The liverwort oil body is formed by redirection of the secretory pathway

Cells, the basic unit of life, are surrounded by a limiting membrane called the plasma membrane. Inside cells, there are various membrane-bounded organelles, each of which has various and distinctive functions. How these organelles, which individually boast different functions, have been developed during evolution remains unknown. This phenomenon has fascinated many researchers. In the study […]

Groups of bacteria can work together to better protect crops and improve their growth

To further improve agricultural yields, it is helpful to identify factors […]

Flag leaves could help top off photosynthetic performance in rice

The flag leaf is the last to emerge, indicating the transition from crop growth to grain production. Photosynthesis in this leaf provides the majority of the carbohydrates needed for grain filling–so it is the most important leaf for yield potential. A team from the University of Illinois and the International Rice Research Institute (IRRI) found […]

In plants, channels set the rhythm

Like animals, plants have ‘molecular switches’ on the surface of their cells that transduce a mechanical signal into an electrical one in milliseconds. In animals, sound vibrations activate ‘molecular switches’ located in the ear. French scientists have found that in plants, rapid oscillations of stems and leaves due to wind may activate these ‘switches’ very […]

Anti-transpirant products unnecessary in cycad propagation

In his recently published research, he found the use of anti-transpirants to neither help nor… view more  Credit: University of Guam In a first-of-its-kind study within cycad horticulture literature, University of Guam researchers have found that the use of anti-transpirants […]

The puzzle of nonhost resistance: why do pathogens harm some plants but not others?

IMAGE: Ralph Panstruga & Matthew Moscou view more  Credit: Ralph Panstruga & Matthew Moscou People have puzzled for years why pathogen Phytophthora infestens causes the devastating late blight disease, source of the Irish Potato famine, on potatoes, but has no effect at all on plants like apple or cucumber. How are apple trees and cucumber plants […]
