Project description:Potassium (K+) is a crucial macronutrient in high biomass plants, especially in banana.we comparatively studyed the phenotypic traits and transcriptomic profiles of banana leaves and roots between low potassium group (LK) and normal-potassium group (NK). In our study, the K+ content and biomass index of banana seedling were all significantly decreased under the stress of low potassium group. Moreover, thirty differentially expressed genes (DEGs) related to potassium transport and uptake and transcription factors were analyzed deeply. DEGs about ABC transporters, protein kinases and ion transporters were also detected, these genes may play important roles during potassium deficiency. These results provide valuable information about banana response to low potassium conditions.

Project description:Nitrogen (N) is an abundant and essential macronutrient for plants growth and development processes, especially for the huge banana trees with high biomass. In this paper, we studied the response of banana resists to low N stress ueing Illumina RNA-Seq technology, and analyzed the DEGs associated with the absorption, transport, and ulitilize of nitrogen.

Project description:The present work describes the effects on iron homeostasis when copper transport was deregulated in Arabidopsis thaliana by overexpressing copper transporters (COPTOE). A genome-wide analysis conducted on COPT1OE plants, highlighted that iron homeostasis gene expression was affected, both under copper deficiency and excess. Among the inhibited genes were those encoding the iron uptake machinery and their transcriptional regulators. Subsequently, COPTOE seedlings contained less iron and were more sensitive than controls to iron deficiency. These results emphasized the importance of appropriate spatiotemporal copper uptake for iron homeostasis under copper deficiency. The deregulation of copper-I uptake difficulted the transcriptional activation of the subgroup Ib of basic helix-loop-helix (bHLH-Ib) factors. Oppositely, copper excess inhibited the expression of the master regulator FIT but activate bHLH-Ib expression in COPTOE plants, in both cases leading to the lack of an adequate iron uptake response. As copper increased in the media, iron-III was accumulated in roots, accounting for a defective iron mobilization to the aerial parts, and this effect was exacerbated in COPTOE plants. Thus, iron-III overloading in roots inhibited local iron deficiency responses, aimed to metal uptake from soil, leading to a general lower iron content in the COPTOE seedlings. The understanding of the role of copper uptake in iron metabolism could be applied for increasing crops resistance to iron deficiency

Project description:BACKGROUND:Banana is a nutritionally important crop across tropical and sub-tropical countries in sub-Saharan Africa, Central and South America and Asia. Although cultivars have evolved from diploid, triploid and tetraploid wild Asian species of Musa acuminata (A genome) and Musa balbisiana (B genome), many of today's commercial cultivars are sterile triploids or diploids, with fruit developing via parthenocarpy. As a result of restricted genetic variation, improvement has been limited, resulting in a crop frequently lacking resistance to pests and disease. Considering the importance of molecular tools to facilitate development of disease resistant genotypes, the objectives of this study were to develop polymorphic microsatellite markers from BAC clone sequences for M. acuminata subsp. burmannicoides, var. Calcutta 4. This wild diploid species is used as a donor cultivar in breeding programs as a source of resistance to diverse biotic stresses. FINDINGS:Microsatellite sequences were identified from five Calcutta 4 BAC consensi datasets. Specific primers were designed for 41 loci. Isolated di-nucleotide repeat motifs were the most abundant, followed by tri-nucleotides. From 33 tested loci, 20 displayed polymorphism when screened across 21 diploid M. acuminata accessions, contrasting in resistance to Sigatoka diseases. The number of alleles per SSR locus ranged from two to four, with a total of 56. Six repeat classes were identified, with di-nucleotides the most abundant. Expected heterozygosity values for polymorphic markers ranged from 0.31 to 0.75. CONCLUSIONS:This is the first report identifying polymorphic microsatellite markers from M. acuminata subsp. burmannicoides, var. Calcutta 4 across accessions contrasting in resistance to Sigatoka diseases. These BAC-derived polymorphic microsatellite markers are a useful resource for banana, applicable for genetic map development, germplasm characterization, evolutionary studies and marker assisted selection for traits.
