Lentil (Lens culinaris Medik.) is a cool season legume crop that plays vital roles in food and nutritional security, mostly in the least developed countries. Lentil is often cultivated in dry and semi-dry regions, where the primary abiotic factor is drought, which negatively impacts lentil growth and development, resulting in a reduction of yield....

Mango industry played important roles in the economy of tropical and subtropical regions in China. Embryo abortion, flesh rotten, pericarp stain and so on always result in heavy loss. Transgenic breeding is a potential way for solving these problems. However, dependable protocol for mango transgene has not been reported until now. In this research,...

Wheat fields with weeds are known to contribute significantly to nutrient depletion, which lowers grain yield and quality. Given the unpredictable affects of these intricate and dynamic mixes, the use of herbicide combos and successive applications poses challenges to current standards aimed at maintaining ecosystem health. Thus, a two-year field e...

Arabidopsis thaliana is a short life cycle, small genome, and Brassicaceae family winter annual small flowering plants. It is popularly used as a model organism in genetics and plant biology research, and it is essential to understanding the molecular biology of many plant features, including light sensing and flower formation. It also plays a key...

The world is changing at a breakneck pace, and those who have the ability to change must adapt. Bangladesh's economy is one of the world's fastest-growing. People's eating habits are changing as a result of economic progress and urbanization. These changes are not evenly distributed throughout the urban and rural economic groups, as they are in oth...

In Bangladesh, the total production of rice is about 35 million tons from 11.4 million hectares of land area. However, the population of Bangladesh will reach 200 million by 2050. Most of the mega varieties of Bangladesh reached at yield plateau and further yield improvement protracted for a decade. However, to feed the 200 million populations of t...

A human body is the excellent example of symbiosis in nature. About 10^14 bacteria reside in the human physique as commensal. These microbes make a complex community in entrails is called "gut microbiota". It is estimated that the gut flora is composed more than thousand of different species. These species have various functions in human health and...

An attempt was made in the current study to identify the main-effect and co-localized quantitative trait loci (QTLs) for germination and early seedling growth traits under low-temperature stress (LTS) conditions in rice. The plant material used in this study was an early backcross population of 230 introgression lines (ILs) in BCIF7 generation deri...

In recent years suicide among university students is increasing. In this survey, we have got very important data about the level of mental health issues especially the percentage of suicidal ideation among students. A very strong correlation between the gender of the students and the level of mental health issues was found. The age range was narrow...

De-husked rice of four rice varieties viz., Iratom24, BRRI dhan 58, BRRI dhan 62 and Binnatoa was used to observe their regeneration efficacy and produce somaclones. MS supplemented with different combinations of plant growth regulators; MS + 2,4-D + BAP + NAA, MS + BAP + NAA + Kn + IAA and MS + IBA were used for callus induction, shoot regeneratio...

Background: Arsenic (As) is an unwanted toxic mineral that threatens the major rice-growing regions in the world, especially in South Asia. Rice production in Bangladesh and India depends on As-contaminated groundwater sources for irrigating paddy fields, resulting in elevated amounts of As in the topsoil. Arsenic accumulating in rice plants has a...

The development of green super rice varieties with improved nutrient use efficiency (NuUE) is a vital target area to increase yield and make it more stable under rainfed conditions. In the present study, we followed an early backcross (BC) breeding approach by using a high-yielding and widely adapted Xian variety, Weed Tolerant Rice 1 (WTR-1), as a...

The development of rice cultivars with nutrient use efficiency (NuUE) is highly crucial for sustaining global rice production in Asia and Africa. However, this requires a better understanding of the genetics of NuUE-related traits and their relationship to grain yield. In this study, simultaneous efforts were made to develop nutrient use efficient...

To develop green super rice varieties with high and stable yields under the rainfed conditions and improved nutrient use efficiency (NuUE), a modified backcross (BC) breeding approach was adopted using a high yielding and widely adaptable Xian variety, WTR1, as the recipient and a Geng variety, HAN, as the donor. Starting from the BC1F2 generation,...

In the coming decades, rice production needs to be carried out sustainably to keep the balance between profitability margins and essential resource input costs. Many fertilizers, such as N, depend primarily on fossil fuels, whereas P comes from rock phosphates. How long these reserves will last and sustain agriculture remains to be seen. Therefore,...

Rice is a primary source of energy for more than half of the world's population and 90% of it is produced and consumed in Asia. However, one of the most devastating fungal diseases, rice blast (caused by Pyricularia oryzae), causes 60-100% yield loss (Kihoro et al. 2013) in rice. In this study, eleven popular rice (Oryza sativa Indica) accessions f...

Cut corm and plant spacing on vase life quality.

For selection of aromatic rice lines, twenty six (26) rice genotypes were evaluated for agronomic characteristics and aroma detection through sensory test and genotypic analysis using SSR markers. Grain quality and yield attributes were analyzed after harvesting the grain. Aroma was detected by 1.7% KOH as a sensory test. Based on sensory test, six...
