Sex in plants requires thrust

In a paper to be published in the September 2018 issue of TECHNOLOGY, the thrust produced by the microscopic organ delivering sperm cells in plants has now been measured using microfluidic technology. A team of nano and microsystems ...

Hydrogen peroxide assists sexual reproduction in spruce

Plant physiologists from MSU have proved for the first time that dangerous reactive oxygen species that are often considered by-products of energy generation in cells are required by conifers to fertilize egg cells. Experiments ...

Unlocking the mystery of pollen tube guidance

Fertilization in flowering plants occurs by the delivery of sperm cells to the ovule by the precise growth of pollen tubes from pollen. Pollen tube guidance plays a crucial role in controlling the growth of pollen tubes and ...

How plants form their seeds

Vegetable, fruit, or grain – the majority of our food results from plant reproduction. Researchers at UZH have now discovered the key to how plants regulate pollen growth and seed formation. In addition to seed formation, ...

No need to fertilize, for increase in seed size”

Plant biologists at ITbM have made a key discovery that the contents in pollen tubes alone can increase the size of seeds, without the need for fertilization. This finding may be useful in developing crops, which can develop ...

Cell fusion discovery could improve agricultural production

An international research team has observed cell fusion in flowering plants for the first time in more than a century. The discovery demystifies how plants prevent the attraction of excessive pollen tubes after a successful ...
