5/6) Then, we tested mlo4 responsiveness to exogenous treatments with Lj RALF peptides. We found that mutants are less sensitive to LjRALF34 than WT in terms of root growth inhibition and Ca2+ signalling, supporting recent evidence of MLO as signal amplifiers of the RALF/CrRLK1L signalling

3/6) Surprisingly, no major AM-related phenotypes were visible in mlo4 mutants, but we uncovered clear root developmental phenotypes irrespective of root colonization by AM fungi. mlo4 mutants have shorter and fewer lateral roots, and this is dependent on exogenous Ca2+ levels.

2/6) We found that the promoter of LjMLO4 has a dual expression pattern in roots: strongly activated in arbusculated cells and a basal expression at lateral root primordia and root tips

Strike Day in Italy against government policies that threaten the future of Universities and Research.

The incoming law will result in:
-drastic reduction in government research fundings
-further fragmentation and instability in the post-doc path to faculty positions.
