“…L.S.Sm., Macadamia tetraphylla L.A.S.Johnson and Macadamia jansenii C.L.Gross & P.H.Weston, representing approximately 2.5 times diversity in the GS, were selected for statistical comparison. These species were considered difficult due to the presence of polyphenols and tannins in the leaf material (Čertner et al ., 2022; Gadea et al ., 2022). Information about the chromosome number, ploidy and genome size estimates are available for A. sericeus , H. sayeriana (Jordan et al ., 2015; Ramsay, 1963; Rao, 1957).…”

Flow cytometry is a technique widely applied to infer the ploidy and genome size of plant nuclei. The conventional approach of sample preparation, reliant on fresh plant material to release intact nuclei, requires protocol optimisation for application to many species. The approach often results in poor yields of nuclei, impeding the accurate measurement of genome size and confines the optimal resource allocation and efficiency in genome sequencing which relies on genome size estimation. Here, we present a novel method using frozen plant material that facilitates the release of intact nuclei for genome size estimation. Genome estimates from frozen material are similar to those from fresh material. Accurate and precise estimates can be made by complementing the fluorescence of frozen nuclei with histogram modelling and debris compensation algorithms. This method of nuclei isolation from frozen plant material for flow cytometry-based genome size estimations has special value in estimating the genome size of samples collected and frozen for use in plant genome sequencing. Plant material can be conveniently stored, resampled, and used for DNA or RNA extractions.HighlightFrozen leaf material can be used to isolate nuclei for the accurate estimation of genome size The method proved suitable for difficult samples and did not require specific optimization. The method was especially useful where plant material could not be immediately processed through flow cytometry and allowed the same sample to be used for genomes size estimation and genome sequencing.

“…Currently, only 30% of Proteaceae species have been investigated for phytochemical profiling, of which less than 10% of species have had their compounds isolated and purified. The Grevillea and Protea genera have the widest use and study [71] with 362 species in Grevillea and 112 species in Protea described in previous studies [11]. There are fewer than 400 compounds identified in the family Proteaceae, including three main categories: phenolic compounds (69%), quinones (8%), and alkaloids (13%) [71,72].…”

In recent decades, natural plant-based foods have been increasingly used to improve human health due to unhealthy modern dietary patterns, such as the consumption of foods high in sugar and fat. Many indigenous species have been used by Aboriginal peoples for their food and therapeutic properties. Thus, it is important to understand the health-enhancing bioactive profile of Australian indigenous species. The Proteaceae family, such as the genera of Protea, Macadamia, and Grevillea, have been commercially used in the horticulture and food industries. Researchers have reported some findings about Persoonia species, one of the genera in the Proteaceae family. The aim of this review was to provide an overview of the family Proteaceae and the genus Persoonia, including distribution, traditional and commercial uses, phytochemicals, bioactive properties, potential opportunities, and challenges. In this review, bioactive compounds and their properties related to the health benefits of the Proteaceae family, particularly the Persoonia genus, were reviewed for potential applications in the food industry.

Natural products isolation studies of eight endemic Tasmanian Proteaceae species – Agastachys odorata, Persoonia juniperina, Hakea megadenia, Hakea epiglottis, Orites diversifolius, Orites acicularis,Orites revolutus, and Telopea truncata – and three endemic Australian Proteaceae species Banksia serrata, Banksia praemorsa, and Banksia marginata were undertaken.Two previously unreported glycoside‐derived natural products were identified, in addition to four other tremendously rare arbutin esters. The results of this study provide further evidence consistent with the proposal that these distinctive arbutin esters represent markers that can provide valuable insights into the chemical evolution of plant species within the family Proteaceae.
