The Evolutionary Origin of C Photosynthesis in the Grass Subtribe Neurachninae.

The Australian grass subtribe Neurachninae contains closely related species that use C, C, and C photosynthesis. To gain insight into the evolution of C photosynthesis in grasses, we examined leaf gas exchange, anatomy and ultrastructure, and tissue localization of Gly decarboxylase subunit P (GLDP) in nine Neurachninae species. We identified previously unrecognized variation in leaf structure and physiology within that represents varying degrees of C-C intermediacy in the Neurachninae.

Using hyperspectral imaging to determine germination of native Australian plant seeds.

We investigated the ability to accurately and non-destructively determine the germination of three native Australian tree species, Acacia cowleana Tate (Fabaceae), Banksia prionotes L.F. (Proteaceae), and Corymbia calophylla (Lindl.
