Reduction of photosynthetic sensitivity in response to abiotic stress in tomato is mediated by a new generation plant activator
No full textBackground: Yield losses as a result of abiotic stress factors present a significant challenge for the future of global food production. While breeding technologies provide potential to combat negative stress-mediated outcomes over time, interventions which act to prime plant tolerance to stress, via the use of phytohormone-based elicitors for example, could act as a valuable tool for crop protection. However, the translation of fundamental biology into functioning solution is often constrained by knowledge-gaps. Results: Photosynthetic and transcriptomic responses were characterised in young tomato (Solanum lycopersicum L.) seedlings in response to pre-treatment with a new plant health activator technology, 'Alethea', followed by a subsequent 100 mM salinity stress. Alethea is a novel proprietary technology composed of three key constituent compounds; the hitherto unexplored compound potassium dihydrojasmonate, an analogue of jasmonic acid; sodium benzoate, a carboxylic acid precursor to salicylic acid, and the alpha-amino acid L-arginine. Salinity treatment led to a maximal 47% reduction in net photosynthetic rate 8 d following NaCl treatment, yet in Alethea pre-treated seedlings, sensitivity to salinity stress was markedly reduced during the experimental period. Microarray analysis of leaf transcriptional responses showed that while salinity stress and Alethea individually impacted on largely non-overlapping, distinct groups of genes, Alethea pre-treatment substantially modified the response to salinity. Alethea affected the expression of genes related to biotic stress, ethylene signalling, cell wall synthesis, redox signalling and photosynthetic processes. Since Alethea had clear effects on photosynthesis/chloroplastic function at the physiological and molecular levels, we also investigated the ability of Alethea to protect various crop species against methyl viologen, a potent generator of oxidative stress in chloroplasts. Alethea pre-treatment produced dramatic reductions in visible foliar necrosis caused by methyl viologen compared with non-primed controls. Conclusions: 'Alethea' technology mediates positive recovery of abiotic stress-induced photosynthetic and foliar loss of performance, which is accompanied by altered transcriptional responses to stress
Coauthor prediction for junior researchers
No full textResearch collaboration can bring in different perspectives and generate more productive results. However, finding an appropriate collaborator can be difficult due to the lacking of sufficient information. Link prediction is a related technique for collaborator discovery; but its focus has been mostly on the core authors who have relatively more publications. We argue that junior researchers actually need more help in finding collaborators. Thus, in this paper, we focus on coauthor prediction for junior researchers. Most of the previous works on coauthor prediction considered global network feature and local network feature separately, or tried to combine local network feature and content feature. But we found a significant improvement by simply combing local network feature and global network feature. We further developed a regularization based approach to incorporate multiple features simultaneously. Experimental results demonstrated that this approach outperformed the simple linear combination of multiple features. We further showed that content features, which were proved to be useful in link prediction, can be easily integrated into our regularization approach. © 2013 Springer-Verlag

Types of Scientific Collaborators: A Perspective of Author Contribution Network
No full textThe purpose of this study is to investigate interaction between collaborators within individual studies by measuring how they made contributions to their studies. Author contribution network is constructed based on the author contribution statements of 140,000 full-text articles in PloS by viewing every collaborator as a node and a shared contribution as an edge. Three types of contributors are identified: general team-players, factotums, and mavericks. The preliminary result suggests that division of labor widely exists in scientific re-search and the latter two types of collaborators are common in small teams.Made available in DSpace on 2018-07-12T15:28:19Z (GMT).

Archaeobotanical evidence of fig (Ficus carica L.) in Europe on the axis of South-North gradient. Preliminary information about Papaver Centre research project
No full textFicus carica L. is one of the oldest domesticated fruit trees in the world. The sweet fruits were widespread across Europe and seeds frequently recorded in many archaeobotanical datasets. The use of figs in diet varied substantially along the geographical South-North European axis. The question is, if this is determined by its local availability or by cultural factors. The aim of the research project in framework of the Papaver Centre is to collect every proper information about chronology and chorology of fig finds in archaeological contexts using archaeobotanical databases in Italy (BRAIN research group), in the Southern part of Germany (ARBODAT Ba-Wü), in Czech archaeobotanical database (CZAD) and in the archaeobotanical databases of Scandinavia (HANSA network project). The main effort of the study is an attempt to explain patterns of fig occurrence in time and trace its diffusion from the Mediterranean to Central and Northern Europe. An additional goal is to explain fig finds in archaeological context by correlating the finds with specific human behaviour.
