In the last 20 years several varieties and breeding lines of tomato have been developed which possess immunity from C. fulvum races 1 to 9. Vagabond, Vinequeen, V548 obtained their L. hirsutum Humb. Bonpl.; V501 var. glabralum Muller; V542, Vantage, Waltham Mold Proof Forcing No. 22, etc. peruvianum (L.) Mill.; V545 pimpinellifolium (Jusl.) Mill. Studies are reported herein on genetic bases resistance in these varieties.Single genes for race 6 were isolated lines. Crosses between indicated...
Seaweed farming has the potential to produce feedstocks for many applications, including food, feeds, fertilizers, biostimulants, and biofuels. Seaweeds have advantages over land-based biomass in that they require no freshwater inputs allocation of arable land. To date, seaweed not been practiced at scales relevant meaningful biofuel production. Here we describe a techno-economic model large-scale farms its application cultivation cool temperate species Saccharina latissima (sugar kelp)...
Warming sea temperatures are threatening global kelp populations, including sugar (Saccharina latissima), one of the most commonly farmed species. For future aquaculture and restoration, we must identify individuals with natural adaptations to cope heat. If heat tolerance adult can be predicted by assessment at early-life gametophyte stage (prior fertilization), then accelerate breeding heat-tolerant strains. We developed a high-throughput method for assessing physiological stress under...
Abstract The US DOE/ARPA‐E MARINER program funded a 4‐year project to determine an optimal way grow kelps in large, nearshore and offshore arrays for the eventual purpose of biofuel production with goal keeping cost below $80 USD per dry metric ton kelp. This specifically looked at how Saccharina latissima can be grown Gulf Alaska reach that goal. There were three major aspects research: (1) optimize nursery seeding lines outplanting; (2) design economical, modular outplanting structure; (3)...
An assessment of genetic diversity marine populations is critical not only for the understanding and preservation natural biodiversity but also its economic potential. As commercial demand rises resources, it to generate baseline information monitoring wild populations. Furthermore, anthropogenic stressors on coastal environment, such as warming sea surface temperatures overharvesting populations, are leading destruction keystone species kelps. In this study, we conducted a fine-scale...
Abstract Dunaliella salina accumulates large amounts of intracellular glycerol in response to the increases salt concentration, thus is a potential source for producing fuel grade as an alternative biodiesel-derived crude glycerol. D. lacks cell wall; therefore mode harvesting cells critical avoid disruption caused by extreme engineering conditions. This study explored and leakage under various centrifugal stresses during harvesting. Results show g-force lower than 5000 g little disruption,...
Saccharina latissima (sugar kelp) is one of the most widely cultivated brown marine macroalgae species in North Atlantic and eastern Pacific Oceans. To meet expanding demands sugar kelp mariculture industry, selecting breeding that best suited to offshore farm environments becoming necessary. end, a multi-year, multi-institutional program was established by U.S. Department Energy's (DOE) Advanced Research Projects Agency-Energy (ARPA-E) Macroalgae Inspiring Novel Energy Resources (MARINER)...
Introduction Sugar kelp ( Saccharina latissima ) has a biphasic life cycle, allowing selection on both thediploid sporophytes (SPs) and haploid gametophytes (GPs). Methods We trained genomic (GS) model from farm-tested SP phenotypic data used mixed-ploidy additive relationship matrix to predict GP breeding values. Topranked GPs were make crosses for further farm evaluation. The included 866 individuals: a) founder SPs sampled the wild; b) progeny founders; c) Farm-tested crossed b); d) SPs....
Abstract Our team has initiated a selective breeding program for regional strains of sugar kelp, Saccharina latissima , to improve the competitiveness kelp farming in United States. Within our program, we also include an endemic putative species, angustissima locally referred as skinny kelp. We crossed uniclonal gametophyte cultures derived from 37 wild‐collected blades representing five and one strain produce 104 unique crosses. Each cross was outplanted on near‐shore research farm located...
Intensive surveys of the physiological races Cladosporium fulvum Cke. have been carried out during past decade in southwestern Ontario, as a result which seven such identified. These are separated by differential reactions following hosts: Lycopersicon esculentum Mill. varieties Potentate, Stirling Castle, Vetomold, V-121, and V-473; L. pimpinellifolium (Jusl.) Mill., Vineland, No. 160 11-22-15 strains; hirsutum Humb. Bonpl. var. glabratum Muller. Evidence is presented that only two these...
The effects of infestation the roots tomato seedlings with naturally occurring rhizoplane fungi on uptake various nutrients has been studied. Fusarium sp. suppressed radioactive phosphate, sulphate, bicarbonate, and glucose by varieties Bonny Best Geneva 11. Trichoderma viride Pers. inorganic ions but increased in Moscow Loran Blood. Marked differences were observed distribution radioactivity among soluble compounds shoots infested noninfested plants after supply C 14 -labelled or...
Abstract Though Saccharina japonica cultivation has been established for many decades in East Asian countries, the domestication process of sugar kelp (Saccharina latissima) Northeast United States is still at its infancy. In this study, by using data from our breeding experience, we will demonstrate how obstacles accelerated genetic gain can be assessed simulation approaches that inform resource allocation decisions. Thus far, have used 140 wild sporophytes were sampled 2018 northern Gulf...
Abstract Interest in farming kelps has grown beyond using kelp for food, feed or biofuels. There is considerable interest generating biomass from seaweed use bioplastics and other products that would substitute petroleum-derived products. For these uses to be viable, large amounts of are needed. Very farms can expensive build maintain, leading the need optimize per unit area. Although close spacing growlines lead poor growth, a viable approach may grow two species together: one hangs down...
A new race of Cladosporium fulvum Cke., the tomato leaf mold pathogen, appeared on lines Purdue 38 and 135 in commercial greenhouses vicinity Cincinnati, Ohio, fall 1962. These incorporate from L. hirsutum gene Cf 4 , which confers immunity to races 1 9. Greenhouse inoculations indicate that 10 is similar pathogenicity against 2 3 . Varieties such as Vetomold, Tucker's Forcing, Manalucie, contain are accordingly immune 10.
The density of fungi in the rhizosphere and nature on rhizoplane five varieties tomato, some susceptible resistant to infection by Verticillium, were determined. numbers higher rhizospheres varieties, Bonny Best John Baer, than ones, Loran Blood Moscow. However, variety Geneva 11, did not differ appreciably from those for varieties. Among isolated rhizoplane, a species Fusarium was dominant Best, 11 Trichoderma viride Pers. In vitro, show antagonism, either against Verticillium or amongst...
