Identifying leaf anatomy and metabolic regulators that underpin C4 photosynthesis in Alloteropsis semialata

This study identifies genomic regions associated with C4 photosynthesis traits in Alloteropsis semialata using GWAS, highlighting key regulators of the C4 cycle and leaf anatomy.

Variation in the rate lateral gene transfers accumulate in a grass lineage

This study quantifies the rate and dynamics of lateral gene transfer (LGT) in grasses, showing high turnover and its role in generating genetic variation.

Upregulation of C4 characteristics does not consistently improve photosynthetic performance in intraspecific hybrids of a grass

The paper examines whether upregulating C4 characteristics in grass hybrids improves photosynthetic performance, finding that it depends on coordinated anatomical and biochemical changes.

Hybridisation boosts dispersal of two contrasted ecotypes in a grass species

The paper investigates hybridisation in Alloteropsis angusta, showing it facilitates the dispersal of ecotypes across Africa by enabling nuclear genome exchange via pollen and subsequent habitat-driven allele sorting.

Physiological diversity enhanced by recurrent divergence and secondary gene flow within a grass species

The paper traces the evolutionary history of photosynthetic traits in Alloteropsis semialata, showing how secondary gene flow and divergence contributed to physiological diversity.

Widespread lateral gene transfer among grasses

The paper identifies widespread lateral gene transfer among grasses, showing that it occurs across the entire family and is influenced by both opportunity and compatibility factors.

Phylogenomics supports a Cenozoic rediversification of the "living fossil" Isoetes

The paper uses genomic data and fossil records to date the origin of extant Isoetes species, finding their diversification occurred in the mid-Paleogene, not the Triassic.
