Project description:Wood density is a foundamental quality trait for structural timber, bioenergy and pulp industries. We investigated genes differentially transcribed in radiate pine juvneile trees with distinct wood density using cDNA microarrays.
Project description:Bacteria from anaerobic Microcolony-seq condition that were kept at the -80C were regrown in liquid LB at 37C for 5 hours. DNA was extracted from 1 mL of bacteria using the DNeasy Blood & Tissue Kit (Qiagen). Library preparation and sequencing was carried out by the Genomics Applications Laboratory, Core Research Facility, Faculty of Medicine, The Hebrew University of Jerusalem, Jerusalem, Israel. DNA libraries for sequencing were prepared using the kit (ILMN DNA LP (M) Tagmentation (24 Samples, IPB) 20060060) (Illumina, Inc., USA) according to manufacturing instructions. At least 100X sequencing depth for each nucleotide in each sample was targeted. Samples were deep-sequenced with the Nextseq500 machine using the 150-cycle mid output kit (Illumina, Inc., USA) from the forward read direction.
Project description:Wood stiffness is the most important wood quality trait of forest trees for structural timber production. We investigated genes differentially transcribed in radiate pine trees with distinct wood stiffness using bulked segregant analysis (BSA) and cDNA microarrays. Transcript accumulation in earlywood (EW) and latewood (LW) of high (HS) and low stiffness (LS) trees in two progeny trials was compared.

Project description:Knot-free timber production in Cunninghamia lanceolata depends critically on internodal characteristics, yet the mechanisms governing internode elongation remain poorly understood, hindering breeding efforts for longer-internode varieties. In this study, we selected two clones with distinct internodal traits (the C1 clone exhibited a 25.03% longer internodal length than the C11 clone) as materials. Enzyme-linked immunosorbent assay (ELISA) and RNA sequencing were used to investigate dynamics in endogenous hormones and transcriptional regulation in internodal growth. Results showed that the difference in indole-3-acetic acid (IAA) rhythms in apical buds is a key factor of C1?s longer internodal growth; higher levels of IAA and cytokinins in the apical buds of C1 may support sustained internodal growth; upregulated IAA-related genes in upper phloem (PIN1 and SAURs), which are involved in polar transport and signal response, indicates a stronger capacity to establish apical dominance. Hormone transport may be regulated by very long-chain fatty acids (VLCFAs). Consistent with reduced brassinosteroid activity, genes involved in VLCFA biosynthesis and transport were generally lower in C1, implying excessive VLCFA accumulation in C11 may be negative to IAA transporting and internode growth. This study offers a preliminary insight into internodal growth mechanisms influenced by hormone biosynthesis and transport in C. lanceolata., providing a basis for genetic improvement, germplasm selection, and exogenous hormone applications in knot-free timber cultivation.
