Abstract
We argue that extending this formalised concept of importance to other aspects of ecology would be beneficial. We discuss approaches for measuring importance, and provide examples where explicit acknowledgement of this simple concept might promote understanding and resolve debate....

Abstract
The review analyses data on physiological and biochemical influence of rhizospheric and endophytic microorganisms promoting plant growth (PGPR-plant growth promoting rhizobacteria) on induced resistance of plants and the possibility of its use in plant cultivation to protect crops from pathogens and...

Abstract
P-type ATPases are a superfamily of membrane proteins involved in many physiological processes that are fundamental for all living organisms. Using ATP, they can transport a variety of ions and other substances across all types of cell membranes against a concentration electrochemica...

Abstract
We report that both SAR Deficient 1 (SARD1) and CBP60g are key regulators for ICS1 induction and SA synthesis. Whereas knocking out SARD1 compromises basal resistance and SAR, overexpression of SARD1 constitutively activates defense responses. In the sard1-1 cbp60g-1 double mutant, pathogen-induced...

Abstract
Symbiosis has long been associated with saltational evolutionary change in contradistinction to gradual Darwinian evolution based on gene mutations and recombination between individuals of a species, as well as with super-organismal views of the individual in contrast to the classical one-genome: on...

Theory in Biosciences (129)2-3 2010
Abstract
When new entities are formed by the integration of individual organisms, these new entities possess characteristics which go beyond the sum of the individual properties of each element of the association, resulting in the development of new attributes and capacities as an integrated whole. In this p...

Abstract
We address newly emerging questions, including the potential roles of different PYR/RCAR isoforms, and the significance of ABA-induced versus constitutive PYR/RCAR-PP2C interactions. We also consider how the PYR/RCAR-PP2C-SnRK2 pathway interfaces with ABA-dependent gene expression, ion channel regul...

Abstract
We used a theoretical approach to show that the network architecture favoring stability fundamentally differs between trophic and mutualistic networks. A highly connected and nested architecture promotes community stability in mutualistic networks, whereas the stability of trophic networks is enhanc...

Abstract
Plants are under constant attack from insects, microbes, and other physical assaults that damage or remove body parts. Regeneration is one common strategy among plants to repair their body plan. How do organisms that are proficient at regeneration adapt their developmental programs for repatterning...

We formulate a continuum model to describe the origin of orientational order in such confined arrays of dynamical microtubules.

Along the evolutionary path from single cells to multicellular organisms with a central nervous system are species of intermediate complexity that move in ways suggesting high-level coordination, yet have none. Instead, organisms of this type possess many autonomous cells endowed with programs that...

We characterized a pex7 missense mutation, pex7-2, that disrupts both PEX7 cargo binding and PEX7-PEX5 interactions in yeast, as well as PEX7 protein accumulation in plants. We examined localization of peroxisomally targeted green fluorescent protein derivatives in light-grown pex7 mutants and obser...

Abstract
Flowering plants have evolved to be a predominant life form on earth. A common principle of flowering plants and probably one of the main reasons for their evolutionary success is the rapid development of an embryo next to a supporting tissue called the endosperm. The embryo and the endosperm are pr...

Abstract
Phosphoinositides play an important role in both abiotic and biotic signalling in plants. The signalling cascade may include the production of second messengers by hydrolysis of PtdIns(4,5)P(2). However, increasingly, PtdIns(4,5)P(2) itself is shown to mediate signalling by regulating target protein...

Redox-regulation of protein import into chloroplasts and mitochondria: similarities and differences.
Abstract
Redox signals play important roles in many developmental and metabolic processes, in particular in chloroplasts and mitochondria. Furthermore, redox reactions are crucial for protein folding via the formation of inter- or intramolecular disulfide bridges. Recently, redox signals were described to be...

This essay considers Charles Darwin's late work, "Cross- and Self-Fertilization of Plants," locating it in the overall context of Darwin's thought and ideas. It is shown how it is part of a long-term interest in the purpose of sexuality, and how it complements Darwin's earlier book on the fertilizat...

The role of movement in plants was unrecognised for a long time, due to the relative slowness of such movements by comparison with those of active animals such as insects and vertebrates, and to the difficulty with which they are distinguished from mere growth processes. Given this, the pioneer work...

Small RNAs can silence transposons at transcriptional or post-transcriptional level. Newly identified small RNAs (e.g., piRNAs and endo-siRNAs) can repress the activity of transposons. Drosophila piRNAs, mouse piRNAs, mouse endo-siRNAs, and their related proteins are expressed primarily within the g...
