A new study has uncovered intriguing insights into the evolution of plant biology, effectively rewriting the history of how they evolved over the past billion years.

A long-lived monocarpic species of bamboo, Phyllostachys nigra var. henonis, only flowers once every 120 years before it dies. The upcoming flowering event for this species does not bode well for its continued long-term survival, as most flowers are not producing viable seeds.
An international group of scientists has issued an urgent call for coordinated action to save the iconic genus Rafflesia, which contains the world’s largest flowers. This follows a new study which found that most of the 42 species are severely threatened, yet just one of these is listed in the International Union for Conservation of Nature (IUCN)’s Red List of Threatened Species. Furthermore, over two thirds (67%) of the plants’ habitats are unprotected and at risk of destruction.
The Earth’s surface is covered by plants. They make up the majority of biomass on land and exhibit a wide range of diversity, from mosses to trees. This astounding biodiversity came into existence due to a fateful evolutionary event that happened just once: plant terrestrialization. This describes the point where one group of algae, whose modern descendants can still be studied in the lab, evolved into plants and invaded land around the world. An international group of researchers generated large scale gene expression data to investigate the molecular networks that operate in one of the closest algal relatives of land plants, a humble single-celled alga called Mesotaenium endlicherianum.
Pollen of flowering plants can be dispersed by animals, wind or even by water. In assessing pollination modes, a fundamental question is how many flowering plants are pollinated by animals. Although the question has been raised previously, an accurate estimation remains elusive.
How long can trees tolerate drought before the forest dies? Researchers can now predict which forests could survive despite future drought. Their new method links precipitation to tree growth, and it can help people decide where to put their resources as climate change affects patterns of snow and rainfall that impact the health of forests.
Researchers inoculated oilseed rape plants with a species of fungus that is known for its ability to combat pest insects. Utilising the relationship between beneficial fungi and crop plants may introduce a new era of agriculture where the plant resilience is improved and the ecological footprint of traditional/chemical pesticides is minimised.
Plant scientists team up to pinpoint the exact mechanism that controls epigenetic inheritance in plants. Their discovery could have implications for agriculture, food supplies, the environment, and our understanding of the human genome.
A new study demonstrates that one of the two branches of plant immunity was likely to have evolved early during the establishment of plants on dry land. This insight into prehistoric plant immunity may have implications for breeding more resistant plant species.
Researchers have discovered a new species of Artemisia — Artemisia qingheensisin – in China’s Xinjiang Uygur Autonomous Region.
