“…The expression of both low and high levels of MTI-2 was reported by using Agrobacterium transformation technique in tobacco and Arabidopsis plants leading to resistance against Spodoptera littoralis [94]. The wound-inducible expression of a Bacillus thuringiensis endotoxin gene which directed significant insecticidal gene expression to protect transgenic rice from Chilo suppressalis Walker [95]. Transgenic rice plants were developed by particle bombardment or Agrobacterium-mediated transformation of mpi gene leading to resistance against C. suppressalis (Table 2) [96].…”

Various pathogenic microorganisms (such as fungi, bacteria, viruses and nematodes) affect plant viability and productivity. However, plants combat these pathogens by inducing their defense mechanism to sustain their fitness. The aggregation of pathogenesis-related (PR) proteins in response to invading pathogens is a crucial component of a plant’s self-defense mechanism. PR proteins induce innate resistance in plants through fungal cell wall disintegration, membrane permeabilization, transcriptional suppression, and ribosome inactivation. Earlier studies have demonstrated their crucial role in determining resistance against phytopathogens, making them a promising candidate for developing disease-resistant crop varieties. Plant genetic engineering is a potential approach for developing disease-resistant transgenic crops by employing several PR genes (thaumatin, osmotin-like proteins, chitinases, glucanases, defensins, thionins, oxalate oxidase, oxalate oxidases like proteins/germin-like proteins and LTPs). Furthermore, the overexpression of PR proteins enhances the resistance against phytopathogens. As a result, this chapter gives an overview of PR proteins, including their classification, functional characterization, signaling pathways, mode of action and role in defense against various phytopathogens. It also highlights genetic engineering advances in utilizing these genes singly or synergistically against various phytopathogens to impart disease resistance. Various challenges faced with the products of transgenic technology and synergistic expression of different groups of PR proteins were also discussed.

“…In order to be successful with the chemical control, repeated applications of appropriate insecticide are needed. The insecticidal Cry proteins produced by Bacillus thuringiensis have provided a tool for the control of a wide diversity of insect pests, including the rice SSB, and rice varieties protected from SSB damage through the expression of Bt cry-endotoxin genes (Bt rice) have been developed [36]. The public controversy over genetically modified (GM) crops is, however, limiting the cultivation of Bt rice varieties.…”

Crosstalk between Nutrient Signalling Pathways and Immune Responses in Rice

Rice is a staple food for more than half of the global population. Rice production is, however, severely affected by biotic and abiotic stresses. Fertilisers and pesticides are widely used in rice farming to maintain optimal yield and to prevent losses caused by environmental stress. However, the indiscriminate use of agrochemicals has adverse effects on the environment and human health. Stress caused by nutrient excess or deficiency has an impact on plant disease resistance. The interference of plant responses induced by nutrient stress can result in a positive or negative impact on resistance to pathogen infection. In this review, we explore the effects of combined stresses in rice, focusing on nutrient stress, such as nitrogen and phosphorous supply, and infection by fungal pathogen Magnaporthe oryzae, the causal agent of rice blast disease. Crosstalk between nutrient stress-induced and pathogen-induced signalling pathways in rice is discussed, as well, with particular emphasis on regulatory microRNAs. Understanding the interconnected regulations between nutrient stress and disease resistance will lay a foundation for rationally optimising fertiliser and pesticide use in rice production.
