Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Uprooting Diversity? Peasant Farmers’ Market Engagements and the on-Farm Conservation of Crop Genetic Resources in the Guatemalan Highlands [PDF]

open access: yes
The long-term security of the global food supply is contingent upon the on-farm conservation of crop genetic diversity. Without it, food crops lack the ability to evolve in the face of new pests, emerging plant diseases, and changing environmental ...

Genetic diversity of Athabaskan Indians

open access: yesAnnals of Human Biology, 1979
If Athabaskan Indians are subdivided by linguistic group, a wide diversity in gene frequencies is disclosed. This diversity approximated that found when linguistically unrelated groups were compared. It was greater than that found for Eskimo-Aleus, even though the latter are more heterogeneous linguistically and subject to a wider variety of ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Genetic variability of cultivated cowpea in Benin assessed by random amplified polymorphic DNA [PDF]

open access: yes, 2008
Characterization of genetic diversity among cultivated cowpea [Vigna unguiculata (L.) Walp.] varieties is important to optimize the use of available genetic resources by farmers, local communities, researchers and breeders.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Detection of genetic diversity among Indian strains of _Xanthomonas campestris_ pv. _mangiferaeindicae_ using PCR-RAPD [PDF]

open access: yes, 2008
The randomly amplified polymorphic DNA (RAPD) technique was used to investigate the genetic diversity in 6 strains of _Xanthomonas campestris_ pv. _mangiferaeindicae_ (_Xcmi_), the causal pathogen of mango bacterial canker disease (MBCD).

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Genetic Diversity and Population Structure of the Invasive Oriental Fruit Fly, Bactrocera dorsalis (Diptera: Tephritidae) in Burkina Faso [PDF]

open access: yes
Bactrocera dorsalis Hendel is a highly invasive horticultural pest that is of major economic importance worldwide. In Burkina Faso, it is one of the main insect pests that affects the production and exportation of mangos.
