Wounding Leaves Produces Sweeter Organic Strawberries

By Radhika Desikan Do you like your fruit to be organically grown or conventionally grown? This has been a choice available to consumers since the first half of the 20th century in response to raised awareness about agriculture’s dependence on synthetic chemicals. With increasing scientific discoveries of novel chemicals that protect and help plants grow, there was also increased knowledge about the possible dangers of having these chemicals in food crops. This resulted in farmers growing crops without the use of agrochemicals, leading to the movement of organic farming. There…

Parasitic Plant Has Edge in Evolutionary Arms Race

By Cameron Duke (@DukeofCam) The relationship between a parasite and its host can be a contentious one. Their interests are in direct conflict with one another, so each is always trying to circumvent the other’s plan. This is often thought of as an evolutionary “arms race.” In this ongoing competition, a parasite evolves a more efficient way to prey on the host, and the host adapts in response. These successive adaptations can lead to complex life cycles and intimate species-specific relationships.  New research out of Penn State, conducted by Michael…

Genome Revelations: How Green Plants Evolved

By Jacqueline Mattos (@mattosjacq) Plants are ancestral organisms that have evolved over millions of years, leading to the broad diversity we see today. Green plants evolved from a common ancestor into approximately 450,000–500,000 species today. There are many gaps in understanding of their diversification that scientists still struggle to fill. In a recent paper published in Nature, researchers from the One Thousand Plant Transcriptomes Initiative reviewed and analyzed genomic data from 1,124 plant species and provided the most complete evolutionary relationship tree for green plants to date. Genomes, transcriptomes, and…
