Protein aggregation in plant mitochondria lacking Lon1 inhibits translation and induces unfolded protein responses

Ce Song, Yuanyuan Li, Mengmeng Yang, Tiantian Li, więcej

Plant, Cell & Environment > 47 > 11 > 4383 - 4397

Loss of Lon1 led to stunted plant growth and accumulation of nuclear‐encoded mitochondrial proteins including Lon1 substrates. However, an in‐depth label‐free proteomics quantification of mitochondrial proteins in lon1 revealed that the majority of mitochondrial‐encoded proteins decreased in abundance. Additionally, we found that lon1 mutants contained protein aggregates in the mitochondrial that...

Inequality in an Equal Society

Laura A. Harvey, Jochen O. Mierau, James Rockey

Oxford Bulletin of Economics and Statistics > 86 > 4 > 871 - 904

A society in which everybody of a given age has the same income will exhibit substantial income and wealth inequality. We use this idea to empirically quantify inter‐cohort inequality – the share of observed inequality attributable to life‐cycle profiles of income and wealth – using data on male earnings and household wealth. We document that recent increases in income and wealth inequality in the...

Sarah A. Knutie, Cynthia N. Webster, Grace J. Vaziri, Lauren Albert, więcej

Global Change Biology > 30 > 1 > n/a - n/a

Human activity changes multiple factors in the environment, which can have positive or negative synergistic effects on organisms. However, few studies have explored the causal effects of multiple anthropogenic factors, such as urbanization and invasive species, on animals and the mechanisms that mediate these interactions. This study examines the influence of urbanization on the detrimental effect...

Clara E. Castaños, Mary C. Boyce, Tiffane Bates, A. Harvey Millar, więcej

Insect Molecular Biology > 32 > 6 > 658 - 675

Honey bee nutritional health depends on nectar and pollen, which provide the main source of carbohydrates, proteins and lipids to individual bees. During malnutrition, insect metabolism accesses fat body reserves. However, this process in bees and its repercussions at the colony level are poorly understood. Using untargeted lipidomics and gene expression analysis, we examined the effects of different...

Sibling cannibalism in the false widow spider is dependent on spiderling density and the reliable availability of fresh prey

Jeffrey A. Harvey, Robin Steegh, Yuting Dong, Rieta Gols

Ethology > 129 > 11 > 630 - 639

Adult female spiders lay batches of eggs in silken egg sacs, and after hatching, the spiderlings live for transient periods in their mother's web before dispersing. Sibling cannibalism is frequently observed among spiderlings of many species under conditions of food deprivation. Here, we conducted assays in small Petri dishes with different densities of newly hatched (second instar) spiderlings of...

Enhancing crop yields through improvements in the efficiency of photosynthesis and respiration

Andres Garcia, Oorbessy Gaju, Andrew F. Bowerman, Sally A. Buck, więcej

New Phytologist > 237 > 1 > 60 - 77

The rate with which crop yields per hectare increase each year is plateauing at the same time that human population growth and other factors increase food demand. Increasing yield potential (

Y_{p}

) of crops is vital to address these challenges. In this review, we explore a component of

Y_{p}

that has yet to be optimised – that being improvements in the efficiency with which light energy is converted into...

Plant quantity affects development and reproduction of a gregarious butterfly more than plant quality

Rieta Gols, Luuk Croijmans, Marcel Dicke, Joop J. A. Loon, więcej

Entomologia Experimentalis et Applicata > 170 > 8 > 646 - 655

The larvae of insect herbivores feed on plants that may vary nutritionally (qualitatively and/or quantitatively) over the course of insect development. Plant quality may change in response to interactions with the biotic environment that in turn may affect development and biomass of the insects feeding on these plants. However, the larvae of many gregariously feeding herbivores feed on comparatively...
