Project description:To identify oilseed rape genes with a potential role in N-remobilization during leaf senescence of developmentally old leaves in the lower canopy and young leaves in the upper canopy, transcriptomes of leaf number 4 and leaf number 8 of B. napus (cultivar Mozart) were analysed at different harvest time points under mild N deficiency and optimal N fertilization.
Project description:This dataset comprises raw LC-MS data generated from a study examining the root and rhizosphere metabolomes of of Lehmann lovegrass (Eragrostis lehmanniana) and Arizona cottontop (Digitaria californica) in both canopy and inter-canopy regions under velvet mesquite trees (Prosopis velutina) at the Santa Rita Experimental Range (SRER) in Arizona. Samples were collected from twelve 1m x 1m plots representing two dominant plant species (Lehmann lovegrass and Arizona cottontop) across two canopy conditions (closed and open), resulting in 36 root and rhizosphere samples.
Project description:To study the transcriptomic profile of wt and brc1 mutant axillary buds during the shade avoidance response, we simulated a canopy shade with a low R/FR light ratio. We treated plants with white light supplemented with far-red light (Red light = 29 μeinstein · m-2 seg-1, Far-Red light= 146 μeinstein · m-2 seg-1) for 8 hours. Control plants were left for 8 hours in white light (Red light = 29 μeinstein · m-2 seg-1, Far-Red light= 2.2 μeinstein · m-2 seg-1) . Six biological replicates of 7-8 plants were collected for each genotype and condition (wt WL, wt FR, brc1 WL, brc1 FR). Samples were compared wt WL vs wt FR and brc1 WL vs brc1 FR.
Project description:Growth in dense stands induces shade avoidance responses. Early responses to neighbors seem to be assoctaed with touch, not light signalling. We studied gene expression in petioles during early canopy development when leaf hyponasty was visible but altered phytochrome signalling was not yet detectable.
