Project description:Inoculation of endophyte-free (E-) Theobroma cacao leaves with Colletotrichum tropicale (E+), the dominant foliar fungal endophyte in healthy T. cacao, induced significant changes in the expression of hundreds of host genes. Further, E+ leaves exhibit enhanced pathogen resistance, increased lignin and cellulose content, reduced maximum rates of photosynthesis (Amax), and enrichment of nitrogen-15 and carbon-13 isotopes that all correspond to the changes in expression of specific functional genes in related pathways. Moreover, a cacao gene highly up-regulated in E+ leaves increases pathogen resistance apart from any direct endophyte effects. Thus, benefits of increased pathogen resistance in E+ plants are partially due to enhanced induction of intrinsic host defense pathways, and potential costs include reduced photosynthetic capacity and endophyte metabolism of host tissues. Similar effects are likely to be properties of most plant-endophyte interactions, suggesting general relevance to the design and interpretation of studies of genetic and phenotypic expression in plants. The objective of this experiment was to identify Theobroma cacao genes that are differentially expressed between leaves inoculated with fungal endophyte Colletotrichum tropicale (E+ leaves) and control un-inoculated leaves (E- leaves) 3 days post endophyte inoculation. The experiment was conducted in a Percival growth chamber (model I35LL, 115 volts, 1/4 Hp, series: 8503122.16, Percival Scientific, Inc., Perry IA) with 12/12 h light/dark photoperiod and temperatures of 30M-BM-:C and 26M-BM-:C respectively. Inoculation was done by aspersion of endophyte spores (2X10^6 spore/ml) to a group of T. cacao seedlings and a second group of seedlings were maintained as control un-inoculated (E- leaves). Then three biological replicates (each one consisting of one leaf from different plants) per treatment E+ and four leaves per treatment E- leaves) were collected and processed for a two color oligo microarray analysis.

Project description:The applications of plant callus regeneration has been widely spreaded in agricultural improvement. By using immature sorghum embryos as explants, progress in successful genetic transformation has been made in sorghum. However, the underlying mechanism of callus differentiation is still largely unknown in sorghum. Here, we described three types of callus with different abilities of redifferentiation (Callus I-III), undergoing distinct induction from immature embryo in the variety of Hiro-1. In comparison to the non-embryonic Callus III who lost the ability of regeneration, the Callus I produced only some characterized adventitious roots and the embryonic Callus II is sufficient to regenerate whole plants. Genome-wide transcriptome profiles were performed to reveal the underlying mechenisms. The numbers of differentially expressed genes for the three types of callus vary from 5906 to 8029. Principal component analysis analysis demonstrated that gene expression patterns of Callus I and II were totally different from that of Callus III and differential leaves from Callus II, indicating that the compassions of Callus I and II provide clues for revealing regulations of regeneration in sorghum callus. Notably, KEGG and GO analysis showed that plant ribosome, lignin metabolic process, and metabolism of starch and sucrose are main processes that are associated with callus differentiation. Taken together, the results contributed the elucidation of molecular regulation in three types of callus with several regeneration abilities in sorghum.
