Single‐Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum

Plant Biotechnology Journal, EarlyView.
ABSTRACT B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue‐specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome maintained mainly in limited regions of meristems.

Microbial volatile compounds enhance drought resilience and productivity in CAM and C3 crops

Plant Biology, EarlyView.
Microbial volatiles EV and CAMP, derived from Bacillus spp. and Beauveria pseudobassiana associated with agaves and cacti, respectively, enhance drought resilience and productivity in Agave tequilana and tomato. Abstract Plants interact with their associated microbiota through diverse chemical cues, including microbial volatile organic compounds (mVOCs)

Floral adaptation and modular trait evolution associated with a shift from bee to hummingbird pollination

Plant Biology, EarlyView.
By comparing floral trait variation, integration and modularity in two sister species of Neotropical Costus with a pollination shift, we show that, despite pollination syndrome divergence, both species exhibit low floral variation and functional modularity, consistent with pollinator‐driven selection on traits mediating pollen transfer efficiency and ...

Medication Exposure Definitions in Perinatal Pharmacoepidemiology: Implications for Pregnancy Studies

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Exposure definitions in real‐world pregnancy studies vary across studies, data sources, treatments and outcomes, yet their impact on prevalence estimates remains unexamined. Objectives To identify the most used exposure definitions during the 1st trimester and evaluate their impact on prevalence estimates: Methods We reviewed 400 ...

Infertility and Risk of Congenital Anomalies: A Population‐Based Cohort Study

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Fertility treatments have been associated with an increased risk of congenital anomalies. Most studies have compared births conceived through fertility treatment with unassisted conceptions; consequently, these estimates reflect the combined effects of fertility treatment and the underlying infertility, potentially resulting in ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Born early, age fast: Consequences of premature birth on chronic disease and accelerated ageing

The Journal of Physiology, EarlyView.
Abstract figure legend ELGANs are exposed to several postnatal pro‐oxidant stressors, including ambient and supplemental oxygen, mechanical ventilation, infections, hyperalimentation, excessive glucocorticoids and intermittent hypoxia. Since endogenous antioxidant defences are underdeveloped, this imbalance promotes oxidative stress and inflammation ...

Hypoxia and the cytoskeleton

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the activation of hypoxia‐sensitive pathways, the influence of hypoxia and associated pathways on the cytoskeleton, and the impact of these on disease progression. Abstract A highly‐regulated and dynamic cytoskeleton is vital for functional cellular physiology and the maintenance of homeostasis.
