HSP90-buffered genetic variation is common in Arabidopsis thaliana
HSP90 is a protein chaperone particularly important in the maturation of a diverse set of proteins that regulate key steps in a multitude of biological processes. Alterations in HSP90 function produce altered phenotypes at low penetrance in natural populations. Previous work has shown that at least some of these phenotypes are due to genetic variation that remains phenotypically cryptic until it is revealed by the impairment of HSP90 function. Exposure of such “buffered” genetic polymorphisms can also be accomplished by environmental stress, linking the appearance of new phenotypes to defects in protein homeostasis. Should such polymorphisms be widespread, natural selection may be more effective at producing phenotypic change in suboptimal environments. In evaluating this hypothesis, a key unknown factor is the frequency with which HSP90-buffered polymorphisms occur in natural populations. Here, we present Arabidopsis thaliana populations suitable for genetic mapping that have constitutively reduced HSP90 levels. We employ quantitative genetic techniques to examine the HSP90-dependent polymorphisms affecting a host of plastic plant life-history traits. Our results demonstrate that HSP90-dependent natural variation is present at high frequencies in A. thaliana, with an expectation that at least one HSP90-dependent polymorphism will affect nearly every quantitative trait in progeny of two different wild lines. Hence, HSP90 is likely to occupy a central position in the translation of genotypic variation into phenotypic differences

How to write effective referral letters
Referral letters are the key mode of communication between GPs and hospital specialists for routine and acute management of conditions. While verbal communication skills are strongly emphasized in undergraduate training, written communication is relatively neglected. Medical students and postgraduate doctors are rarely formally taught to write referral letters; it is a skill learnt on the job through opportunistic and informal tuition and by reading referral letters written by others. Consequently, the style, content and quality of referral letters differ greatly among doctors. This article discusses professional expectations, outlines components of effective referral writing and provides a referral letter template
