Bananas (Musa spp.), including dessert and cooking types, are giant perennial monocotyledonous herbs of the order Zingiberales, a sister group to well-studied Poales, which include cereals. vital for food security in many tropical subtropical countries most popular fruit industrialized countries. The Musa domestication process started some 7,000 years ago Southeast Asia. It involved hybridizations between diverse species subspecies, fostered by human migrations, selection diploid triploid...
Xavier Argout and colleagues report the draft genome of Theobroma cacao, tropical crop that is source chocolate. The sequence assembly covers approximately 80% genome. We sequenced assembled an economically important tropical-fruit tree This corresponds to 76% estimated size contains almost all previously described genes, with 82% these genes anchored on 10 T. cacao chromosomes. Analysis this information highlighted specific expansion some gene families during evolution, for example,...
Zhong-Jian Liu, Lai-Qiang Huang, Yi-Bo Luo, Hong-Hwa Chen and Yves Van de Peer report the first genome sequence of a crassulacean acid metabolism (CAM) plant, orchid Phalaenopsis equestris. They identify genes encoding CAM pathway enzymes find that gene duplication was likely key process in evolution photosynthesis. Orchidaceae, renowned for its spectacular flowers other reproductive ecological adaptations, is one most diverse plant families. Here we present tropical epiphytic equestris,...
Oaks are an important part of our natural and cultural heritage. Not only they ubiquitous in most common landscapes1 but have also supplied human societies with invaluable services, including food shelter, since prehistoric times2. With 450 species spread throughout Asia, Europe America3, oaks constitute a critical global renewable resource. The longevity (several hundred years) probably underlies their emblematic historical importance. Such long-lived sessile organisms must persist the face...
Receptor-like kinases are well-known to play key roles in disease resistance. Among them, the Wall-associated (WAKs) have been shown be positive regulators of fungal resistance several plant species. WAK genes often transcriptionally regulated during infection but pathways involved this regulation not known. In rice, OsWAK gene family is significantly amplified compared Arabidopsis. The possibility that WAKs participate different ways basal defense has addressed. Moreover, direct requirement...
Sugarcane, the world's most harvested crop by tonnage, has shaped global history, trade and geopolitics, is currently responsible for 80% of sugar production worldwide
Abstract Plant roots have a large range of functions, including acquisition water and nutrients, as well structural support. Dissecting the genetic molecular mechanisms controlling rice root development is critical for new ideotypes that are better adapted to adverse conditions production sustainably achieved yield potential. Most knowledge regarding gene networks involved in has been accumulated model dicotyledon plant species Arabidopsis thaliana . Rice, monocotyledon species, presents...
The CLAVATA1 (CLV1) receptor kinase controls stem cell number and differentiation at the Arabidopsis shoot flower meristems. Other components of CLV1 signaling pathway include secreted putative ligand CLV3 receptor-like protein CLV2. We report evidence indicating that all intermediate strong clv1 alleles are dominant negative likely interfere with activity unknown kinase(s) have functional overlap CLV1. dominant-negative show major differences from characterized to date in animal systems,...
Root traits such as root angle and hair length influence resource acquisition particularly for immobile nutrients like phosphorus (P). Here, we attempted to modify in rice by disrupting the OsAUX1 auxin influx transporter gene an effort improve P efficiency. We show X-ray microCT imaging that is altered osaux1 mutant, causing preferential foraging top soil where normally accumulates, yet surprisingly, efficiency does not improve. Through closer investigation, reveal also promotes elongation...
Gene duplications are an important factor in plant evolution, and lineage-specific expanded (LSE) genes of particular interest. Receptor-like kinases massively land plants, leucine-rich repeat receptor-like (LRR-RLK) constitute the largest family. Based on phylogeny 7,554 LRR-RLK from 31 fully sequenced flowering genomes, complex evolutionary dynamics this family was characterized depth. We studied involvement selection during expansion among angiosperms. subgroups harbor extremely...
Leucine-Rich Repeats Receptor-Like Kinase (LRR-RLK) genes represent a large and complex gene family in plants, mainly involved development stress responses. These receptors are composed of an LRR-containing extracellular domain (ECD), transmembrane (TM) intracellular kinase (KD). To provide new perspectives on functional analyses these model non-model plant species, we performed phylogenetic analysis 8,360 LRR-RLK 31 angiosperm genomes (8 monocots 23 dicots). We identified 101 orthologous...
Abstract Rice production faces the challenge to be enhanced by 50% year 2030 meet growth of population in rice-eating countries. Whereas yield cereal crops tend reach plateaus and a is likely deeply affected climate instability resource scarcity coming decades, building rice cultivars harboring root systems that can maintain performance capturing water nutrient resources unevenly distributed major breeding target. Taking advantage gathering community biologists Global Science Partnership...
Insertional mutant databases containing Flanking Sequence Tags (FSTs) are becoming key resources for plant functional genomics. We have developed OryGenesDB (http://orygenesdb.cirad.fr/), a database dedicated to rice reverse genetics. Insertion mutants of genes catalogued by Tag (FST) information that can be readily accessed this database. Our presently contains 44166 FSTs generated most the insertional mutagenesis projects. The genome browser is based on powerful Generic Genome Browser...
Plant leucine-rich repeat receptor-like kinases (LRR-RLKs) are receptor that contain LRRs in their extracellular domain. In the last 15 years, many research groups have demonstrated major roles played by LRR-RLKs plants during almost all developmental processes throughout life of plant and defense/resistance against a large range pathogens. Recently, breakthrough has been made this field challenges dogma specificity LRR-RLKs. We analyzed ~1000 complete genomes show LRR-RK genes now...
Paleobotanical studies suggest that roots evolved at least twice independently during land plant diversification, once in lycophytes and euphyllophytes. Auxin promotes postembryonic root initiation both groups but from different cell types. In several euphyllophytes, such as Arabidopsis, rice, maize, AS2/LOB-domain (ASL/LBD) proteins act directly downstream of auxin are conserved elements necessary for initiation. It is currently unknown whether similar or genetic mechanisms We searched...
Plant root systems play a major role in anchoring and water nutrient uptake from the soil. The cone angle is an important parameter of system architecture because, combined with depth, it helps to determine volume soil explored by plant. Two genes, DRO1 SOR1, several QTLs for have been discovered last 5 years.To find other linked angle, genome-wide association mapping study was conducted on two panels 162 indica 169 japonica rice accessions genotyped sets SNP markers...
Plants are constantly exposed to a variety of biotic and abiotic stresses that reduce their fitness performance. At the molecular level, perception extracellular stimuli subsequent activation defense responses require complex interplay signaling cascades, in which protein phosphorylation plays central role. Several studies have shown some members Leucine-Rich Repeat Receptor-Like Kinase (LRR-RLK) family involved stress developmental pathways. We report here systematic analysis role this gene...
