Twilight

Twilight Twilight, the period between day and night. The duration of twilight influences the growth and flowering of plants. That, are Canadian and Belgian researchers now showing in Scientific Reports. The influence of twilight on plants was up to date not really studied. For a long time it was difficult to reproduce twilight light conditionsContinue reading “Twilight”

To mow or not to mow

To mow or not to mow Framers do rather not want toxic plants in their grass clippings that they use as feed for their animals. Now American researchers show in Scientific Reports that mowing actually contributes to the distribution of the toxic silverleaf nightshade (Solanum elaeagnifolium). When plants are stressed they turn to survival mode.Continue reading “To mow or not to mow”

Early division

Early division Cells within organisms only divide when they have a certain amount of stem cell identity. Now Dutch researchers show in Development that the PLETHORA genes are turning on this stem cell identity directly after fertilisation. To keep control over their shape, organisms tightly control which cells are allowed to divide. In general thisContinue reading “Early division”

Old clones

Old clones A group of international researchers discovered that an eelgrass colony is about 1400 years old. They managed this feat due to the developing an new age determination method for clones that they published in Nature and Ecology & Evolution. For organisms that multiply by cloning themselves it is difficult to determine their age.Continue reading “Old clones”
