In cereals, the root system is mainly composed of postembryonic shoot borne roots, named crown roots. The CROWN ROOTLESS1 (CRL1) transcription factor belonging to the ASYMMETRIC LEAVES2‐LIKE/LATERAL ORGAN BOUNDARIES DOMAIN (ASL/LBD) family is a key regulator of crown root initiation in rice. Here, we show that CRL1 can bind, both in vitro and in vi...
Crown roots constitute the main part of the rice root system. Several key genes involved in crown root initiation and development have been identified by functional genomics approaches. Nevertheless, these approaches are impaired by functional redundancy and mutant lethality. To overcome these limitations, organ targeted transcriptome analysis can...
Background: Due to their sessile life style, plant survival is dependent on the ability to build up fast and highly adapted responses to environmental stresses by modulating defense response and organ growth. The phytohormone jasmonate plays an essential role in regulating these plant responses to stress. Results: To assess variation of plant gr...
Crown roots (CRs) are essential components of the rice root system. Several genes involved in CR initiation or development have been indentified but our knowledge about how they organize to form a gene regulatory network (GRN) is still limited. To characterize the regulatory cascades acting during CR formation, we used a systems biology approach to...
Genetics and molecular biology have contributed to the development of rationalized plant breeding programs. Recent developments in both high-throughput experimental analyses of biological systems and in silico data processing offer the possibility to address the whole gene regulatory network (GRN) controlling a given trait. GRN models can be applie...
Introduction: The molecular mechanisms controlling crown root formation is not well understood. The crown root less 1 (crl1) mutant is devoid of crown root. The CRL1 gene encodes a plant specific LBD transcription factor. In order to identify CRL1 target genes, a transcriptomic study was carried out using the inducible expression of CRL1 in the crl...
Despite recent sequencing efforts, local genetic resources remain underexploited, even though they carry alleles that can bring agronomic benefits. Taking advantage of the recent genotyping with 22,000 single-nucleotide polymorphism markers of a core collection of 180 Vietnamese rice varieties originating from provinces from North to South Vietnam...

Bananas (Musa spp.) are the fourth most important staple food, concerning about 400 million people. With a world production estimated to 107 million tons in 2011, bananas make up the largest production of fruits, with 15% being exported. However, export-grade dessert type bananas currently rely on an intensive monovarietal monoculture, centered on...
