Characterising ecological interaction networks to support risk assessment in classical biological control of weeds
A key element in weed biological control is the selection of a biological control agent that minimizes the risks of non-target attack and indirect effects on the recipient community. Network ecology is a promising approach that could help decipher tritrophic interactions in both the native and the invaded ranges, to complement quarantine-based host...
Analysis of the Rdr1 gene family in different Rosaceae genomes reveals an origin of an R-gene cluster after the split of...
The Rdr1 gene confers resistance to black spot in roses and belongs to a large TNL gene family, which is organized in two major clusters at the distal end of chromosome 1. We used the recently available chromosome scale assemblies for the R. chinensis ‘Old Blush’ genome, re-sequencing data for nine rose species and genome data for Fragaria, Rubus, ...
Redox-mediated kick-start of mitochondrial energy metabolism drives resource-efficient seed germination
...
Seeds preserve a far developed plant embryo in a quiescent state. Seed metabolism relies on stored resources and is reactivated to drive germination when the external conditions are favorable. Since the switchover from quiescence to reactivation provides a remarkable case of a cell physiological transition we investigated the earliest events in ene...
Genome ancestry mosaics reveal multiple and cryptic contributors to cultivated banana
...
Hybridizations between closely related species commonly occur in the domestication process of many crops. Banana cultivars are derived from such hybridizations between species and subspecies of the Musa genus that have diverged in various tropical Southeast Asian regions and archipelagos. Among the diploid and triploid hybrids generated, those with...
Dissecting the control of shoot development in grapevine: genetics and genomics identify potential regulators
Roles of SlETR7, a newly discovered ethylene receptor, in tomato plant and fruit development
Ethylene regulates many aspects of plant growth and development. It is perceived by a family of ethylene receptors(ETRs) that have been well described. However, a full understanding of ETR function is complicated by functionalredundancy between the receptor isoforms. Here, we characterize a new ETR, SlETR7, that was revealed by tomatogenome sequenc...
Zucchini vein clearing disease is caused by several lineages within Pseudomonas syringae species complex.
Zucchini (Cucurbita pepo) is worldwide affected by Pseudomonas syringae inducing vein clearing, stunting and necroses during plantlet development. A collection of 58 P. syringae strains isolated from diseased zucchini plantlets was characterized by multilocus sequence analysis (MLSA). A subset of 23 strains responsible for vein clearing of zucchini...
Soil microbiota influences clubroot disease by modulating Plasmodiophora brassicae and Brassica napus transcriptomes
The contribution of surrounding plant microbiota to disease development has led to the postulation of the ‘pathobiome’ concept, which represents the interaction between the pathogen, the host-plant, and the associated biotic microbial community, resulting or not in plant disease. The structure, composition and assembly of different plant-associated...
