Integrating developmental and macroevolutionary approaches reveals a staminodial origin of all alternisepalous organs in Caryophyllaceae

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The identity of sterile floral organs in second‐whorl, alternisepalous positions within Caryophyllaceae remains contentious, having been described as staminodes, “petaloids,” or petals homologous with those of other Pentapetalae. Limited ingroup and outgroup sampling and floral developmental data and inadequate phylogenetic comparative

The Homozygous p.(Arg215Ter) Variant in XRCC2 Is Associated With Atypical Fanconi Anemia Without Major Hematological Abnormalities in Childhood

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Fanconi Anemia (FA) is the most frequent inherited bone marrow failure syndrome. A role for the XRCC2 gene in FA was suspected in 2012 and confirmed in 2016, but only two affected individuals have been described thus far, and no long‐term follow‐up is available.

Defining Features of Gabriele‐de Vries Syndrome in Adults: A Case Report and Literature Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Gabriele‐de Vries syndrome (GADEVS) is a neurodevelopmental disorder caused by heterozygous pathogenic variants in the YY1 gene. Like most rare genetic syndromes, the adult manifestations of GADEVS remain poorly defined. Here, we describe the oldest patient reported to date with GADEVS—a 63‐year‐old woman with a c.1177_1179del YY1 variant ...

New Water Oxidation Mechanism in Photosystem II Resolves Major Experimental Controversies

open access: yesAngewandte Chemie, EarlyView.
In Photosystem II Oxygen Evolving Complex, we discovered the O3‐O6 peroxide at lower energy. Assignment of the O3 ligated by histidine (His337) as a slow exchanging substrate and its coupling with O6 give the O─O bond formation mechanism most consistent with all currently available experimental data. Proposal shows how protein environment can steer the
