Winter Survival of Grasses and Legumes in Subarctic Alaska as Related to Latitudinal Adaptation, Pre-Winter Storage of Food Reserves, and Dry-Matter Concentration in Overwintering Tissues [PDF]

, 1993
similar experiments, were to (a) compare winter hardiness in subarctic Alaska of numerous plant species and ecotypes from various latitudinal sources within most species, and (b) seek a better understanding of certain aspects of pre-winter ...

Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System

Advanced Science, EarlyView.
Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

OsGSK2‐OsTCP19 Module Integrates Nitrogen and Brassinosteroid Signaling to Regulate Nitrogen Utilization and Root Growth in Rice

Advanced Science, EarlyView.
OsGSK2‐OsTCP19 module regulating nitrate response and lateral root (LR) development. Low‐nitrate condition results in reduced BR response, accumulation of OsGSK2 and phosphorylated OsTCP19, which suppresses the expression of nitrate‐responsive genes and LR‐development genes and impairs rice growth.

Taxonomical revision of the Late Würm Sorex (Mammalia, Insectivora) remains of Hungary, for proving the presence of an alpine ecotype in the Pilisszántó Horizon [PDF]

, 2004
Fossil bone assemblages of 14 localities, ranged in the Pilisszántó Horizon (Late Würm), are stored in the collection of the Geological Museum of Hungary and Hungarian Natural History Museum.

White spruce limestone ecotypes

The Forestry Chronicle, 1974
White spruce provenances from soils with limestone parent material, and non-limestone parent material were planted on calcareous and non-calcareous soils. The limestone provenances grew the most on calcareous soils: the non-limestone provenances grew the most on non-calcareous soils. Limestone ecotypes have evolved by natural selection.

Ecotypes of the Mycobacterium tuberculosis complex [PDF]

Journal of Theoretical Biology, 2006
A phylogeny of the Mycobacterium tuberculosis complex has recently shown that the animal-adapted strains are found in a single lineage marked by the deletion of chromosomal region 9 (RD9) [Brosch et al., 2002. A new evolutionary scenario for the Mycobacterium tuberculosis complex. Proc. Natl Acad. Sci. USA 99 (6), 3684-3689].

The myth of the metabolic baseline: sleep–wake cycles undermine a foundational assumption in organismal biology

Biological Reviews, EarlyView.
ABSTRACT Basal and standard metabolic rate (BMR and SMR) are cornerstones of physiological ecology and are assumed to be relatively fixed intrinsic properties of organisms that represent the minimum energy required to sustain life. However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned

Knock-Out of the Genes Coding for the Rieske Protein and the ATP-Synthase δ-Subunit of Arabidopsis [PDF]

, 2003
In Arabidopsis, the nuclear genes PetC and AtpD code for the Rieske protein of the cytochrome b6/f (cyt b6/f) complex and the δ-subunit of the chloroplast ATP synthase (cpATPase), respectively.

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.
