The importance of conserving plant genetic diversity has been recognised since the 1980's, but genetic research tools for improving conservation remain largely absent from standard planning. Using an Australian case study framework of the New South Wales Government's Saving our Species program, we outline the costs and benefits associated with conducting genomic analysis within a conservation strategy to inform for example, taxonomic resolution, targeted monitoring, translocations and ex situ collections. Despite a reported sentiment that costs are prohibitive, our study identified that where genetics reports have been provided (32 to date), the cost of genetic sampling, analysis and advice is less than 10% of the total Government investment (SoS program) and will continue decreasing proportionally throughout the years as other management occurs.

Introduction: Intracellular Ca signalling regulates membrane permeabilities, enzyme activity, and gene transcription amongst other functions. Large transmembrane Ca electrochemical gradients and low diffusibility between cell compartments potentially generate short-lived, localised, high-[Ca] microdomains. The highest concentration domains likely form between closely apposed membranes, as at amphibian skeletal muscle transverse tubule-sarcoplasmic reticular (T-SR, triad) junctions.

Human craniofacial shape is highly variable yet highly heritable with numerous genetic variants interacting through multiple layers of development. Here, we hypothesize that Mendelian phenotypes represent the extremes of a phenotypic spectrum and, using achondroplasia as an example, we introduce a syndrome-informed phenotyping approach to identify genomic loci associated with achondroplasia-like facial variation in the general population. We compare three-dimensional facial scans from 43 individuals with achondroplasia and 8246 controls to calculate achondroplasia-like facial scores.

Human facial shape, while strongly heritable, involves both genetic and structural complexity, necessitating precise phenotyping for accurate assessment. Common phenotyping strategies include simplifying 3D facial features into univariate traits such as anthropometric measurements (e.g.
