A DNA diagnostic system has been developed by using a bacterial reporter probe. DNA hybridization-driven magnetic isolation of E. coli, followed by exponential bacterial growth and fluorescent protein expression, allows the translation of a target binding event into a vastly amplified signal and a highly sensitive/selective detection platform.

This study aimed to develop a reliable and efficient genetic transformation method for the ornamental Indian Lotus (Nelumbo nucifera Gaertn.) using the sonication-assisted Rhizobium radiobacter-mediated transformation technique. To conduct the transformation, shoot apical meristem explants were infected with Rhizobium radiobacter (synonym Agrobacterium tumefaciens) strain LBA 4404 containing a binary vector pBI121 that harbours the GUS reporter gene (uidA) and kanamycin resistance gene nptII for plant selection.

Small regulatory RNAs (sRNA) have been shown to play a large role in the management of stress responses in and other bacteria. Upon fluctuations in nutrient availability and exposure to antimicrobials and superoxide-generating agents, the MicF sRNA in has been shown to regulate a small set of genes involved in the management of membrane permeability. Currently, it is unknown whether MicF acts on other processes to mediate the response to these agents.

The ESX-1 secretion system is critical for the virulence of as well as for conjugation in the saprophytic model . EsxB (CFP-10) and EsxA (ESAT-6) are secreted effectors required for the function of ESX-1 systems. While some transcription factors regulating the expression of and have been identified, little work has addressed their promoter structures or other determinants of their expression.

Viruses, known for causing widespread biological harm and even extinction, pose significant challenges to public health. Virus detection is crucial for accurate disease diagnosis and preventing the spread of infections. Recently, the outstanding analytical performance of CRISPR/Cas biosensors has shown great potential and they have been considered as augmenting methods for reverse-transcription polymerase chain reaction (RT-PCR), which was the gold standard for nucleic acid detection.
