Project description:Masson pine (Pinus massoniana) has evolved some adaptations for growth in low P soils. To elucidate these mechanisms, we investigated global gene expression profiles of the masson pine responding to long-term phosphorus starvation and different Pi levels (P1, 0.01 mM P; P2, 0.06 mM P).

Project description:Masson pine (Pinus massoniana) has evolved some adaptations for growth in low P soils. To elucidate these mechanisms, we investigated global gene expression profiles of the masson pine responding to long-term phosphorus starvation and different Pi levels (P1, 0.01 mM P; P2, 0.06 mM P). Analysis used phosphorus-sufficient treatment RNA as control samples for comparison to the experimental samples (P1 and P2) taken at 12, 24, 48 and 60 day. Indirect comparisons were made across multiple arrays with raw data pulled from different channels for data analysis and comparison to the control data.

Project description:Pine wilt disease is a worldwide dangerous pine disease. We used Masson pine (Pinus massoniana) clones, selected through traditional breeding and testing for 20 years, with high resistance to study the molecular mechanism of resistance to pine wood nematode (PWN, Bursaphelenchus xylophilus). A total of 3491 proteins were identified from seedling tissue, among which 2783 proteins contained quantitative information. Total 42 proteins were up-regulated and 96 proteins were down-regulated in resistant lines. Of them, function enrichment analysis found that significant differences in proteins with pectin esterase activity or peroxidase activity. Proteins participating in salicylic acid metabolism, antioxidant stress reaction, polysaccharide degradation, glucose acid ester sheath lipid biosynthesis, sugar glycosaminoglycans degradation pathway also changed significantly. PRM results showed that pectin acetyl esterase, carbonic anhydrase, peroxidase and chitinase were significantly down-regulated, while aspartic protease was significantly up-regulated, which was consistent with proteomic data.These results suggested that Masson pine could degrade nematode-related proteins by increasing protease to inhibit their infestation, and enhance the resistance of Masson pine to PWN by down-regulating the carbon metabolism to limit available carbon to PWN or to be involved in cell wall components or tissue softening. Most downregulated proteins seem to take back seats prior to pathogen attacks. The highly resistant Masson pine, very likely, has evolved multiple pathways, both the passive and active, to defense against PWN infestation.

Project description:Reforestation is effective in restoring ecosystem functions and enhancing ecosystem services of degraded land. The three most commonly employed reforestation methods of natural reforestation, artificial reforestation with native Masson pine (Pinus massoniana Lamb.), and introduced slash pine (Pinus elliottii Engelm.) plantations were equally successful in biomass yield in southern China. However, it is not known if soil ecosystem functions, such as nitrogen (N) cycling, are also successfully restored. Here, we employed a functional microarray to illustrate soil N cycling. The composition and interactions of N-cycling genes in soils varied significantly with reforestation method. Natural reforestation had more superior organization of N-cycling genes, and higher functional potential (abundance of ammonification, denitrification, assimilatory, and dissimilatory nitrate reduction to ammonium genes) in soils, providing molecular insight into the effects of reforestation.
