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

Lichen bleaching as a response to long‐term experimental warming in the High Arctic

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

Characterization of three 2-hydroxy-acid dehydrogenases in the context of a biotechnological approach to short-circuit photorespiration [PDF]

, 2010
Photorespiration results from the incorporation of oxygen into ribulose-1,5-bisphosphate due to the failure of RuBisCO to properly discriminate between oxygen and carbon dioxide.

Ecophysiological traits of grasses: resolving the effects of photosynthetic pathway and phylogeny [PDF]

, 2009
C4 photosynthesis is an important example of convergent evolution in plants, having arisen in eudicots, monocots and diatoms. Comparisons between such diverse groups are confounded by phylogenetic and ecological differences, so that only broad ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Manipulating photorespiration to increase plant productivity:recent advances and perspectives for crop improvement [PDF]

, 2016
Recycling of the 2-phosphoglycolate generated by the oxygenase reaction of Rubisco requires a complex and energy-consuming set of reactions collectively known as the photorespiratory cycle.

Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

New Phytologist, EarlyView.
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

Improved mesophyll–bundle sheath connectivity is achieved via different mechanisms in C2 vs C4 Alternanthera

New Phytologist, EarlyView.
Leaf anatomy and biochemistry of C3, C2, and C4 plants. Summary Connectivity between mesophyll (M) and bundle sheath (BS) cells must improve during the evolution of C4 photosynthesis to facilitate large metabolite fluxes between these cell types, but the trait combinations that enhance M–BS connectivity and the points at which these enhancements occur ...

Evolution of Photorespiratory Glycolate Oxidase among Archaeplastida

Plants, 2020
Photorespiration has been shown to be essential for all oxygenic phototrophs in the present-day oxygen-containing atmosphere. The strong similarity of the photorespiratory cycle in cyanobacteria and plants led to the hypothesis that oxygenic ...
