  • Intraspecific variation in heritable secondary metabolites and defensive strategies in a relict tree

    Abstract Aims Key herbivory interaction traits such as plant defensive compounds may differ among populations of a single species due to the spatial variation in herbivore feeding guilds and the strength of the interaction. Moreover, the genealogy of population lineages could represent an additional source of variation interacting with the predominant eco-clinal trends. We ...

  • Defense characteristics of seral deciduous broad-leaved tree seedlings grown under differing levels of CO2 and nitrogen

    Mixed broad-leaved forests are abundantly populated by several kinds of herbivore species in northern Japan. The life of herbivores depends strongly on the quality of food leaves. Leaf quality is changing with increasing atmospheric CO2 and nitrogen deposition. Four seral species of deciduous broad-leaved tree seedlings (alder, birch, oak and maple) were raised in all four combinations of two ...

  • What is it about this soil that protects plants from devastating disease?

    Figuring out why certain soils keep plant parasites at bay could be a boon for agriculture around the globe Plants around the world are constantly under attack — often with big implications for humans. In the 1960s, millions of elm trees in Britain, France and the U.S. fell victim to Dutch elm disease, which clogs the vessels that carry life-giving water to the trees’ leaves. ...

  • Induced Genome-wide binding of three Arabidopsis WRKY transcription factors during early MAMP-Triggered Immunity

    Abstract During microbial-associated molecular pattern (MAMP)-triggered immunity (MTI) molecules derived from microbes are perceived by cell surface receptors and upon signaling to the nucleus initiate a massive transcriptional reprogramming critical to mount an appropriate host defense response. WRKY transcription factors play an important role in regulating these transcriptional processes. ...

  • Nano silicon dioxide mitigates the adverse effects of salt stress on Cucurbita pepo L

    Nanotechnology, an emerging science, has advanced research in almost all fields of technology. The aim of the present study was to evaluate the role of nano silicon dioxide (nSiO) in plant resistance to salt stress through improving the antioxidant system of squash (Cucurbita pepo L. cv. White Bush Marrow). We found that seeds treated with NaCl showed reduced germination percentage, vigor ...

  • Biopesticides Examined for Role in Field Production

    Biopesticides deserve respect. Once derided as snake oil, today’s products have proven benefits in suppressing pest organisms. Whether they activate plant defenses, parasitize or inhibit pathogen growth or make the environment less favourable to disease, they can play an integral role in crop protection. While the greenhouse sector first excelled at incorporating biopesticides in controlled ...

  • Characterization of biosynthetic pathways for the production of the volatile homoterpenes DMNT and TMTT in Zea mays

    Plant volatiles not only have multiple defense functions against herbivores, fungi, and bacteria, but also have been implicated in signaling within the plant and towards other organisms. Elucidating the function of individual plant volatiles will require more knowledge of their biosynthesis and regulation in response to external stimuli. By exploiting the variation of herbivore-induced volatiles ...

  • Effect of ethylene on fruits and vegetables rotting

    In the latest edition of Bioconservacion's Partner Meeting with all its partners from the post-harvest sector, we had the good fortune to have Professor Emeritus Ron Wills from the University of Newcastle in Australia. Dr Wills, with over 50 years experience researching agronomy, agriculture and post-harvest techniques is undoubtedly a leader in the sector and one of the great experts on ethylene ...

  • Bottom up in Indonesia!

    Last week, I visited Indonesia together with Femke Tonneijck from Wetlands International to meet our partners that are involved in the development of a Building with Nature approach to solve the severe erosion along the muddy Northern coast of Central Java (Demak district). Deltares and Wetlands International have ...

  • Implementing Research : Georgia Takes Many Routes to Recycle Food Residuals

     PETROLEUM HYDROCARBON LEVELS “One unique local characteristic (and treatment difficulty) we encountered in our composting program,” says Stan Konno, PWC environmental department director head, “is the high level of diesel range total petroleum hydrocarbon (TPH) content in the sludge from the WWTF at Fort Kamehameha.” Oil from past leaks in pipelines and tanks — which go back to 1941 — ...

  • Compost science journal of advocacy and foresight

    SEVERAL months ago, I started on a journey through the pages of Compost Science, beginning with the Spring, 1960 inaugural issue. I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...

  • Saddle up, soybean seed pigments: argonaute5 in spatially regulated silencing of Chalcone Synthase genes

    Most soybean seeds you see, whether in bins at the store, or in train cars as a commodity crop, have a yellow seed coat that may have only a tiny fleck of dark pigment at the hilum, where the seed attaches to the pod. The predominant yellow color results from silencing of chalcone synthase (CHS) genes by RNA interference (RNAi) due to the presence of I or ii alleles. The ii allele has an inverted ...

  • How a new way of thinking about soil sparked a national movement in agriculture

    For three weeks every month, Ray Archuleta captivates audiences with a few handfuls of soil. He begins with two clumps, dropping them into water. The soil from a farm where the soil isn’t tilled holds together, while the tilled soil immediately disperses, indicating poor soil structure. Next, volunteers from the audience — mostly farmers and ranchers — pour water over a soil ...
