A Model for the Development of the Rhizobial and Arbuscular Mycorrhizal Symbioses in Legumes and Its Use to Understand the Roles of Ethylene in the Establishment of these two Symbioses [PDF]

open access: yes, 2002
We propose a model depicting the development of nodulation and arbuscular mycorrhizae. Both processes are dissected into many steps, using Pisum sativum L. nodulation mutants as a guideline. For nodulation, we distinguish two main developmental programs,

Antibody Catalysis of Pericyclic Reactions. [PDF]

open access: yesActa Chemica Scandinavica, 1996
In an effort to increase our insight into the catalysis of pericyclic reactions we have initiated a detailed study of an antibody that catalyzes an oxy-Cope rearrangement. We have determined the stereochemistry of the antibody-catalyzed reaction, and experiments are in progress to determine the conformation of the substrate bound in the antibody ...

Synthetic Raphanobrassica Genome Reveals Functional and Evolutionary Insights Into Clubroot Resistance Genes on Chromosome R5

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Clubroot, a severe soil‐borne disease caused by Plasmodiophora brassicae, poses a severe threat to global production of Brassicaceae oilseed crops and vegetables. To date, there has been a serious lack of clubroot‐resistant germplasms in Brassica napus (AACC), necessitating the urgent development of novel disease‐resistant germplasm.

Plasticity of Lateral Root Branching in Maize

open access: yesFrontiers in Plant Science, 2019
Extensively branched root systems can efficiently capture soil resources by increasing their absorbing surface in soil. Lateral roots are the roots formed from pericycle cells of other roots that can be of any type.

Enhanced CO2 Coordinates the Spatial Recruitment of Diazotrophs in Rice Via Root Development

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Understanding the reciprocal interaction between root development and coadapted beneficial microbes in response to elevated CO2 (eCO2) will facilitate the identification of nutrient‐efficient cultivars for sustainable agriculture. Here, systematic morphological, anatomical, chemical and gene expression assays performed under low‐nitrogen ...

Parsimonious Model of Vascular Patterning Links Transverse Hormone Fluxes to Lateral Root Initiation: Auxin Leads the Way, while Cytokinin Levels Out.

open access: yesPLoS Computational Biology, 2015
An auxin maximum is positioned along the xylem axis of the Arabidopsis root tip. The pattern depends on mutual feedback between auxin and cytokinins mediated by the PIN class of auxin efflux transporters and AHP6, an inhibitor of cytokinin signalling ...

Endocytic trafficking induces lateral root founder cell specification in Arabidopsis thaliana in a process distinct from the auxin-induced pathway

open access: yesFrontiers in Plant Science, 2023
Plants can modify their body structure, such as their root architecture, post-embryonically. For example, Arabidopsis thaliana can develop lateral roots as part of an endogenous program or in response to biotic and abiotic stimuli.

Expanding the repertoire of secretory peptides controlling root development with comparative genome analysis and functional assays [PDF]

open access: yes, 2015
Plant genomes encode numerous small secretory peptides (SSPs) whose functions have yet to be explored. Based on structural features that characterize SSP families known to take part in postembryonic development, this comparative genome analysis resulted ...

New Integrative Vectors Increase Agrobacterium rhizogenes Transformation and Help Characterise Roles for Soybean GmTML Gene Family Members

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Hairy‐root transformation is widely used to generate transgenic plant roots for genetic functional characterisation studies. However, transformation efficiency can be limited, largely due to the use of binary vectors. Here, we report on the development of novel integrative vectors that significantly increase the transformation efficiency of ...
