Range unit root tests [PDF]

open access: yes, 2003
Since the seminal paper by Dickey and Fuller in 1979, unit-root tests have conditioned the standard approaches to analyse time series with strong serial dependence, the focus being placed in the detection of eventual unit roots in an autorregresive model

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.

Growth, water relations and physiological processes of starfruit (Averrhoa carambola L) plants under root growth restriction [PDF]

open access: yes, 1996
Starfruit (Averrhoa carambola L., Clone B17) plants were grown in two levels of root zone volume (3.36 m3 or 0.68 m3) and two levels of water availability (well watered or 30% of field capacity).

Localized Expression of Cathepsin B-like Sequences from Root Nodules of Pea (Pisum sativum)

open access: yesMolecular Plant-Microbe Interactions, 2000
Cathepsin B is an ancient family of eukaryotic cysteine proteases. We describe PsCat1, a plant cathepsin B-like transcript, identified as an expressed sequence in Rhizobium-induced, nitrogen-fixing root nodules of pea.

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 ...

Effects of root restriction on growth and associated cytokinin levels in cotton (Gossypium hirsutum)

open access: yes, 2010
Root restriction experiments on cotton plants were conducted under conditions where water and nitrogen supplies were not limiting. Xylem sap and leaf tissues were obtained before significant biomass reduction as a result of root restriction.

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.

The development impact of genetic use restriction technologies: a forecast based on the hybrid crop experience [PDF]

open access: yes, 2003
Advances in biotechnology have made available gene-manipulation techniques that enable the protection of genetic material from unauthorized use and the prevention of self-supply of commercial seeds by farmers—in order to allow enhanced appropriation of ...

Structural and hydraulic changes in grape shoot xylem under different root zone volumes

open access: yesOENO One
Root zone restriction, an efficient cultivation technique in grape production, alters the morphology and function of both the root system and the above-ground parts.
