Almost twenty years ago, the process of RNA silencing was discovered in plants, whereby small fragments of RNA inactivate a portion of a gene during protein synthesis. These fragments–called microRNAs (abbreviated as miRNAs)–have since been shown to be essential at nearly every stage of growth and development in plants, from the production of flowers, stems, and roots to the ways plants interact with their environment and ward off infection.
Flowers come in a multitude of shapes and colors. Now, an international research team has proposed the novel hypothesis that trade-offs caused by different visitors may play an important role in shaping this floral diversity.
A research team has created a computer model to understand how plants store energy in the thylakoid membrane, a key structure to photosynthesis in plant leaves. The team confirmed the accuracy of the mathematical model with lab experiments.
Scientists at Oxford and in Malaysia have just described a species of fairy lantern completely new to science.
Scientists have discovered how plants manage to live alongside each other in places that are dark and shady. Moderate shade or even the threat of shade – detected by phytochrome photoreceptors – causes plants to elongate to try to outgrow the competition.
An international study has revealed the structure of a membrane-remodeling protein that builds and maintains photosynthetic membranes. These fundamental insights lay the groundwork for bioengineering efforts to strengthen plants against environmental stress, helping to sustaining human food supply and fight against climate change.
The Musa genus, which includes over 70 species and around 1,000 cultivars of bananas, represents a globally important source of food and livelihoods. MusaNet collects and shares global resources on banana (Musa) across the whole value chain – from collecting germplasm to post-harvest qualities.
As well as bright colours and subtle scents, flowers possess many invisible ways of attracting their pollinators, and a new study shows that bumblebees may use the humidity of a flower to tell them about the presence of nectar, according to recent research.
The first plant embryo gene expression atlas at the single cell level was developed by a team of researchers. The work is a milestone on the way to uncovering the molecular mechanisms that determine how the most fundamental plant cell-types are established at the beginning of life.
Findings reveal how plants use a blend of genes, geography, demography and environmental conditions to evolve defense chemicals over time.
