PLANTS, PEOPLE, PLANET, EarlyView.Early modern herbaria house important and useful data on historic environments. However, their contents are often inhospitable to scientific use. Despite this challenge, once their contents have been deciphered, such specimens present novel research opportunities.

A THEORY OF ANGIOSPERM EVOLUTION [PDF]
Evolution, 1952 The Cretaceous period, which was transitional from the Mesozoic to the Cenozoic era, is well represented by a succession of fossil floras from both hemispheres. These floras record a change from an Early Cretaceous world dominated by typically Jurassic ferns and gymnosperms, to a Middle Cretaceous landscape in which the angiosperms had become ...

Gene turnover in the common ancestor of all C4 grasses
PLANTS, PEOPLE, PLANET, EarlyView.Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Genome duplication and the origin of angiosperms
, 2005 Despite intensive research, little is known about the origin of the angiosperms and their rise to ecological dominance during the Early Cretaceous. Based on whole-genome analyses of Arabidopsis thaliana, there is compelling evidence that angiosperms ...

The most threatened plants receive the least scientific attention
PLANTS, PEOPLE, PLANET, EarlyView.Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal

PLANTS, PEOPLE, PLANET, EarlyView.Traditional fishing with plant‐based piscicides is a global practice in decline, facing increasing restrictions. We investigated the chemical diversity of endemic Wikstroemia species historically used to stun or poison fish in Hawaiʻi. Using 1‐H‐NMR, principal component analysis, targeted HPLC, and target‐capture sequencing, we characterized compounds ...

Diversification of myco-heterotrophic angiosperms: evidence from Burmanniaceae. [PDF]
, 2008 Background - Myco-heterotrophy evolved independently several times during angiosperm evolution. Although many species of myco-heterotrophic plants are highly endemic and long-distance dispersal seems unlikely, some genera are widely dispersed and have ...
