Seed development, especially the relevant regulatory mechanism and genetic network are of fundamental scientific interest. Seed development consists of the development of embryo and endosperm; and endosperm development of rice (model species of monocots) is closely related to grain yield and quality. Recent genetic studies, together with other approaches, including transcriptome and proteomics analysis, high-throughput sequencing (RNA-seq, ChIP-seq), revealed the crucial roles of genetic and epigenetic controls in rice endosperm development. Here we summarize and update the genetic networks involved in the regulation of endosperm initiation, cell cycle regulation, aleurone layer specification, starch synthesis, storage protein accumulation and endosperm size, and the interactions between embryo and endosperm.
The Kuk Early Agricultural World Heritage Site is Papua New Guinea’s first World Heritage Site, and as such there are added challenges around management, and increased pressure to establish a good process for future heritage sites in the country.
While melons were familiar in antiquity, they were grown mostly for use of the young fruits, which are similar in appearance and taste to cucumbers, C. sativus....Findings: Medieval lexicographies and an illustrated Arabic translation of Dioscorides' herbal suggest that sweet melons were present in Central Asia in the mid-9th century. A travelogue description indicates the presence of sweet melons in Khorasan and Persia by the mid-10th century. Agricultural literature from Andalusia documents the growing of sweet melons, evidently casabas (Inodorous Group), there by the second half of the 11th century, which probably arrived from Central Asia as a consequence of Islamic conquest, trade and agricultural development. Climate and geopolitical boundaries were the likely causes of the delay in the spread of sweet melons into the rest of Europe.
Call it irony, if you will, or call it a nightmare, but Big Oil evidently has no qualms about making its next set of profits directly off melting the planet. Its top executives continue to plan their futures (and so ours), knowing that their extremely profitable acts are destroying the very habitat, the very temperature range that for so long made life comfortable for humanity.
Their prior knowledge of the damage they are doing is what should make this a criminal activity. And there are corporate precedents for this, even if on a smaller scale. The lead industry, the asbestos industry, and the tobacco companies all knew the dangers of their products, made efforts to suppress the information or instill doubt about it even as they promoted the glories of what they made, and went right on producing and selling while others suffered and died.... http://www.commondreams.org/view/2013/05/23-4

Illegal logging and unchecked economic development are taking a devastating toll on the forests of Vietnam and neighboring countries, threatening areas of biodiversity so rich that 1,700 species have been discovered in the last 15 years alone.
Posting photos by Gabriele Galmimberti of "Grandmothers from around the Globe" got me thinking about hospitatlity and sharing... then and now. New forms of hospitality are emerging and maybe our focus has shifted somehwat but its worth some thought as to the implications for Bio-cultural diversity and what we are learning from new forms of engagement.

Economic Botany 2012: A cache of sesame (Sesamum indicum L.) seeds, discovered in the Thousand Buddha Grottoes at Boziklik, Turpan, China, dating to ca. 700 years before present (BP), is hard evidence of their use in China since that time. Morphological and anatomical features suggest a white sesame cultivar. The sizeable quantity unearthed implies that sesame was a valued commodity that could provision the monks and enrich the diet of ancient inhabitants as an oil source.
Manna grass (mainly but not exclusively G. fluitans) used to be widely gathered in most lowland areas of the present territory of Poland and western and southern Belarus. It had an important function as a component of tribute paid to local landowners by villagers, which led to the persistence of manna gathering even when this was not sustainable for peasants themselves. Manna grass was always an expensive food due to its time consuming gathering, but appreciated for its sweet taste and often served as dessert. In the nineteenth century marshes shrank significantly and the payment of tribute disappeared from the local economy, which gradually led to the total abandonment of Glyceria use around 1914. This article provides a detailed overview of Glyceria use as food within the borders of the former Polish-Lithuanian Kingdom (now Poland, Lithuania, western Belarus and western Ukraine) based on archaeobotanical, historical and ethnographic sources. The evidence for the continued use of manna since at least medieval times is abundant in historical accounts and ethnographic studies, but little has been reported in archaeobotanical findings due to the relatively small amounts of Glyceria consumed.
