Phosphorus nutrition in Proteaceae and beyond
Nature Plants, 2015Proteaceae in southwestern Australia have evolved on some of the most phosphorus-impoverished soils in the world. They exhibit a range of traits that allow them to both acquire and utilize phosphorus highly efficiently. This is in stark contrast with many model plants such as Arabidopsis thaliana and crop species, which evolved on soils where nitrogen ...

Cyanogenesis in the proteaceae
Phytochemistry, 1989Abstract Living material from 155 species of Proteaceae were tested for cyanogenesis, and 44 species were found to be cyanogenic. The cyanogenic glycosides dhurrin and/or proteacin were identified in eight species.

The sources of evidence bearing on the evolution of the Proteaceae are outlined. New cytological data are presented for Embothrium (South American), Beauprea (New Caledonian), and 15 Australian genera which are mostly tropical or subtropical and with morphological characters considered primitive.

Climate drives vein anatomy in Proteaceae
American Journal of Botany, 2013• Premise of study: The mechanisms by which plants tolerate water deficit are only just becoming clear. One key factor in drought tolerance is the ability to maintain the capacity to conduct water through the leaves in conditions of water stress. Recent work has shown that a simple feature of the leaf xylem cells, the cube of the thickness of cell ...

The vascular anatomy of the flower shows that the perianth inMacadamia ternifolia F. Muell. is the whorl of sepals, while the corolla has completely disappeared. Thus a dichalmydeous ancestry is suggested for the Proteaceae. The adnation of the stamens to the perianth is of recent origin.

SCAB DISEASE OF PROTEACEAE – A REVIEW
Acta Horticulturae, 2001Elsinoe spp. cause scab disease of South African Proteaceae such as Leucadendron, Leucospermum, Mimetes, Protea and Serruria, as well as on the Australian genus Banksia. In South Africa, this disease has been observed on Leucadendron, Leucospermum, Protea and Serruria. In Australia, scab disease occurs on all the genera cited above.

Developments in understanding of the Proteaceae since 1963 are briefly reviewed and discussed in relation to morphological interpretation, DNA studies, phytogeography and phylogeny. Some of the outstanding questions are highlighted. Starting Point More than 30 years ago, Barbara Briggs and I (Johnson and Briggs 1963)
