    Plant biotic stress: tools and techniques for crop protection
    (Springer Nature Publishing AG, 2026) Acharya, Krishna Ramakrishnan; Chilakala, Aswin Reddy; Senthil-Kumar, Muthappa
    As climate change continues to impact crop yields, developing strategies to enhance plant tolerance to biotic stress has become increasingly important. This requires a thorough evaluation of the tools and methodologies used to manipulate and study biotic stress tolerance. It is crucial to comprehensively understand both conventional and modern techniques, as well as their effectiveness in addressing the specific needs of the crop under study. Detecting diseases at the early stages of plant development can prevent significant losses in large-scale cultivations. Two broad approaches commonly used to mitigate biotic stresses are eliminating causative agents such as fungi, bacteria, nematodes, viruses, or pests, and imparting resistance to the plant. Although there are similarities in the tools and techniques used to address different biotic stresses, each scenario requires dedicated case studies. It is also essential to stay up to date with the latest developments in plant biotechnology to incorporate a cross-disciplinary approach in conducting and validating experiments. This chapter provides an overview of methods covered in this book ranging from molecular breeding to nondestructive techniques that help achieve the goal of safeguarding plant health.

    Recent advances in plant gene silencing methods
    (Springer Nature Publishing AG, 2022) Pandey, Prachi; Mysore, Kirankumar S.; Senthil-Kumar, Muthappa
    With the increasing understanding of fundamentals of gene silencing pathways in plants, various tools and techniques for downregulating the expression of a target gene have been developed across multiple plant species. This chapter provides an insight into the molecular mechanisms of gene silencing and highlights the advancements in various gene silencing approaches. The prominent aspects of different gene silencing methods, their advantages and disadvantages have been discussed. A succinct discussion on the newly emerged microRNA-based technologies like microRNA-induced gene silencing (MIGS) and microRNA-mediated virus-induced gene silencing (MIR-VIGS) are also presented. We have also discussed the gene-editing system like CRISPR-Cas. The prominent bottlenecks in gene silencing methods are the off-target effects and lack of universal applicability. However, the tremendous growth in understanding of this field reflects the potentials for improvements in the currently available approaches and the development of new widely applicable methods for easy, fast, and efficient functional characterization of plant genes.
