Abstract Jute ( Corchorus sp.) is one of the most important sources natural fibre, covering ∼80% global bast fibre production 1 . Only olitorius and capsularis are commercially cultivated, though there more than 100 species 2 in Malvaceae family. Here we describe high-quality draft genomes these two their comparisons at functional genomics level to support tailor-designed breeding. The assemblies cover 91.6% 82.2% estimated genome sizes for C. , respectively. In total, 37,031 30,096 genes...
The rice landrace Horkuch, endemic to the southern saline coast of Bangladesh, is known have salt tolerance traits and can therefore contribute a high yielding recipient for breeding purposes. In this study, we reciprocally crossed Horkuch with but sensitive IR29 detect complement genes that were responsible conferring versus sensitivity at seedling developmental stage. We looked tolerant F3 families from individual F2 segregating plants analyzed them differential gene expressions using...
Soil salinity is one of the most challenging problems that restricts normal growth and production rice worldwide. It has therefore become very important to produce more saline tolerant varieties. This study shows constitutive over-expression vacuolar Na+/H+ antiporter gene (OsNHX1) from landrace (Pokkali) attainment enhanced level tolerance in transgenic plants. also inclusion complete un-translated regions alternatively spliced OsNHX1 provides a higher rice. Two separate transformation...
Abstract Global increase in salinity levels has made it imperative to identify novel sources of genetic variation for tolerance traits, especially rice. The rice landrace Horkuch, endemic the saline coastal area Bangladesh, was used this study as source reciprocal crosses with sensitive but high-yielding IR29 variety discovering transcriptional associated salt resulting populations. cytoplasmic effect Horkuch background leaves under stress showed functional enrichment signal transduction,...
Introduction COVID-19 pandemic hit Bangladesh with relatively low intensity, unlike its neighbors India and European countries USA. Methods The present report included data of 8,480 individuals tested for RT-PCR the workers officials from readymade garments (RMG) industry in Chandra area Gazipur. looked into clinic-demographic factors associated susceptibility condition. Result elucidated to SARS-CoV-2 based on age, gender, pre-existing health conditions, presence symptoms. It was observed...
Good donors in breeding for salt tolerance are a prerequisite food security under changing climatic conditions. Horkuch, farmer-popular tolerant rice (Oryza sativa L.) variety from the south-west coast of Bangladesh was characterised up to maturity NaCl stress, together with modern (BRRI dhan41), sensitive control dhan29) and Pokkali, salt-tolerant benchmark rice. Horkuch had low reduction shoot biomass, Na : K ratio flag leaves, percent yield good partitioning older maintained high levels...
Bangladesh is a reservoir of diverse rice germplasm and home to many landraces with unique, important traits. Molecular characterization these value for their identification, preservation, potential use in breeding programs. Thirty-eight from different regions including some high yielding BRRI varieties were analyzed by 34 polymorphic microsatellite markers total 258 reproducible alleles. The analysis could locate unique identifiers 21 genotypes, making the latter potentially amenable...
Salinity has a significant negative impact on production of rice. To cope with the increased soil salinity due to climate change, we need develop salt tolerant rice varieties that can maintain their high yield. Rice landraces indigenous coastal Bangladesh be great resource study genetic basis adaptation. In this study, implemented QTL analysis framework reciprocal mapping population developed from landrace Horkuch and yielding variety IR29. Our aim was detect loci contributes adaptive...
Reverse transcription loop‐mediated isothermal amplification (RT‐LAMP) is a molecular method that can detect SARS‐CoV‐2 in shorter time than the current gold‐standard diagnostic reverse transcription‐polymerase chain reaction (RT‐PCR). However, previously developed RT‐LAMP assays have mostly relied on highly subjective visual colorimetric interpretation. In this study, an assay was with quantitative measurement of pH using novel portable biosensor compared to qualitative interpretation and...
At the cellular level, Salt Overly Sensitive (SOS) signaling pathway comprising SOS3, SOS2, and SOS1 has been proposed to mediate under salt stress maintain ion (Na+) homeostasis. In this regulatory pathway, both OsSOS1 encoding plasma membrane OsNHX1 vacuolar Na+/H+ antiporters are regulated by SOS3?SOS2 protein kinase complex. present study, rice variety BRRI dhan28 - which is popular with farmers high yielding, but sensitive, was transformed gene isolated from tolerant Pokkali driven...
Abstract Pseudomonas aeruginosa uses quorum sensing (QS) to modulate the expression of several virulence factors that enable it establish severe infections. The QS system in P. is complex, intricate and dominated by two main N -acyl-homoserine lactone circuits, LasRI RhlRI. These systems work a hierarchical fashion with at top, directly regulating Together these circuits regulate associated genes, metabolites, enzymes . Paradoxically, LasR mutants are frequently isolated from chronic...
Soil salinity adversely affects plant growth, development and disturbs intracellular ion homeostasis which results in cellular toxicity. The salt overly sensitive 1 (SOS1) gene is a critical component of tolerance many species encodes plasma membrane Na+/H+ antiporter that plays an important role germination growth saline environments. In the current study, coding sequence SOS1 (3447 bp) was amplified from Bangladeshi rice landrace, Pokkali, by applying fusion PCR strategy. amplicons were...
Bangladesh lies within the origin of rice biodiversity and is home to many genotypes with varying amylose content grain size. There however no precise data on their correlation size type. Yet these classifications governs taste, cooking nutritional quality rice, ultimately determining its consumer preference market price. Correlating will be useful information for Diabetics, particularly due unproven assumption that long grains correlate high vice versa. In this study, 131 long, medium short...

To cope with the increased soil salinity due to climate change, we need develop salt tolerant rice varieties that can maintain their high yield. Rice landraces indigenous coastal Bangladesh be great resource study genetic basis adaptation. In this study, implemented QTL analysis framework reciprocal mapping population between landrace Horkuch and yieldingrice variety IR29 . Our aim was detect loci contributes adaptive...
Introduction Salinity is a complex environmental stress that affects the growth and production of rice worldwide. But there are some landraces in coastal regions can survive presence highly saline conditions. An understanding molecular attributes contributing to salinity tolerance these genotypes important for developing salt-tolerant high yielding modern ensure food security. Therefore, we investigated role functional differences two K + salt-responsive transporters. These OsTPKa or...
The coastal area of Bangladesh is affected by soil salinity which threatens rice production. Saline soils are mainly caused excessive Na+ interferes with the uptake essential nutrient K+. Certain K+ transporters may cause leakage ions and OsAKT1 transporter was earlier shown to be downregulated under salt stress in a tolerant landrace called Horkuch. We therefore targeted this gene for Crispr-mediated downregulation Agrobacterium-mediated planta transformation sensitive IR29 rice....
The rice (Oryza sativa L.) landrace Horkuch from Bangladesh maintains efficient photosynthesis and detoxification under salt stress was therefore considered to be a useful donor for tolerance traits. Reciprocally crossed bi-parental mapping populations were generated salt-tolerant high-yielding salt-sensitive variety IR29, in order identify superior lines as donors. present study reports on the phenotypic screening data of ~300 F3 segregating reciprocal cross their parental seedlings subset...
Salinity is one of the most critical environmental problems, which causes plant growth retardation by disturbing intracellular ion homeostasis. The Na+/H+ antiporter plays an important role in resistance to salt stress sequestering Na+ exchange for H+ across vacuolar membranes. In current study, coding regions two Arabidopsis antiporters (AtNHX1 and AtNHX2) rice (OsNHX1) were amplified target specific PCR. PCR amplicons first cloned into pENTR/D-TOPO later recombined with a destination...
