May 2023 – Fieldwork in Australia
Awesome trip to Australia to collect grasses from the subtribe Anthistiriinae (Andropogoneae, Poaceae) for a recent national Taxonomy Research Grant Program (NTRGP) in collarboartion with Dr Richard Jobson (National Herbarium of New South Wales). Great trip, although i will be happy to not see any snakes for a while!

Leaf anatomy explains the strength of C4 activity within the grass species Alloteropsis semialata
Ahmed's first paper from his PhD published in Plant, Cell and Environment! Ahmed links anatomical variation and C4 activity. Increased investment in bundle sheath boosts the strength of the intercellular C4 pump and shifts the balance of carbon acquisition towards the C4 cycle. Carbon isotope ratios indicating a stronger C4 pathway are associated with warmer, drier environments, suggesting that incremental anatomical alterations can lead to the emergence of C4 physiology during local adaptation within metapopulations.

Lara has published a fantastic review looking at the mechanisms underpinning lateral gene trasnfer between grasses in the journal Plants, People and Plannet. In this review, Lara shows that transformation techniques used to genetically modify organisms could occur in the wild and be responsible for the frequently observed grass-to-grass LGTs. The distinction between natural evolutionary processes and genetic engineering might be arbitrary, and its validity will be further debated as agricultural biotechnology becomes more widely used and examples of “natural genetic engineering” through LGT increase.
