than Free Food Gym Equipment or

first_img 2 min read Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now Move over, free food. At American companies, technology is the new perk.That’s according to a recent survey by Adobe Systems that revealed 81 percent of U.S. office workers value state-of-the-art technology above everything else — even more than a beautiful office or on-site amenities. Unfortunately, only a quarter of these same employees said their company’s technology was actually “ahead of the curve.”The advantages of new tech run deep. In the U.S., those who work at companies where the technology is “ahead of the curve” love their work about twice as much as those who work at tech-lagging companies, according to the study. They also say they feel more motivated and creative.Many employees aren’t just creative — they’re passionate. The study also revealed that one-third of U.S. office workers are “moonlighting,” or pursuing one or more jobs on top of their primary one. Aside from money, passion was the second driving force behind the increasing number of moonlighters, who predict the practice will become the norm in the future.In addition, the survey also showed that the average U.S. office worker thinks about work for 78 percent of their waking hours during a typical workday, versus 41 percent on a day off. This comes as no surprise, since 70 percent of these working Americans love what they do — to the point that 80 percent would continue working even if they won the lottery.Check out the infographic below for more insights on people’s relationship with work.Click to Enlarge May 26, 2016center_img This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience.
