Insect-deterring sorghum compounds may be eco-friendly pesticide

Compounds produced by sorghum plants to defend against insect feeding could be isolated, synthesized and used as a targeted, nontoxic insect deterrent, according to researchers who studied plant-insect interactions that included field, greenhouse and laboratory components. The researchers examined the role of sorghum chemicals called flavonoids —specifically 3-deoxyflavonoid and 3-deoxyanthocyanidins—in …

Deciphering the walnut genome

In a new study, a team of scientists at the University of California, Davis, and USDA’s Agricultural Research Service (ARS) used a unique approach to sequence the genomes of the English walnut and its wild North American relative by tapping into the capabilities of two state-of-the-art technologies: long-read DNA sequencing …

“Sour genes” in citrus fruits identified

Citrus fruits have always been known for their sour, zesty taste. With a little help from science, researches have finally identified what gives the lemon, orange, grapefruit, and other similar fruits their particular tangy flavour. Scientists from the University of Amsterdam found out that the sour taste of citrus fruits …

Aquaphotomics and resurrection plant Haberlea rhodopensis uncover the secrets of the unique desiccation tolerance

Тwo laboratories, leaders in different scientific fields – Prof. Dr Roumiana Tsenkova (Kobe University, Japan) performing in-vivo non-destructive near infrared (NIR) spectral monitoring of living systems and Prof. Dr Dimitar Djilianov (Agrobioinsitute, Sofia, Bulgaria) working on resurrection plants, especially H. rhodopensis joined their efforts to uncover the mechanisms of extreme …

Transcriptome reprogramming during severe dehydration contributes to physiological and metabolic changes in the resurrection plant Haberlea rhodopensis

Water shortages are the main limiting factor for global agriculture and ecosystems in general. During the evolution, different plants have developed the ability to survive relatively short periods of weaker or more severe water shortages. The so-called resurrection plants are, however, the only ones capable of surviving complete dehydration of …

An entire botanical garden of genomes

An article published recently in the Open-Access journal GigaScience provides data that effectively triples the number of plant species with available genome data. This mammoth amount of work comes on the back of the growing efforts of the scientific community to sequence more plant genomes to aid in understanding their …

Tomato plant aroma to protect crops

Tomato plants emit an aroma in order to ward off bacterial attacks. This volatile compound is hexenyl butyrate (HB), and according to testing by researchers at the Institute for Plant Molecular and Cellular Biology, Spain, it has great potential for protecting crops from infections, drought, etc. The finding has been …
