Armillaria root rot

, 1999
Armillaria root rot, also known as the honey toadstool or bootlace fungus, is a widespread and often destructive disease that can affect an extremely wide range of plants. Overseas, the disease is reported to be caused by Armillaria mellea. In Australia,

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Root growth and root respiration of a perennial grassland subjected to future climate change and extreme event

, 2012
Future climate scenarios suggest not only an increase in atmospheric CO2 concentration and air temperature, but also more frequent and severe extremes events, such as summer heat wave and severe drought.

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Testing for unit roots and the impact of quadratic trends, with an application to relative primary commodity prices [PDF]

In practice a degree of uncertainty will always exist concerning what specification to adopt for the deterministic trend function when running unit root tests.

Threshold stochastic unit root models [PDF]

, 2002
This paper introduces a new class of stochastic unit root (STUR) processes, where the randomness of the autorregresive unit root is driven by a threshold variable.

Assessment of the physiological potential of super sweet corn seeds

Journal of Seed Science
The assessment of physiological potential is essential in seed quality control programs. This study compared the sensitivity of different procedures for evaluating super sweet corn seed vigor, focusing on the primary root protrusion test.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

COMMODITY PRICES AND UNIT ROOT TESTS [PDF]

Endogenous variables in structural models of agricultural commodity markets are typically treated as stationary. Yet, tests for unit roots have rather frequently implied that commodity prices are not stationary. This seeming inconsistency is investigated
