Spatial and Temporal Changes in Crop Species Production Diversity in Mexico (1980–2020)

open access: yes, 2022
Crop species diversity is a key component of agroecosystem resilience, food system stability, ecosystem services production, and sustainable development. Despite its importance, quantitative understanding of crop species diversity is often lacking.

Increased experimental conditions and marker densities identified more genetic loci associated with southern and northern leaf blight resistance in maize

open access: yesScientific Reports, 2018
Southern leaf blight (SLB) and northern leaf blight (NLB) are the two major foliar diseases limiting maize production worldwide. Upon previous study with the nested association mapping (NAM) population, which consist of 5,000 recombinant inbred lines ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Potential, attainable, and current levels of global crop diversity

open access: yesEnvironmental Research Letters, 2022
High levels of crop species diversity are considered beneficial. However, increasing diversity might be difficult because of environmental constraints and the reliance on a few major crops for most food supply.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Comparison of Organic and Conventional Agriculture in the Czech Republic: A Systematic Review

open access: yesAgriculture
This systematic review aims to comprehensively examine publications that compared conventional and organic agriculture in the Czech Republic. Agriculture in the Czech Republic is unique because of considerable variability in natural and climatic ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Higher crop diversity in less diverse landscapes

open access: yes, 2023
Abstract CONTEXT: Agricultural landscapes need to be diversified for ensuring resilient agricultural production and supporting biodiversity and ecosystem services. However, the relationship between agricultural diversity and landscape diversity is largely understudied. OBJECTIVES: We aim to assess the spatial organisational relationship between

Can the Right Composition and Diversity of Farmed Species Improve Food Security Among Smallholder Farmers?

open access: yesFrontiers in Sustainable Food Systems, 2022
Food security and livelihoods among smallholder farmers in sub-Saharan Africa are often constrained by limited farm resource endowment. It can be difficult to improve resource endowment given barriers such as low land availability and the unaffordability

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
