- Are species’ range limits simply niche limits writ large? A review of transplant experiments beyond the range. Meta-analysis shows dispersal constrains geographic distribution but extends altitudinal. Biotic interactions important at low elevations and latitudes.
- Herbivores and nutrients control grassland plant diversity via light limitation. Nutrients bad, herbivores good for grassland diversity.
- Economic and ecological implications of geographic bias in pollinator ecology in the light of pollinator declines. Half the data come from 5 countries. Nuff said.
- Integrated crop and livestock systems in Western Europe and South America: A review. Market logic has driven crops and livestock apart, but it should drive them back together again.
- ARABIDOPSIS THALIANA HOMEOBOX25 Uncovers a Role for Gibberellins in Seed Longevity. Seed longevity gene found. No word on whether giberellin treatment can prolong seed life in genebanks. Yet.
- Molecular-level and trait-level differentiation between the cultivated apple (Malus×domestica Borkh.) and its main progenitor Malus sieversii. Status of M. sieversii as main progenitor confirmed. Always good to have more data.
- Adaptation of Cultivated Amaranth (Amaranthus spp.) and Their Wild Relatives in Mexico. One of the wild species could be a source of adaptation for the cultivated under climate change.
- Eat your orchid and have it too: a potentially new conservation formula for Chinese epiphytic medicinal orchids. Nature reserves and cultivation on farms not enough. What you need is “restoration-friendly cultivation.”
- A continental-scale study of seed lifespan in experimental storage examining seed, plant, and environmental traits associated with longevity. Australian seeds are somewhat longer-lived than those from other regions. But there’s plenty of variation, some of which can be explained by different features of the seeds, plants and the specific environment where they grow.
- Inclusive fitness in agriculture. Plants and their root symbionts can get along even better together, with a little help from human selection.
- Genetic diversity analysis for quantitative traits in lentil (Lens culinaris medik.) germplasm. NBPGR seem to be on an evaluation blitz. More power to them. Hope to see the data online soon.
Nibbles: Cowpea blogging, Rice vs wheat psychology, IRRI rice breeding, Wheat disease, African ag success, AGRA seed, Seed certification
- Omnibus edition of recent GCP blog posts on cowpea.
- Chinese rice farmers more sharing and caring than wheat farmers.
- Wonder if that will change with all these fancy new rice varieties coming through.
- Wonder if fusarium ear blight of wheat will change that.
- No such problems in Africa, no sirree.
- Not with all these AGRA-supported seed companies taking off.
- But there’s an international component to that which is being neglected.

- Large-scale microsatellite development in grasspea (Lathyrus sativus L.), an orphan legume of the arid areas. Let the Grasspea Revolution begin.
- High resolution map of eggplant (Solanum melongena) reveals extensive chromosome rearrangement in domesticated members of the Solanaceae. Let the Eggplant Revolution begin.
- Genetic variability in snakegourd (Tricosanthes cucurminata). The Hybrid Snakegourd Revolution is one I’d really like to see.
- Differentially Expressed Genes during Flowering and Grain Filling in Common Bean (Phaseolus vulgaris) Grown under Drought Stress Conditions. We know the drought resistance genes.
- Chloroplast DNA-based genetic diversity and phylogeography of Pyrus betulaefolia (Rosaceae) in Northern China. 3 particularly diverse populations, probably refugia, plus 3 others, identified for conservation.
- Genetic Characterization of the Cacao Cultivar CCN 51: Its Impact and Significance on Global Cacao Improvement and Production. It’s high yielding, resistant to lots of stuff, variable, and an important breeding resource. But it tastes like shit.
- Genotyping of Sicilian grapevine germplasm resources (V. vinifera L.) and their relationships with Sangiovese. Wait, Sangiovese was originally from Sicily?
- Allanblackia, butterflies and cardamom: sustaining livelihoods alongside biodiversity conservation on the forest–agroforestry interface in the East Usambara Mountains, Tanzania. My money is on the butterflies.
- Influence of Ethnolinguistic Diversity on the Sorghum Genetic Patterns in Subsistence Farming Systems in Eastern Kenya. Pattern of sorghum diversity correlates with language groups, not morphology. Improved varieties get given local names and slowly merge with landraces.
- Genetic analysis and molecular characterization of Chinese sesame (Sesamum indicum L.) cultivars using Insertion-Deletion (InDel) and Simple Sequence Repeat (SSR) markers. Improved varieties have narrower genetic base than landraces. Move along there, nothing to see here.
- Innovation of the New Superior Quality Foxtail Millet [Setaria italica (L.) P.Beauv] Variety-Jigu32 with Characteristics of Stress Resistance, Stable and High Yield and Its Physiological Mechanism. This looks like a really dodgy journal. Apologies to them if they’re not, but those ads at the bottom are weird. Anyway, this paper seems to describe the canonical genebank success story: assemble a diverse germplasm collection, evaluate the hell out of it, pick the best, fiddle with them, evaluate the hell out of the results, end up with something better than you started with. Maybe those sesame breeders could learn something…
