Question: My nectarine and peach trees have hard pale green ball things near the base of leaves. What are they and are they harmful to my trees? Answer: How cool! I’d never heard of anything like this ...

Around 4,000 plant species from different parts of the world secrete nectar outside their flowers, such as on their stems or leaves, through secretory glands known as extrafloral nectaries. Unlike ...

Evolution is based on diversity, and sexual reproduction is key to creating a diverse population that secures competitiveness in nature. Plants had to solve a problem: they needed to find ways to ...

Premise of the study: Extrafloral nectaries (EFNs) are structures that secrete nectar and protect plants against herbivores and pathogens. In Gentianaceae, these structures have been described in ...

Flowers get all the attention when it comes to providing nectar for pollinating insects, but Tino shows another, less well-known source of nectar. They’re called extra-floral nectaries - quite a ...

Plants and the animals that eat them have evolved together in fascinating ways, creating a dynamic interplay of survival strategies. Many plants have developed physical and chemical defenses to fend ...

A recent study led by Bucknell University Professor Chris Martine, biology, the David Burpee Professor of Plant Genetics and Research, has identified and described a new species of bush tomato with a ...

Ant–plant mutualisms constitute a compelling model of coevolution, whereby plants have evolved specialised structures, notably extrafloral nectaries (EFNs), to entice ants that in turn afford ...

To make sure that flying pollinators come to flowers to pick up pollen, plants evolved special organs, the nectaries, to attract the animals. Scientists have now identified the sugar transporter that ...
