Climate, Plant Organs and species control dissolved nitrogen and phosphorus in fresh litter in a subalpine forest on the eastern Tibetan Plateau
Annals of Forest Science, 2018Co-Authors: Yu Zhang, Jiaping Yang, Wanqin Yang, Bo TanAbstract:Fresh litter contains a higher concentration of dissolved phosphorus (DP) than dissolved nitrogen (DN), which implies a more efficient DN transformation or reabsorption in the subalpine forest on the eastern Tibetan Plateau. Both DN and DP concentrations increased with the increase of mean monthly temperature, although the concentrations were also regulated by Plant Organs and species. The dissolved nitrogen (DN) and dissolved phosphorus (DP) released from fresh litter are important pathways by which total nitrogen and phosphorus are transferred from the vegetation to soil in forest ecosystems. However, few studies have paid attention to the DN and DP in fresh litter, which affects our understanding of the nitrogen and phosphorus cycles. The objectives of this study were to elucidate the dynamic characteristics of the concentrations and storage of DN and DP, and to analyze how DN and DP are affected by different Plant species and Organs, and climate factors. Fresh litter was collected in three plots in a spruce-fir forest and classified by different Plant species and Organs. Concentration and storage of DN and DP in fresh litter were determined and related to the climatic variables that were monthly recorded. The concentration of DP was higher than that of DN in fresh litter, and the concentrations of both elements were determined by Plant Organs and species. Moreover, The DN and DP concentration was positively related to mean monthly temperature, while DN and DP storage was negatively correlated with mean monthly temperature and monthly precipitation. The storage of DN and DP was determined by litter biomass, which the order in litter from different Plant Organs was leaves>twigs>miscellaneous>flowers and fruits. The storage of DN and DP in leaves showed two peaks in April and October, but that in twigs and the miscellaneous showed only one peak in October. Our results indicated that dissolved nitrogen (DN) is transferred and reabsorbed more than dissolved phosphorus (DP) before Plant leaf senescence and other Organs fall. Furthermore, DN and DP were associated with climate, Plant Organs and species in a subalpine forest on the eastern Tibetan Plateau.

Dynamics of endophytic bacteria in Plant in vitro culture: quantification of three bacterial strains in Prunus avium in different Plant Organs and in vitro culture phases
Plant Cell Tissue and Organ Culture (PCTOC), 2016Co-Authors: Mona Quambusch, Jane Brümmer, Kristin Haller, Traud Winkelmann, Melanie BartschAbstract:Endophytic bacteria occurring in Plant in vitro cultures have often been described as contaminants, although these are generally present in all Plant tissues, often with Plant growth promoting effects. The effects of bacterial endophytes in different in vitro culture phases and in different Plant Organs of Prunus avium were studied. In a previous study we investigated the endophytic bacterial community of six registered silvaSELECT® genotypes and found differences in the bacterial community that correlated with propagation success. In this study, quantitative polymerase chain reaction protocols were developed to look at the dynamics of the most abundant endophytes, Mycobacterium spp., Rhodopseudomonas spp., and Microbacterium spp. These endophytes were quantified during propagation and rooting, and the bacterial content in three successive years was evaluated depicting the fluctuation over time. Leaves, stems, and shoots were found to contain bacteria although in different abundance. It was shown that after regeneration via adventitious shoots the bacteria were not eliminated, but showed slightly modified concentrations. The Plant growth promoting traits of the two isolates Rhodopseudomonaspalustris N-I-2 and Microbacterium testaceum D-I-1 were tested in an inoculation experiment, and showed a promotion in rooting of two difficult-to-propagate P. avium genotypes.
