This method is accessible to any laboratory familiar with basic molecular cloning procedures and the apple leaf-mediated agro-transformation technique. Phosphorus (P) is an essential macronutrient that is often limited in agricultural systems. Determining inorganic phosphate (Pi) contents of plant tissues is crucial for evaluating plant P status. Here, we present a simple, high-throughput colorimetric microplate technique to measure Pi contents in rice ( ) leaf tissues, based on the molybdenum blue reaction. We used a hole puncher to sample small equal areas of leaf tissue for Pi extraction. We removed the leaf grinding and weighing steps, which are time-consuming and normally required to release Pi from the tissues and to measure the biomass for data normalization, respectively. We showed that the punching method yielded comparable results to the conventional grinding method for two rice cultivars grown under various levels of P supply. Compared with existing techniques, this protocol is more suited to an initial screening, enabling one researcher to determine the Pi contents of thousands of rice leaf samples within a few hours.

The family Salicaceae has proved taxonomically challenging, especially in the genus , which is speciose and features frequent hybridization and polyploidy. Past efforts to reconstruct the phylogeny with molecular barcodes have failed to resolve the species relationships of many sections of the genus. We used the wealth of sequence data in the family to design sequence capture probes to target regions of 300-1200 bp of exonic regions of 972 genes. We recovered sequence data for nearly all of
