The RUBY reporter for visual selection in soybean genome editing
2024-04-11
(Press-News.org)
This study is led by Professor Wensheng Hou (Institute of Crop Sciences, Chinese Academy of Agricultural Sciences, Beijing, China). The authors engineered a novel expression vector designed to facilitate gene editing and enable visual confirmation of successful modifications. To achieve this, the authors used RUBY reporter which harnessed the ability to convert tyrosine into a vivid red betalain pigment. This breakthrough allowed to visually confirm gene expression in soybean plants without the need for specialized equipment.
By utilizing this innovative color-based screening system, the authors could quickly assess whether genetic modifications were inherited during the early cotyledon phase of the offspring. Transgene-free homozygous mutants exhibited a distinct green coloration, simplifying to be selected from the transformed aubergine seedlings.
Through the implementation of this reporter system, the authors efficiently identified a transgene-free gmwaxy mutant in the T1 generation, characterized by higher amylopectin content. The authors anticipate that future research will uncover even more promising biotechnological applications in soybean improvement and genetic modification.

New evidence of one of the first cities in the Pacific shows they were established much earlier than previously thought, according to new research from The Australian National University (ANU).
The study used aerial laser scanning to map archaeological sites on the island of Tongatapu in Tonga.
Lead author, PhD scholar Phillip Parton, said the new timeline also indicates that urbanisation in the Pacific was an indigenous innovation that developed before Western influence.
“Earth structures were being constructed in Tongatapu around AD 300. This is 700 years earlier than previously thought,” ...

Octopuses have been around for hundreds of millions of years, but did you know that most only live for a few years, dying soon after mating or laying eggs?
Until now that hasn’t been a problem, but octopus catches have doubled in recent decades as the world strives to meet the nutritional demands of a rising global population.
How do we ensure octopus fisheries remain sustainable, protecting the longevity of this ancient animal while guaranteeing the world doesn’t go hungry?
An accurate, reliable, cost effective and easy-to-use method to determine an octopus’s ...

A single low dose injection of esketamine given immediately after childbirth reduces major depressive episodes in individuals with depressive symptoms during pregnancy (prenatal depression), finds a clinical trial published by The BMJ today.
The results suggest that low dose esketamine should be considered in new mothers with prenatal depressive symptoms.
Depression is common during pregnancy and shortly after giving birth and can have several adverse effects on new mothers and their infants.
Esketamine ...

Tucson, AZ—Neural systems, shaped by millions of years of evolution, enable living things to perceive and react to their surroundings. But how does the nervous system adapt to today’s unprecedented challenge of rapid and extensive human-caused environmental changes, including exposure to pollution, toxins, and increasingly unpredictable environments?
In 2025, Research Corporation for Science Advancement, The Paul G. Allen Frontiers Group, and The Kavli Foundation will launch a Scialog initiative to catalyze research to explore ...

Years after the U.S. began to slowly emerge from mandatory COVID-19 lockdowns, more than half of older adults still spend more time at home and less time socializing in public spaces than they did pre-pandemic, according to new University of Colorado Boulder research.
Participants cited fear of infection and “more uncomfortable and hostile” social dynamics as key reasons for their retreat from civic life.
“The pandemic is not over for a lot of folks,” said Jessica Finlay, an assistant professor of geography whose findings are revealed in a series of new papers. ...

Ancient Egyptians were known for their religious beliefs and astronomical knowledge of the Sun, Moon, and planets, but up until now it has been unclear what role the Milky Way played in Egyptian religion and culture.
A new study by a University of Portsmouth astrophysicist sheds light on the relationship between the Milky Way and the Egyptian sky-goddess Nut.
Nut is goddess of the sky, who is often depicted as a star-studded woman arched over her brother, the earth god Geb. She protects the earth from being flooded by the encroaching waters of the void, and plays a key role in the solar cycle, swallowing the Sun as it sets at dusk ...

UNIVERSITY PARK, Pa. — The size of an individual snack piece not only influences how fast a person eats it, but also how much of it they eat, according to a new study led by researchers at Penn State. With nearly a quarter of daily calorie intake in the United States coming from snacks, these findings may have implications for helping people better understand how eating behavior impacts calorie and sodium intake.
The team of food scientists investigated how the size of pretzels influences eating behavior — overall intake, eating rate, bite size and snacking duration — and found that people eat larger pretzels ...
