Rice is a vital component in the diets of many people worldwide, supplying necessary calories for subsistence. Nevertheless, the yield of this crucial agricultural crop is consistently hindered by a range of biotic stresses. Out of these, rice blast, claused mainly by the fungus Magnaporthe oryzae, poses a significant menace to worldwide rice cultivation as well as yield in recent years. The consequences are particularly crucial given the current climate change challenges. In recent decades, substantial progress has been achieved in the development of efficient ways to manage rice blast disease. These procedures entail using a variety of rice genetic resources to find, map, clone, and functionally validate individual resistance (R) genes and quantitative trait loci (QTLs) that provide long-lasting resistance to rice blast disease. Moreover, the replication and practical confirmation of homologous avirulence (Avr) genes in various M. oryzae strains have been crucial in comprehending the fundamental molecular mechanisms of host–pathogen interactions. This article offers a thorough examination of the cloning and functional verification of different R genes and QTLs linked to resistance against rice blast disease. The complex interplay between R–Avr pairings, which contributes to the development of resistance against rice blast throughout a wide range, is thoroughly explained. Finally, this study explores the most recent progress in next-generation sequencing (NGS) and genome editing technologies (GETs), examining their potential uses in improving the treatment of rice blast disease.

Mangifera indica L., the 2nd profusely productive fruit in Pakistan. It is facing an emerging threat of necrosis and blackening of floral buds. In a survey of different mango orchards in Multan, various pathogens were isolated as Pseudomonas syringae pv. syringae, Fusarium mangiferae, Colletotrichum gloeosporoides and Alternaria alternata. From infection frequency assessment, Pseudomonas syringae pv. syringae was found to be the most frequent isolated (79.53%) pathogen followed by Colletotrichum gloeosporoides (57.73%), Alternaria alternata (15.93%) and Fusarium mangiferae (13.33%) at the flowering stage. Infection frequency of Pseudomonas syringae pv. syringae was maximum (93.33%) at stage A and minimum (58.67%) at stage J. It was also proven that Pseudomonas syringae pv. syringae infection was favored by high relative humidity i.e., >80% and low temperature (15-20°C) with r value of +0.85 and -0.71 respectively. Amongst six chemicals evaluated in-vitro by poisoned food technique, copper hydroxide was remarked as most effective at 200 qg/ml concentration with colony inhibition of 37.444% followed by streptomycin sulphate 200 qg/ml (29.67%) as compared to control (0.00%).
