This Plant Derivative Inhibit SARS-CoV-2 Entry (Botany)

Leave a comment

Using a bioactivity-guided chromatographic approach, in addition to mass-spectrometry (MS), Guillermo H. Jimenez-Aleman and colleagues identified the antiviral metabolite as Pheophorbide a (PheoA), a porphyrin chlorophyll derivative very similar to animal antiviral metabolite Protoporphyrin IX, in the bryophyte Marchantia polymorpha. Their study recently appeared in BioRxiv. To confirm the antiviral potential of PheoA, a commercially … Continue reading This Plant Derivative Inhibit SARS-CoV-2 Entry (Botany) →

In Plant Cells, A Conserved Mechanism For Perceiving Mechanical Force Resides in Unexpected Location (Botany)

Leave a comment

Minuscule tunnels through the cell membrane help cells to perceive and respond to mechanical forces, such as pressure or touch. A new study in the journal Science is among the first to directly investigate what one type of these mechanosensitive ion channels is doing in the tip-growing cells in moss and pollen tubes of flowering plants, and … Continue reading In Plant Cells, A Conserved Mechanism For Perceiving Mechanical Force Resides in Unexpected Location (Botany) →

Duckweed and Amazon Shrub Reveal Potential For Bioenergy Production (Botany)

Leave a comment

Duckweed and Senna reticulata, common name mata-pasto (“pasture killer”), plants frequently found in Brazil’s North region, have significant potential for use as raw material to produce bioenergy, according to studies by researchers affiliated with the National Institute of Science and Technology (INCT) for Bioethanol, one of the INCTs supported by FAPESP and the National Council for Scientific and Technological Development (CNPq) … Continue reading Duckweed and Amazon Shrub Reveal Potential For Bioenergy Production (Botany) →

How ERF1 Regulates Flowering? (Botany)

Leave a comment

Floral initiation must be strictly regulated to achieve reproductive success. ETHYLENE RESPONSE FACTOR1 (ERF1) functions as an important integrator of several phytohormone signals to regulate both development and stress responses. However, the underlying mechanism for its role in flowering-time regulation remained unclear.  In a study published in Journal of Integrative Plant Biology, researchers from the Xishuangbanna Tropical Botanical Garden … Continue reading How ERF1 Regulates Flowering?

Researchers Identify A Gene That Regulates The Angle Of Root Growth In Corn (Botany)

Leave a comment

The discovery of a gene that regulates the angle of root growth in corn is a new tool to enable the breeding of deeper-rooting crops with enhanced ability to take up nitrogen, according to an international team of researchers, led by Penn State. The gene, called ZmCIPK15—a moniker indicating where it is located in the … Continue reading Researchers Identify A Gene That Regulates The Angle Of Root Growth In Corn (Botany) →

Juicy Past Of Favorite Okinawan Fruit Revealed (Botany)

Leave a comment

Highlights Citrus fruits from the mandarin family have important commercial value but how their diversity arose has been something of a mystery Researchers analyzed the genomes of the East Asian varieties and found a second center of diversity in the Ryukyu Islands along with the previously known center in the mountains of southern China They … Continue reading Juicy Past Of Favorite Okinawan Fruit Revealed (Botany) →

Blushing Plants Reveal When Fungi Are Growing in Their Roots (Botany)

Leave a comment

Scientists have created plants whose cells and tissues ‘blush’ with beetroot pigments when they are colonised by fungi that help them take up nutrients from the soil. We can now follow how the relationship between the fungi and plant root develops, in real-time, from the moment they come into contact. — Sebastian Schornack This is … Continue reading Blushing Plants Reveal When Fungi Are Growing in Their Roots (Botany) →

Tomato Fruits Send Electrical Warnings to the Rest of the Plant When Attacked by Insects (Botany)

Leave a comment

A recent study in Frontiers in Sustainable Food Systems shows that the fruits of a type of tomato plant send electrical signals to the rest of the plant when they are infested by caterpillars. Plants have a multitude of chemical and hormonal signaling pathways, which are generally transmitted through the sap (the nutrient-rich water that moves through … Continue reading Tomato Fruits Send Electrical Warnings to the Rest of the Plant When Attacked by Insects (Botany) →

Arrival of Land Plants Changed Earth’s Climate Control System (Botany)

Leave a comment

The arrival of plants on land about 400 million years ago may have changed the way the Earth naturally regulates its own climate, according to a new study led by researchers at UCL and Yale. The carbon cycle, the process through which carbon moves between rocks, oceans, living organisms and the atmosphere, acts as Earth’s … Continue reading Arrival of Land Plants Changed Earth’s Climate Control System (Botany) →
