Published A roadmap for gene regulation in plants
(via sciencedaily.com) Original source For the first time, researchers have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's physiological traits. Their work reveals unprecedented insights into gene regulatory networks and identifies a new library of DNA parts that can be used to optimize plants for bioenergy and agriculture.
Published 'Shoebox' satellites help scientists understand trees and global warming
(via sciencedaily.com) Original source As scientists try to understand the effect of climate on trees, advances in imaging technology are helping them see both the whole forest and every individual tree. High-resolution images taken by cubesats, small, shoebox-sized devices launched into low Earth orbit, are helping environmental scientists make more precise measurements about trees' response to a warming climate.
Published Plant extracts used by indigenous people hold promise in treatment of ataxia
(via sciencedaily.com) Original source Researchers have discovered that extracts from plants used by the Kwakwaka'wakw First Nations peoples in their traditional botanical medicine practices are able to rescue the function of ion channel proteins carrying mutations that cause human Episodic Ataxia.
Published AI reveals hidden traits about our planet's flora to help save species
(via sciencedaily.com) Original source Machine learning can help extract important information from the huge numbers of plant specimens stored in herbaria, say scientists.
Published Bridging traditional economics and econophysics
(via sciencedaily.com) Original source How do asset markets work? Which stocks behave similarly? Economists, physicists, and mathematicians work intensively to draw a picture but need to learn what is happening outside their discipline. A new paper now builds a bridge.
Published From cross to self-pollination
(via sciencedaily.com) Original source Biologists provide evidence for an alternative genetic mechanism that can lead to plants becoming self-pollinators.
Published Fossil study sheds light on famous spirals found in nature
(via sciencedaily.com) Original source A 3D model of a 407-million-year-old plant fossil has overturned thinking on the evolution of leaves. The research has also led to fresh insights about spectacular patterns found in plants.
Published How will a warming world impact the Earth's ability to offset our carbon emissions?
(via sciencedaily.com) Original source New work deploys a bold new approach for inferring the temperature sensitivity of ecosystem respiration -- which represents one side of the equation balancing carbon dioxide uptake and carbon dioxide output in terrestrial environments. This will improve scientists' models for climate change scenarios.
Published Photosynthesis, key to life on Earth, starts with a single photon
(via sciencedaily.com) Original source A cutting-edge experiment has revealed the quantum dynamics of one of nature's most crucial processes.
Published Plant remediation effects on petroleum contamination
(via sciencedaily.com) Original source Initial choices about fertilization and grass seeding could have a long-lasting effect on how plants and their associated microbes break down pollution in petroleum-contaminated soils.
Published Team finds reliable predictor of plant species persistence, coexistence
(via sciencedaily.com) Original source Ecological scientists have long sought ways to measure and predict how specific plant communities will fare over time. Which species in a diverse population will persist and coexist? Which will decline? What factors might contribute to continuing biodiversity? Researchers report on a new method for determining whether pairs or groups of plant species are likely to coexist over time.
Published Older trees accumulate more mutations than their younger counterparts
(via sciencedaily.com) Original source A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating and maintaining genetic diversity than short-lived trees.
Published Saving moths may be just as important as saving the bees
(via sciencedaily.com) Original source Night-time pollinators such as moths may visit just as many plants as bees, and should also be the focus of conservation and protection efforts, a new study suggests.
Published The other side of the story: How evolution impacts the environment
(via sciencedaily.com) Original source Researchers show that an evolutionary change in the length of lizards' legs can have a significant impact on vegetation growth and spider populations on small islands in the Bahamas. This is one of the first times, the researchers say, that such dramatic evolution-to-environment effects have been documented in a natural setting.
Published Symbiotic and pathogenic fungi may use similar molecular tools to manipulate plants
(via sciencedaily.com) Original source Symbiotic and pathogenic fungi that interact with plants are distantly related and don't share many genetic similarities. Comparing plant pathogenic fungi and plant symbiotic fungi, scientists at the Sainsbury Laboratory Cambridge University (SLCU) have discovered that these remote relatives are using a similar group of proteins to manipulate and live within plants.
Published Phenomenal phytoplankton: Scientists uncover cellular process behind oxygen production
(via sciencedaily.com) Original source According to new research, the amount of oxygen in one of 10 breaths was made possible thanks to a newly identified cellular mechanism that promotes photosynthesis in marine phytoplankton. The new study identifies how a proton pumping enzyme (known as VHA) aids in global oxygen production and carbon fixation from phytoplankton.
Published Study leads to milestone advances in understanding lethal bronzing of palm trees
(via sciencedaily.com) Original source Scientists have identified a key chemical associated with lethal bronzing (LB) infected palm trees. LB is a bacterial disease that kills more than 20 species of palm trees in the Southern United States and Caribbean and has been devastating the Florida green industries for nearly two decades.
Published Plants can distinguish when touch starts and stops, study suggests
(via sciencedaily.com) Original source Even without nerves, plants can sense when something touches them and when it lets go, a study has found. In a set of experiments, individual plant cells responded to the touch of a very fine glass rod by sending slow waves of calcium signals to other plant cells, and when that pressure was released, they sent much more rapid waves. While scientists have known that plants can respond to touch, this study shows that plant cells send different signals when touch is initiated and ended.
Published Light conveyed by the signal transmitting molecule sucrose controls growth of plant roots
(via sciencedaily.com) Original source Researchers shows how information about the quantity of absorbed light passes from the leaves to the roots. Photosynthetic sucrose not only supplies roots with carbohydrates but also acts as a signal transmitter for light-dependent root architecture.
Published That's not nuts: Almond milk yogurt packs an overall greater nutritional punch than dairy-based
(via sciencedaily.com) Original source In a nutritional comparison of plant-based and dairy yogurts, almond milk yogurt came out on top, according to new research.
