Imaging the 4D choreography of subcellular events in living multicellular organisms at high spatiotemporal resolution could reveal life’s fundamental principles. Yet extracting these principles from petabyte-scale image data requires fusing advanced light microscopy and cutting-edge machine learning models wi...

The effects of different seedli ng-nursing methods,propagation methods and clones were studied by orthogonal test.It was investigated when the trees were 10-month,23-month and 25-month old.The analysis of tree growth,analytical wood and wind damage showed that:(1) Different seedling-nursing meth...
Briefly, the CDB delivery system consists of cutting the junction of plant roots under nonsterile conditions, infecting the upper end with Agrobacterium, taking positive new roots after culture, cutting them into segments and culturing them again to obtain regenerated and transformed plants. Researchers...
Christmas treesEastern white pine (Pinus strobus L.) stem cuttings treated with toothpicks soaked in a 4,500 or 8,000 ppm indolebutyric acid (IBA) solution, dried and inserted into the basal end of the cuttings initiated more roots per cutting than cuttings treated with an 8,000 ppm IBA ...
The injection method requires direct injection of the bacterial suspension into the plant tissue using a sterile syringe. After a variable incubation period, depending on the plant species being studied, hairy roots emerge at wounding sites: the cutting site of explants (in the case of immersion-...
