Leguminous plants, like peas, beans, and various species of clover, obtain the organic nitrogen they need for their growth from symbiotic soil bacteria via specialized structures in their roots. Now researchers explain an evolutionary step in the symbiosis between plants and nitrogen-fixing bacteria.
A team of researchers has taken another step to facilitate the genomic editing of plants. Their breakthrough will enable the use of CRISPR systems, which opens the door to obtain new, more productive and nutritive varieties that are more resistant to plagues, pathogens and other environmental threats such as drought or extreme temperatures.
We are in the middle of a pandemic, but the experience is different for everyone. This was expressed beautifully in an original tweet by Damian Barr, later expanded by another author into a poem. “We are not all in the same boat. We are all in the same storm. Some are on super-yachts. Some have just the one oar.”
In the face of the Covid-19 pandemic and the mounting threat of climate change, forests and trees are vital for the rural poor in countries around the world. However, the poor are rarely able to capture the bulk of benefits from forests. A global science assessment analyses how forests can realize their potential to reduce poverty in a fair and lasting manner.
An international team of researchers led by biologists has examined how seed formation is coordinated with fruit growth. In their report, they explain the genetic control mechanisms underlying the process. If you open up a pea pod, you will find that all of the peas inside are the same size and the same distance apart. The same is true of princess beans, runner beans and soybeans as well as various other peas and beans, and it also applies to non-pulses. This is surprising because both the seed size and number and the pod size differ substantially from one variety to the next.
As plant scientists, we are all only too aware of the ‘plant blindness’ that pervades the world. The Global Plant Council aims to raise awareness about the importance of plant science (and its scientists) for society globally.
In the course of the COVID-19 pandemic, scientists are facing great challenges because they have to reorient, interrupt or even cancel research and teaching. International researchers demand the active protection and support of diversity, equity and inclusion in science.
A webtool giving an overview of climate change in Europe and predicting subsequent developments was created as a joint collaboration between French, Spanish, German and Estonian researchers.
Undoubtedly, our solutions are embedded in nature but we need to find them, and more importantly learn to worship the nature. Raising awareness about respecting the nature’s bounty, conserving all biodiversity that it harborsand utilizing it for sustainable solutions is the key.
Evolutionary biologists have identified how herbicide-resistant strains of common waterhemp, an invasive weed, have emerged in fields of soy and corn in southwestern Ontario.
