Plants light up your life (and night…)
Shuting Liu et al. (2025) explore the potential of engineered luminescent plants, specifically Echeveria ‘Mebina’. Injected with phosphorescent particles, these plants can absorb sunlight and emit light in various colors. While promising for sustainable lighting, challenges include labour-intensive production and the impact on plant physiology, limiting widespread application.

Rare earths: Botany meets geopolitics
The post discusses He et al., 2025’s work with Blechnum orientale, a fern that accumulates rare earth elements (REEs), in particular the mineral monazite. This discovery raises important questions about plants being a sustainable source for REEs. The post also provides background to REEs, and doesn’t ignore their geopolitical significance.

A botanical conundrum solved (sort of…)
The post follows-up on a previous post that considered how much of the plant’s photosynthesis is used in root mucilage production. In particular it discusses the challenges in verifying % claims from Wikipedia and McNear Jr. Mr P Cuttings emphasises careful source citation and acknowledges that the puzzle remains unresolved.

A botanical conundrum: HELP, please!
The post discusses the substantial – but source-substantiated – amount of energy plants use secreting root mucilage, estimated at 10-40% of their photosynthesized carbon. Mr P Cuttings expresses scepticism about these high figures, noting lower estimates from earlier studies. To clarify this discrepancy, a full copy of Newman’s 1985 article…

The domestication of people by plants…
Robert N. Spengler III’s “Nature’s greatest success” challenges the traditional view of agriculture’s origins, arguing that domestication was not a conscious act by humans but rather an inevitable outcome of plants’ evolution. He emphasises the partnership between plants and people, prompting critical thinking about our agricultural history and the role…
