Quantum dots (QDs) are important in the research and industrial fields due to their diverse properties and technological importance. Recently, QDs have been found to be suitable for biological, biomedical, agricultural, and food science applications. Many research articles, review papers, and internet sources have published on the use of QDs to improve plant growth and yield, but a comprehensive overview in book form has not been available to date. This book provides detailed information on synthesis, functionalization, and the use of various types of quantum dots for plant systems. It also addresses the current state of knowledge on sensing mechanisms of QD-based biosensors used for microorganisms, including bacteria, fungi, and plant virus detection. This book also offers in-depth knowledge related to QDs used for plant growth, nutrients, and plant protection from micro-organisms. This volume is beneficial as one comprehensive resource for students, researchers, scientists, technicians, academicians, and industrialists.

In this study the role of epicuticular wax in transmission of CLCuV has been studied. Epicuticular waxes plays very important role in hindering the attachment of insects to the leaves. In this study the wax deficient mutant plants GaWM3 were used as experimental plants while Gossypium arboreum (786) were used as negatively controlled plants as it is reported that whitefly can not transmit virus in it and G. hirsutum (MNH-93) were taken as negative and positive control plants because it has severe viral attack in past. It is important to mention here that GaWM3 were produced in our laboratory at CEMB from Gossypium arboreum (786) with the only difference of having 50% less wax than Gossypium arboreum (786). It was found that the G. hirsutum (MNH-93) was CLCuV positive and G. arboreum (786) was CLCuV negative. But most strikingly the wax deficient GaWM3 mutant plants which contain 50% less than G. arboreum (786) wax were CLCuV positive while the plants from which these mutants were made (G. arboreum,786) were CLCuV negative. If wax act act a barrier than, the damage of CLCuV on cotton can be overcome by by increasing the wax content.

COMBINING ABILITY ANALYSIS, IS BEING WIDELY UTILIZED BY PLANT BREEDERS, FOR BEST COMBINATION ANALYSIS IN DIFFERENT CROPS. TOMATO, AS GROWN IN ALL PARTS OF THE WORLD, NEEDS CONTINUOUS SELECTION FOR VARYING ENVIRONMENTS AND CHANGING CLIMATIC CONDITIONS. ALSO, THE GERM PLASM CONSERVATION IS MAIN OBJECTIVE FOR UTILIZING IN BREEDING PROGRAMS. HERE COMBINING ABILITY OF DIFFERENT PARENTS HAS BEEN EXPLORED FOR YIELD AND ENVIRONMENTAL STABILITY OF HYBRIDS FOR SUSTAINABLE CROP PRODUCTION. DIFFERENT TRAITS, INFLUENCING YIELD AND ENVIRONMENTAL STABILITY HAS BEEN CHECKED USING GCA AND SCA ANALYSIS.
