The application of pesticides is an integral part of pest and disease management in agriculture since the times unworn. The use of pesticides helps in protecting the crops from the attack of insect pests and disease infestation, improves the crop yield, quality, and storage life of crops. But nowadays farmers usually rely on chemical pesticides to...
Maize is one of the most important crops in the world, and ensuring its successful growth and productivity is crucial for global food security. One way to enhance maize growth and productivity is by improving the colonization of its roots by beneficial microorganisms. In this regard, Serendipita indica, a plant growth–promoting fungus, has gained a...
Flax (Linum usitatissimum L.) or linseed is one of the important industrial crops grown all over the world for seed oil and fiber. Besides oil and fiber, flax offers a wide range of nutritional and therapeutic applications as a feed and food source owing to high amount of α-linolenic acid (omega-3 fatty acid), lignans, protein, minerals, and vitami...
Sulfur is one of the essential nutrients that is required for the adequate growth and development of plants. Sulfur is a structural component of protein disulfide bonds, amino acids, vitamins, and cofactors. Most of the sulfur in soil is present in organic matter and hence not accessible to the plants. Anionic form of sulfur (SO4²⁻) is the primary...
Silicon in the earth’s crust is ubiquitous. It has a wide range of applications in plants, animals, humans, and the overall ecosystem. Though required in trace quantities, the appraisal of silicon in the plant communities against abiotic stress is worth mentioning. But, the in-depth research to understand the mechanism of its uptake in the silicon...
Collagen is the most abundant structural protein in humans, with dozens of sequence variants accounting for over 30% of the protein in an animal body. The fibrillar and hierarchical arrangements of collagen are critical in providing mechanical properties with high strength and toughness. Due to this ubiquitous role in human tissues, collagen-based...
Under constant climatic change and the existing environment, plants are exposed to several adverse factors such as extreme temperatures, high salt, heavy metals (HMs), drought, and pathogens. Prolonged exposure to such adverse conditions results in phytotoxicity and overall retardation of growth and development. Excess of HMs is one of the signific...
Hydrogen sulfide (H2S) has emerged as a potential gasotransmitter in plants with beneficial role in stress amelioration. Despite the various known functions of H2S in plants, not much information is available to explain the associative role of molybdenum (Mo) and hydrogen sulfide (H2S) signaling in plants under arsenic toxicity. In view to address...
Iron (Fe) is a micronutrient required for plant growth and development; however, most Fe forms in soil are not readily available to plants, resulting in low Fe contents in plants and, thereby, causing Fe deficiency in humans. Biofortification through plant‐fungal co‐cultivation might be a sustainable approach to increase crop Fe contents. Therefore...
Molecular basis of light-responsive dynamically tunable biomaterials in biomedical engineering
Biomaterials are a naturally occurring class of fascinating polymers.
Environmental sustainability, biodegradability, wide availability, and
biocompatibility are just some of the unique properties of biomaterials.
Biomaterials are structured of differ...
In the original publication, third author name was incorrectly published.
Heavy metal toxicity is one of the major concerns for agriculture and health. Accumulation of toxic heavy metals at high concentrations in edible parts of crop plants is the primary cause of disease in humans and cattle. A dramatic increase in industrialization, urbanization, and other high anthropogenic activities has led to the accumulation of he...
Plants encounter various abiotic stresses under field conditions. Among them, drought stress adversely affects crop productivity and threatens global food security. Drought stress triggers downstream pathways such as phytohormone homeostasis and their signaling pathways. Consequently, this initiates the biosynthesis of different types of protective...
Main conclusion
Nutrient transporter genes could be a potential candidate for improving crop plants, with enhanced nutrient uptake leading to increased crop yield by providing tolerance against different biotic and abiotic stresses.
Abstract
The world’s food supply is nearing a crisis in meeting the demands of an ever-growing global population, an...
A deficiency of the essential macronutrient sulfur leads to stunted plant growth and yield loss; however, an association with a symbiotic fungus can greatly improve nutrient uptake by the host plant. Here, we identified and functionally characterized a high-affinity sulfate transporter from the endophytic fungus Serendipita indica. SiSulT fulfills...
Drought stress negatively affects crop performance and weakens global food security. It triggers the activation of downstream pathways, mainly through phytohormones homeostasis and their signaling networks, which further initiate the biosynthesis of secondary metabolites (SMs). Roots sense drought stress, the signal travels to the above‐ground tiss...
Phase separation is a concept well described in physics where a system spontaneously exhibits two or more distinct yet coexisting phases at equilibrium. This review describes several popular physical models that serve as a theoretical framework to understand protein phase separation in biological systems, a burgeoning area of research with many cha...
Plants face a continuous threat of abiotic stresses under the changing environment. Because of climate change, water scarcity a significant environmental constraint to plant productivity. Drought has been identified to affect plant growth and development, lead to alteration in quality and quantity of crop production, and result in global food insec...
Sulfur is an important macronutrient required for the growth, development of plants and is a key component of many metabolic pathways. We have functionally characterized a high-affinity sulphate transporter ( PiSulT ) from an endophytic fungus Serendipita indica . The PiSulT belongs to the major facilitator superfamily (MFS) of membrane transporter...
We propose a de novo framework to generate new, structurally stable collagen sequences by incorporating artificial intelligence and a self-evolutionary algorithm. Collagen is the most important and abundant structural protein in the human body. Many interesting properties of collagen require chemical and structural stability. Collagen unfolds from...
Magnesium (Mg) is a crucial macronutrient required for the regular growth of plants. Here we report the identification, isolation and functional characterization of Mg-transporter PiMgT1 in root endophytic fungus Piriformospora indica. We also report the role of P. indica in the improvement of the Mg nutrition of the plant particularly under Mg def...

Piriformospora indica, a root endophytic fungus, promotes growth of the economically important chickpea plant (Cicer arietinum Linn.) and protects it against the pathogenic fungus Botrytis cinerea. Biomass and root development were found to be significantly improved in chickpea plants colonized with P. indica as compared to the plants grown without...
Toxin-antitoxin (TA) systems are highly conserved in members of the Mycobacterium tuberculosis (Mtb) complex and have been proposed to play an important role in physiology and virulence. Nine of these TA systems belong to the mazEF family, encoding the intracellular MazF toxin and its antitoxin, MazE. By overexpressing each of the nine putative Maz...

1. What is the correct pentapeptide sequence of ELPs: GVGVP or VPGVG?
2. Does the sequence "GVGVP" also encode the ELP protein?
3. What differences can be seen if we change the ELP pentapeptide sequences from
VPGVG to GVGVP?

Hi,
I am using EtO technique to sterilize the lyophilized protein. However, EtO adducts in proteins sample is always an issue for further cell related experiments. How can we determine a residual amount of EtO in sample after sterilization. Kindly suggest any advance acceptable methods/techniques.
Thank you so much.

I am working on an extracellular matrix secretory putative protein(Eukaryotic). Through Phosphoproteomics studies, I got to know that phosphorylation sites are available in this protein. The kinase involve in the phosphorylation and location (extracellular or intracellular) of phosphorylation process remain unknown. How can I characterize/identify this?
