In dark growth conditions, seedlings develop specific features such as an elongated hypocotyl, a tightly folded apical hook, and non-green cotyledons. This dark-specific process, known as skotomorphogenesis, relies primarily on mitochondria and eventually etioplasts for energy. Our previous research shows that skotomorphogenesis is reprogrammed in...

Establishment of the seedlings is a crucial stage of the plant life cycle. The success of this process is essential for the growth of the mature plant. In Nature, when seeds germinate under the soil, seedlings follow a dark-specific program called skotomorphogenesis, which is characterized by small, non-green cotyledons, long hypocotyl, and an apic...

When covered by a layer of soil, seedling development follows a dark-specific program (skoto-morphogenesis) consisting of small, non-green cotyledons, a long hypocotyl and an apical hook to protect meristematic cells. We recently highlighted the role played by mitochondria in the high energy-consuming reprogramming of Arabidopsis skoto-morphogenesi...

Several factors affect germination and seedling growth for the successful establishment of crops. This study investigates the effect of medium pressure ( ∼ 10 torr) low-frequency glow discharge (LFGD) (Ar + Air) plasma-treated seeds for different periods (1, 3, 6, 8, and 10 min) of wheat. The scanning electron microscopy (SEM) image of the seed sur...

Background Plasma technology is an emerging sector in agriculture. The effect of low-frequency glow discharge (LFGD) plasma at medium pressure (10 torr) on maize morpho-physiological and agronomical behavior was investigated in the current studies. The LFGD plasma act as a secondary messenger to improve maize production. This cutting-edge plasma te...

Plasma technology is an emerging science in the field of agriculture. The goal of this study is to see how low-pressure dielectric barrier discharge (LPDBD) plasma generated from argon/air (Ar/air) mixture affects germination, growth, and yield of maize. LPDBD Ar/air plasma was applied to maize seeds via a bioreactor. Seeds were then planted in the...

We report the draft genome sequence of Klebsiella pneumoniae strain BASUSDALSc45PDB48, isolated from pesticide-contaminated soil; this strain showed the ability to grow in a medium with cypermethrin as the only carbon source. The genome assembly comprised 5,249,704 bp, with 128.17 Ns per 100 kbp, an N50 value of 5,035,968 bp, a GC content of 57.57%...

Plasma agriculture is an emerging technology, although the application of non-thermal plasma in wheat productivity is still in its early stage. This study deciphers the effect and mechanistic basis of non-thermal air-generated LPDBD (low-pressure dielectric barrier discharge) plasma in boosting germination, growth and nutritional properties in whea...

Bioremediation through biodegradation is applied for cleaning up several environmental pollutions including petroleum oil spill containing petrol, diesel, mobil, kerosene, lubricating, etc. which have devastated several endangered terrestrial and aquatic ecosystems. Therefore, the current research was aimed to isolate and identify diesel degrading...

Plasma agriculture is an emerging field. In this report, we studied the effect of medium pressure (~ 10 torr) low-frequency (3–5 kHz) glow discharge (LFGD) plasma on various agronomical and physiological attributes in wheat. Wheat seeds treated by LFGD plasma generated from Argon–Oxygen (Ar + O2) gas mixture and air showed a remarkable enhancement...

COVID-19 Genome sequence at August 2020

We report the sequencing of three severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genomes from Bangladesh. We have identified a unique mutation (NSP2_V480I) in one of the sequenced genomes (isolate hCoV-19/Bangladesh/BCSIR-NILMRC-006/2020) compared to the sequences available in the Global Initiative on Sharing All Influenza Data (GISAI...

Sustainable management of iron (Fe) deficiency through the microbial association is highly desirable to ensure crop yield. This study elucidates whether and how arbuscular mycorrhizal fungi (AMF) ameliorate Fe deficiency symptoms in sorghum. AMF inoculation showed a significant improvement in plant biomass, chlorophyll score, Fv/Fm (quantum efficie...

Applications of nonthermal plasmas in agriculture are drawing much interest to the researchers because of its significant effects on seed germination, plant growth and development. This study investigates the effects of plasma activated water (PAW) on seed germination, seedling growth and antioxidant enzymes of black gram (Vigna mungo L.) (Local na...

Cadmium (Cd) is detrimental to crops and the environment. This work examines the natural mechanisms underlying silicon‐ (Si‐)directed Cd detoxification in rice plants. The addition of Si to plants under Cd stress caused significant improvements in morphological parameters, chlorophyll score, F v /F m and total soluble protein concentration compared...

Effects of black gram (vigna mungo L.cv. Barimash 3) seed treatments with 400 torr dielectric barrier discharge (DBD) air plasma on seed surface morphology, seed germination, seedling growth and antioxidant enzyme activities in the roots, shoots and leaves were investigated. The plasma discharge voltage, frequency, electrode spacing, gas temperatur...

Chemical fertilization in agriculture is threatening to the ecosystem. Therefore, the use of eco-friendly stimulant for crop revolution is highly desirable.
