Complete genome sequencing of Bacillus cabrialesii TE3^T: A plant growth-promoting and biological control agent isolated from wheat (Triticum turgidum subsp. durum) in the Yaqui Valley.

ABSTRACT: Bacillus cabrialesii TE3^T is a strictly aerobic and Gram-stain-positive plant growth-promoting bacterium, motile and catalase-positive. In addition, strain TE3^T was also recently described as a biological control agent. Here, we present the complete circularized genome of this type strain, as well as a whole genome analysis identifying genes of agricultural interest. Thus, a hybrid assembly method was performed using short-read sequencing through the Illumina MiSeq platform, and long-read sequencing through the MinION sequencing technology by Oxford Nanopore Technology (ONT). This assembly method showed a closed circular chromosome of 4,125,766 bp and 44.2% G + C content. The strain TE3^T genome annotation, based on the RAST platform, presented 4,282 Coding DNA sequences (CDS) distributed in 335 subsystems, from which 4 CDS are related to the promotion of plant growth and 28 CDS to biological control. Also, Prokka (Rapid Prokaryotic Genome Annotation) predicted a total of 119 RNAs composed of 87 tRNAs, 31 rRNA, and 1 tmRNA; and the PGAP (Prokaryotic Genome Annotation Pipeline) predicted a total of 4,212 genes (3,991 CDS). Additionally, seven putative biosynthetic gene clusters were identified by antiSMASH, such as Fengycin, Bacilysin, Subtilosin A, Bacillibactin, Bacillaene, Surfactin, and Rizocticin A, which are related to antimicrobial and antifungal properties, whose gene presence was further supported by the Prokaryotic Genome Annotation Pipeline (PGAP) annotation. Thus, the complete genome of Bacillus cabrialesii TE3^T showed promising bioactivities for the use of this type strain to bioformulate bacterial inoculants for sustainable agriculture.

Project description:BackgroundTunisia is considered a secondary center of diversification of durum wheat and has a large number of abandoned old local landraces. An accurate investigation and characterization of the morphological and genetic features of these landraces would allow their rehabilitation and utilization in wheat breeding programs. Here, we investigated a diverse collection of 304 local accessions of durum wheat collected from five regions and three climate stages of central and southern Tunisia.ResultsDurum wheat accessions were morphologically characterized using 12 spike- and grain-related traits. A mean Shannon-Weaver index (H') of 0.80 was obtained, indicating high level of polymorphism among accessions. Based on these traits, 11 local landraces including Mahmoudi, Azizi, Jneh Khotifa, Mekki, Biskri, Taganrog, Biada, Badri, Richi, Roussia and Souri were identified. Spike length (H' = 0.98), spike shape (H' = 0.86), grain size (H' = 0.94), grain shape (H' = 0.87) and grain color (H' = 0.86) were the most polymorphic morphological traits. The genetic diversity of these accessions was assessed using 10 simple sequence repeat (SSR) markers, with a polymorphic information content (PIC) of 0.69. Levels of genetic diversity were generally high (I = 0.62; He = 0.35). In addition, population structure analysis revealed 11 genetic groups, which were significantly correlated with the morphological characterization. Analysis of molecular variance (AMOVA) showed high genetic variation within regions (81%) and within genetic groups (41%), reflecting a considerable amount of admixture between landraces. The moderate (19%) and high (59%) levels of genetic variation detected among regions and among genetic groups, respectively, highlighted the selection practices of farmers. Furthermore, Mahmoudi accessions showed significant variation in spike density between central Tunisia (compact spikes) and southern Tunisia (loose spikes with open glume), may indicate an adaptation to high temperature in the south.ConclusionOverall, this study demonstrates the genetic richness of local durum wheat germplasm for better in situ and ex situ conservation and for the subsequent use of these accessions in wheat breeding programs.
