Cloning and Comparative Analysis of PURPLE ACID PHOSPHATASE 17 Gene Families in Brassica oleracea and Brassica rapa Identification of microRNAs in six solanaceous plants and their potential link with phosphate and mycorrhizal signaling Effects of Phosphate Starvation on Growth State and Phosphorus Uptake of Tomato Seedlings Isolation,function and expression analysis of two wheat phosphate transporter genes Expressions of Three Wheat S-like RNase Genes Were Differentially Regulated by Phosphate Starvation Signaling Components Involved in Plant Responses to Phosphate Starvation Roles of Ubiquitination in the Control of Phosphate Starvation Responses in Plants Comparative genetic analysis of Arabidopsis purple acid phosphatases AtPAP10, AtPAP12, and AtPAP26 provides new insights into their roles in plant adaptation to phosphate deprivation
