- Isolation and detection of differential genes in hot pepper (Capsicum annuum L.) after space flight using AFLP markers. Space flight resulted in some new traits.
- Addressing chronic malnutrition through multi-sectoral, sustainable approaches: a review of the causes and consequences. Many causes, many consequences, many things that could be done. Too complicated? Here’s a ray of hope for you: “…diet diversity for children older than 6 months, measured as consumption of at least four food groups, has been found to have the strongest impact on the prevention of stunting compared to other IYCF interventions.”
- Antioxidants and sensory properties of the infusions of wild passiflora from Brazilian savannah: potential as functional beverages. Possibly better than green tea, and just as acceptable, except for P. alata, which is inexplicably bitter. Which personally makes me want to try it even more.
- Formative Research on Acceptability of Pearl Millet in Rural Eastern Kenya – A Pilot Study. A lot of families were willing to barter their maize for it.
- Genetic relationships between wild progenitor pear (Pyrus L.) species and local cultivars native to Georgia, South Caucasus. Local Georgian cultivars are close to the local wild species, which is genetically distinct in that country compared to others represented in the USDA collection.
- Traceability of 9 Portuguese cattle breeds with PDO products in the market using microsatellites. You can do it, but will there really be viable Protected Denomination of Origin products based on different Portuguese cattle breeds?
- Divergent adaptation to climate variability: A case study of pastoral and agricultural societies in Niger. What’s good for the farmer is bad for the pastoralist. ‘Twas ever thus.
- Molecular characterization of olive (Olea europaea L.) Sicilian cultivars using SSR markers. Some things with the same name were different, some things with different names were the same. Still no cure for cancer.
- Characterization of Jordanian olive cultivars (Olea europaea L.) using RAPD and ISSR molecular markers. All the 13 tested were different. No word on relationships with the Sicilian varieties. But then I’ve given up on finding that sort of collaboration.
- Detection of Genome Donor Species of Neglected Tetraploid Crop Vigna reflexo-pilosa (Créole Bean), and Genetic Structure of Diploid Species Based on Newly Developed EST-SSR Markers from Azuki Bean (Vigna angularis). “V. trinervia and one taxon of V. hirtella are the genome donors of V. reflexo-pilosa.” Never heard of any of them.
Taro on display at SIDS meeting
The UN Conference on Small Island Developing States has just ended in Apia, Samoa. Lots of talk about partnerships for the sustainable development of these particularly vulnerable countries, although it’s unclear to me, as ever, how much of the money announced is actually new. Be that as it may, my old colleagues at SPC were very much involved, and took the opportunity of showcasing their work on the conservation and use of taro genetic resources in the poster reproduced here. An excellent example of the kind of partnerships made so much of in the media release.
Brainfood: Goat diversity, Sheep diversity, Camel keeping, Weird Zambian cattle, Pepper diversity, Strawberry diversity, Breeding wheat, Sustainable cacao, Food supply diversity
- The characterization of goat genetic diversity: Towards a genomic approach. A single Neolithic origin.
- Genome-wide patterns of adaptation to climate-mediated selective pressures in sheep. Adaptation to local climates has been important.
- Characterisation of camel breeding practices in the Ansongo Region, Mali. Diversity of practices, diversity of breeds.
- Gynomimicry in the Dwarf Gwembe breed from Zambia. The males mimic the secondary sexual characters of females, presumably because they’ve been selected to do so.
- Evaluation of a diverse, worldwide collection of wild, cultivated and landrace peppers (Capsicum annuum) for resistance to Phytophthora fruit rot, genetic diversity and population structure. No completely resistant lines out of 177, 2 pretty good ones, the better ones confined to 2 of 4 genetic clusters.
- Evaluation of strawberry (Fragaria L.) genetic resources on resistance to Botrytis cinerea. Out of 107 accessions in the German national genebank, 5 were pretty good, 4 of them F. vesca.
- Redesigning the exploitation of wheat genetic resources. Allele mining is out, genome-wide selection is in.
- Making biodiversity-friendly cocoa pay: combining yield, certification and REDD for shade management. Even if you increase yields by 50%, that may not be enough to stop farmers converting from traditional agroforestry. Enter ecolabelling and REDD.
- Measuring nutritional diversity of national food supplies. Production diversity is a good predictor of dietary diversity, but only for low income countries; otherwise income and trade are better. Dietary diversity associated with key health outcomes.
Brainfood: Ethiopian wild veggies, Cold tolerant rice, Chickpea genomics, Improved tilapia, Wild cassava oil, Chinese horses, Chinese melon, Seed sampling, Tomato spp sequencing
- Wild and semi-wild leafy vegetables used by the Maale and Ari ethnic communities in southern Ethiopia. 30 of them.
- Collection and Conservation of Cold Adapted Indigenous Rice Landraces from Western Ghats, South India. 56 of them.
- Exploring Germplasm Diversity to Understand the Domestication Process in Cicer spp. Using SNP and DArT Markers. 3 populations among domesticated types; more diversity in the wilds.
- Genetically-Improved Tilapia Strains in Africa: Potential Benefits and Negative Impacts. Mean present value of introducing an improved strain to Ghana is 1% of GDP, but you could get same with better management. Both would of course be best.
- Diversity in oil content and fatty acid profile in seeds of wild cassava germplasm. Some species could be oil crops.
- The Study of Genetic Diversity and Phylogenetic Evolution in Indigenous Horses (Equus caballus) of Gansu. If I understand the abstract correctly, this suggests, among other things, that some local horse breeds can be traced back to Przewalski’s Horse, maybe.
- Microsatellite Diversity, Population Structure, and Core Collection Formation in Melon Germplasm. In China. Frankly not nearly as interesting as the horse story.
- Optimal sampling of seeds from plant populations for ex-situ conservation of genetic biodiversity, considering realistic population structure. 25–30 individuals per population from few but widely-spaced populations.
- Exploring genetic variation in the tomato (Solanum section Lycopersicon) clade by whole-genome sequencing. 20x more diversity in the wilds than the cultivated, correlated with habitat.
- Understanding Sustainable Diets: A Descriptive Analysis of the Determinants and Processes That Influence Diets and Their Impact on Health, Food Security, and Environmental Sustainability. The determinants of sustainability are agricultural, health, sociocultural, environmental and socioeconomic, and fiddling with one to improve it may screw up another.
- Anchoring durum wheat diversity in the reality of traditional agricultural systems: varieties, seed management, and farmers’ perception in two Moroccan regions. Farmers grow both improved varieties and landraces, the latter mainly for their quality characteristics.
- Unraveling the nexus between water and food security in Latin America and the Caribbean: regional and global implications. Production has increased, but at the cost of the natural capital of the region, and nutritional problems persist.
Conserving horticultural species, one at the time
Another report from one of our correspondents at the International Horticultural Congress in Brisbane, this on the symposium on Utilization of Plant Genetic Resources:
The full day symposium keynote by Dr Ehsan Dulloo of Bioversity International covered the broad topic of developing strategies for conserving plant genetic diversity. Individual presentations covered a wide range of topics and crops, including: roots/tubers (sweet potatoes, yams, cassava), aroids and breadfruit in the Pacific Islands; use of native species to restore costal landscapes impacted by cyclones in Fiji; conservation of wild temperate small fruit species such as Vaccinium in Canada (blueberries and cranberries); use of the underutilized tea tree (Melaleuca alternifolia) in Australia; conservation of mango landraces on-farm in India; characterizing the morphological and genetic diversity of baobab (Adansonia digitata) in Kenya; and the cryopreservation of clonal genetic material of apple, peach and nut trees (Juglans spp), among others. The common thread that ran though most of these presentations is that a lot of work still needs to be done to understand the genetic diversity that we have and the best way to conserve it (in situ & ex situ), such that it leads to optimal use of these important genetic resources.
There’s one more of these updates from IHC2014 in the pipeline, which we’ll probably put up tomorrow.
