Transcriptome-wide analysis of xylogenesis during growing season in Pinus canariensis

Project description:Wood in conifers is mainly composed of tracheids. Some taxa, such as Pinus, present tracheids also in the rays, but are axial tracheids which constitute the vast majority of secondary xylem. Nevertheless, radial and axial parenchyma surrounding constitutive and traumatic resin ducts is known to serve as crucial reserve storage. These reserves are mobilized in response to traumatism, insect and pathogen attacks and defoliation, allowing the synthesis of resin, healing and, in few taxa, even resprouting. However, due to the low proportion of parenchymatic cells in secondary xylem relevant genes involved in their differentiation may have been missed in studies of transcriptomics of conifer wood formation. In this study we have used Pinus canariensis as a model species, given its comparatively high proportion of axial parenchyma. We have prepared two normalized libraries from its cambial zone, covering early- and late-wood differentiation. We have de novo assembled a transcriptome, and have analyzed the transcriptional profiles during the growing season, getting a more complete picture of wood formation in conifers.

Transcriptome-wide analysis of apical shoot development during growing season in Pinus canariensis

Project description:The shoot apical meristem is responsible of seasonal length increase in plants. In woody plants transition from primary to secondary growth is also produced during seasonal apical growth. These processes are controlled by different families of transcription factors. Using a previously constructed Pinus canariensis transcriptome, we designed a genomic microarray to measure the levels of transcription during apical growth. The identification of differentially expressed genes was performed by mean of a time-course analysis.

P. canariensis Resprouting

Project description:Expression profiling by microarray hybridization Newly formed resprouts from Pinus canariensis at three different stages (R0, R1 and R2), and associated phloematic and meristematic tissue, was used for gene expression analysis against control tissues, sampled at the same dates from remote parts of the plant, in order to check transcriptomical variations of an unusual trait in conifers.

Transcriptomic analysis of wound xylem formation in Pinus canariensis.

Project description:Woody plants, especially trees, usually must face several injuries caused by different agents during their lives. Healing of injuries in stem and branches, affecting the vascular cambium and xylem can take several years. In conifers, healing takes place mainly from the remaining vascular cambium in the margin of the wound. The woundwood formed in conifers during healing usually presents malformed and disordered tracheids as well as abundant traumatic resin ducts. These characteristics affect its functionality as water conductor and its technological properties.In this work we analyze for the first time the transcriptomic basis of the formation of traumatic wood in conifers, and reveal some differences with normal early- and late-wood. Microarray analysis of the differentiating traumatic wood, confirmed by quantitative RT-PCR, has revealed alterations in the transcription profile of up to 1408 genes during the first period of healing. We have grouped these genes in twelve clusters, according to their transcription profiles, and have distinguished accordingly two main phases during this first healing.Wounding induces a complete rearrangement of the transcriptional program in the cambial zone close to the injuries. At the first instance, radial growth is stopped, and a complete set of defensive genes, mostly related to biotic stress, are induced. Later on, cambial activity is restored in the lateral borders of the wound, even at a high rate. During this second stage certain genes related to early-wood formation, including genes involved in cell wall formation and transcription factors, are significantly overexpressed, while certain late-wood related genes are repressed. Additionally, significant alterations in the transcription profile of abundant non annotated genes are reported.
