GM rice provides natural source of antihypertensive agents

Researchers were successful in developing a genetically modified (GM) rice that can reduce high blood pressure when consumed, without any side effects. Scientists from the Chinese Academy of Sciences genetically modified a variety of rice by introducing a gene that consisted of nine angiotensin converting enzyme (ACE)-inhibitory peptides plus a …

Bumblebees Poke Leaves to Help Flowers Bloom Faster

Scientists from Switzerland’s Department of Environmental Systems Sciences found bumblebee’s secret to accelerating flower production when there is pollen shortage: bite the plant’s leaves. According to their research article in Science, three species of bumblebees use their mouthparts in a characteristic way to damage mustard and tomato leaves leading to …

The Role of Plant Biotechnology Against SARS-CoV-2

A scientific team from Europe compiled and reviewed the existing plant technologies being used to currently combat SARS-CoV-2, the virus responsible for the COVID-19 pandemic. They published their paper with the aim of highlighting technologies where plants can make major contributions: diagnostic reagents for virus test kits, vaccine production, and …

Zeaxanthin‐rich tomato fruit developed through genetic manipulations of carotenoid biosynthesis

Researchers from The Hebrew University of Jerusalem developed zeaxanthin-rich tomato fruit using transgenic metabolic engineering and conventional breeding techniques. Providing food sources with high zeaxanthin concentration could help curb the progression of age-related macular degeneration (AMD), one of the leading causes of blindness. Zeaxanthin has several benefits to human health …

Brightest engineered plants glow throughout life cycle

Nature Biotechnology reports genetically engineered tobacco plants that glow brightly during its entire lifetime. The findings of the study conducted by researchers from Planta and the Russian Academy of Sciences could be used in the development of imaging tools for plants. Compared to previously reported glowing plants, these plants shine …

Scientists improve antioxidant content of maize

Researchers from the Chinese Academy of Agricultural Sciences improved the tocopherol composition of maize to maximize its use for human and livestock health. The results are published in Transgenic Research. The seeds of many plant species, including maize, have high gamma (γ)-tocopherol but low alpha (α)-tocopherol contents, α-tocopherol, a form …
