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…

Leaf Age Matters for Plant Survival

By Radhika Desikan Does age really matter? For us humans, age seems to be a very sensitive issue relevant to how we live our lives. And while it also matters to plants, it does so at a different level. Some of our tissues, like skin, have cells that are constantly dividing (to replace dead cells) and therefore differ in age, but what defines our age as an organism is not the life span of individual cells in our body, but rather the length of time that has passed since our…

Whenever something captivates my imagination (or optic nerves) I want to learn…
