Project description:For tree crops, shortening juvenile phase is a vital strategy for early flowering that ensure to bear fruits in advance to enhance breeding efficiency. In walnut (Juglans regia L.), it usually takes 3-5 years for blooming, but the early flowering (EF) walnut can even flower in a year after planted. The juvenile phase of EF walnut is shorter than the late flowering (LF) walnut, which is more propitious to breeding efficiency. In this study, using RNA sequencing (RNA-seq) and microRNA-seq, we profiled transcriptome-wide identification of gene expression and microRNAs between EF and LF walnuts.
Project description:Low molecular weight (LMW) proteins were purified from English walnuts (J. regia cv. Chandler). The LMW proteins were separated by anion exchange chromatography. The anion exchange fractions were analyzed by SDS-PAGE, and protein bands were excised. In gel trypsin digestion was conducted (following reduction with DTT and alkylation with iodoacetamide). Peptides were separated by RP-HPLC and analyzed with an LTQ Orbitrap XL. Peptide and protein identifications were obtained with Mascot.
