Type-III (T3) effectors PthXo1 and AvrXa10 of Xanthomonas oryzae pv. oryzae are translocated into rice cells to inducevirulence and avirulence on susceptible- and resistant-rice varieties Nipponbare and IRBB10, respectively. The translocationneeds the bacterial T3 translocator Hpa1 and rice Oryza sativa plasma membrane protein OsPIP1;3. Here, weemployed the b-lactamase (BlaM) reporter system to observe PthXo1 and AvrXa10 translocation. The system wasestablished to monitor effectors of animal-pathogenic bacteria by quantifying the BlaM hydrolysis product [P] and fluorescenceresonance energy transfer (FRET) of the substrate. The feasibility of the BlaM reporter in rice protoplasts wasevaluated by three criteria. The first criterion indicated differences between both [P] and FRET levels among wild types andOsPIP1;3-overexpressing and OsPIP1;3-silenced lines of both Nipponbare and IRBB10. The second criterion indicateddifferences between [P] and FRET levels in the presence and absence of Hpa1. The last criterion elucidated the coincidenceof PthXo1 translocation with induced expression of the PthXo1 target gene in protoplasts of Nipponbare and the coincidenceof AvrXa10 translocation with induced expression of the AvrXa10 target gene in protoplasts of IRBB10. Theseresults provide an experimental avenue for real-time monitoring of bacterial T3 effector translocation into plant cells with apathological consequence.

To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".
Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.
Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.
Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
