कृषि में कार्बन नैनोट्यूब के साथ इन विट्रो दृष्टिकोण Nanotechnology, like tissue engineering, is built on assembling essential elements to create more complex structures. The process of creating structures and systems with new properties by using materials with at least one physical dimension between 1 and 100 nm is known as nanotechnology. Carbon nanotubes are vital in plant biotechnology because they affect the growth and differentiation of cells, tissues, organs, and entire plants. Carbon nanotubes can also be used to strengthen the structure of scaffolds and give them new properties, such as electrical conductivity, which may help direct cell growth. Carbon nanotubes may be a key biomaterial for making and keeping track of engineered tissue. They have various electronic, thermal, and structural properties that can be described by their diameter, length, chirality, or twist. Carbon nanotubes can be used in four ways that are important for tissue engineering: Tracking and labelling cells. Detecting how cells behave. Changing how cells behave. Improving tissue matrices. Carbon nanotube (CNT) is a versatile allotrope form of carbon with a cylindrical, long, tubular structure of rolled-up graphene sheets. CNTs can have a variety of structures based on their length, thickness, and number of layers. CNTs have become prominent due to their unparalleled mechanical, electrical, thermal, and chemical capabilities. Carbon nanotubes (CNTs) are nanostructured carbon...

अधि‍क फसल वृद्धि के लिए प्लांट ग्रोथ को बढ़ावा देनेे वाले राइज़ोबैक्टेरिया (पीजीपीआर)  का उपयोग  Soil harbors several beneficial microorganisms and some of them colonize in the rhizospheric zone and enhance plant growth. Such bacteria are generally designated as PGPR (Plant Growth-Promoting Rhizobacteria). Plant growth-promoting rhizobacteria (PGPR) was first defined by Kloepper and Schrot  to describe soil bacteria that colonize the roots of plants following inoculation onto seed and that enhance plant growth. Forms of Plant Growth Promoting Rhizobacterial (पौधे का वि‍कास बढाने वाले  राईजोबैट्रीयल के रूप ) Plant growth promoting rhizobacteria can be classified into extracellular plant growth promoting rhizobacteria (ePGPR) and intracellular plant growth promoting rhizobacteria (iPGPR). The ePGPRs may exist in the rhizosphere, on the rhizoplane or in the spaces between the cells of root cortex while iPGPRs locates generally inside the specialized nodular structures of root cells. The bacterial genera such as Agrobacterium, Arthrobacter, Azotobacter, Azospirillum, Bacillus, Burkholderia, Caulobacter, Chromobacterium, Flavobacterium, Micrococcous, Pseudomonas and Serratia belongs to ePGPR. The iPGPR belongs to the family of Rhizobiaceae includes Allorhizobium, Bradyrhizobium, Mesorhizobium and Rhizobium, endophytes and Frankia species both of which can symbiotically fix atmospheric nitrogen with the higher plants. Mechanism Employed by PGPRs in Plant Growth Promotion: (राईजोबैक्‍ट्रीया से पौधे के विकास की क्रि‍यावि‍धि‍) Plant growth promotion by plant growth promoting rhizobacteria is a well-known phenomenon and this growth enhancement is due...
