The development of maize seed markets in Sub-Saharan Africa por Rusike, Joseph

“…The study provides evidence that seed industry development is an evolutionary learning-by-doing process of fitting together a set of interactive and mutually supporting institutions in a path dependent way that hold down transaction and production costs and infuse trading confidence in seed transactions. …”

Women's land rights in the transition to individualized ownership: implications for tree resource management in Western Ghana por Quisumbing, Agnes R., Payongayong, Ellen, Aidoo, J. B., Otsuka, Keijiro

“…Based on a survey of 60 villages in Western Ghana, where cocoa is the dominant crop, this study explores evolutionary changes in land tenure institutions on women's land rights and the efficiency of tree resource management....With increasing population pressure, customary land tenure institutions in Western Ghana have evolved toward individualized systems in order to provide appropriate incentives to invest in tree planting and management. …”

Early inflorescence and floral development in Cocos nucifera L. (Arecaceae: Arecoideae) por Perera, Prasanthi I.P., Hocher, V, Weerakoon, LK, Yakandawala, D.M.D., Fernando, SC, Verdeil, JL

“…The flowering behaviour of palm species may be a useful indicator of phylogenetic relationships and therefore evolutionary events. This paper presents a detailed histological study of reproductive development in coconut (Cocos nucifera L.), from initiation up to maturation of staminate and pistillate flowers. …”

The genome of cultivated sweet potato contains Agrobacterium T-DNAs with expressed genes: An example of a naturally transgenic food crop por Kyndt, Tina, Quispe, D., Zhai, H., Jarret, Robert L., Ghislain, M., Liu, Q., Gheysen, G., Kreuze, Jan F.

“…These sequences, which are shown to be expressed in a cultivated sweet potato clone (“Huachano”) that was analyzed in detail, suggest that an Agrobacterium infection occurred in evolutionary times. One of the T-DNAs is apparently present in all cultivated sweet potato clones, but not in the crop’s closely related wild relatives, suggesting the T-DNA provided a trait or traits that were selected for during domestication. …”

Comparative genomics of gene families in relation with metabolic pathways for gene candidates highlighting por Larivière, D., Couvin, D., Droc, Gaëtan, Lorenzo, G., Guignon, Valentin, Rouard, M., Lyons, E., This, D., Bocs, S., Dufayard, Jean-François

“…The study of gene families is an important field of comparative genomics, allowing, by the analysis of evolutionary history, to identify homology relationships, gene losses and to help in annotation transfers. …”

Comparative and functional genomics of closteroviruses por Dolja, V.V., Kreuze, Jan F., Valkonen, J.P.T.

“…Proteins encoded by these genes include suppressors of RNA silencing, RNAse III, papain-like proteases, the AlkB domain implicated in RNA repair, Zn-ribbon-containing protein, and a variety of proteins with no detectable homologues in the current databases. The evolutionary processes that have shaped the complex and fluid genomes of the large RNA viruses might be similar to those that have been involved in evolution of genomic complexity in other divisions of life.…”

Elucidating mechanisms underlying organ abscission por Estornell, Leandro H., Agustí, Javier, Merelo, Paz, Talón, Manuel, Tadeo, Francisco R.

“…Abscission consists in the detachment of entire vegetative and reproductive organs due to cell separation processes occurring at the abscission zones (AZs) at specific positions of the plant body. From an evolutionary point of view, abscission is a highly advantageous process resulting into fruit and seed dispersal as well as the shedding of no longer useful organs. …”
