“…By combining mathematical modeling with a geographic information system in a spatiotemporal projection as we do in this study, the field implementation of microbial control against locust in an integrated pest management system may be improved. Finally, the practical utility of this model provides insights that may improve the timing of pesticide application in a selected area where efficacy is highly expected.…”

CTP synthase is essential for early endosperm development by regulating nuclei spacing por Yoon, Jinmi, Cho, Lae-Hyeon, Kim, Sung-Ryul, Tun, Win, Peng, Xin, Pasriga, Richa, Moon, Sunok, Hong, Woo-Jong, Ji, Hyeonso, Jung, Ki-Hong, Jeon, Jong-Seong, An, Gynheung

“…OsCTPS1 transiently formed macromolecular structures in the endosperm during early developmental stages, further supporting the idea that OsCTPS1 may function as a structural component during endosperm development. Finally, overexpression of OsCTPS1 increased seed weight by promoting endosperm nuclear division, suggesting that this trait could be used to increase grain yield.…”

The potential of rice to offer solutions for malnutrition and chronic diseases por Dipti, Sharifa Sultana, Bergman, Christine, Indrasari, Siti Dewi, Herath, Theja, Hall, Robert, Lee, Hueihong, Habibi, Fatemeh, Bassinello, Priscila Zaczuk, Graterol, Eduardo, Ferraz, Julie P., Fitzgerald, Melissa

“…We discuss how rice might offer sometimes even simple solutions to rectifying key problems through targeted biofortification strategies and finally, we draw attention to how recent technological (−omics) developments may facilitate untold new opportunities for more rapidly generating improved rice varieties specifically designed to meet the current and future nutritional needs of a rapidly expanding global population.…”

Functional characteristics of an endophyte community colonizing rice roots as revealed by metagenomic analysis por Sessitsch, A., Hardoim, P., Döring, J., Weilharter, A., Krause, A., Woyke, T., Mitter, B., Hauberg-Lotte, L., Friedrich, F., Rahalkar, M., Hurek, T., Sarkar, A., Bodrossy, L., van Overbeek, L., Brar, D., van Elsas, J.D., Reinhold-Hurek, B.

“…Surprisingly, endophytes might be involved in the entire nitrogen cycle, as protein domains involved in N2-fixation, denitrification, and nitrification were detected and selected genes expressed. …”

Migration, isolation and hybridization in island crop populations: the case of Madagascar rice por Mather, Kristie A., Molina, Jeanmaire, Flowers, Jonathan M., Rubinstein, Samara, Rauh, Brad L., LAWTON-RAUH, AMY, Caicedo, Ana L., McNally, Kenneth L., Purugganan, Michael D.

“…We also found a high frequency of a unique indica type in Madagascar that shows clear population differentiation from most of the sampled Asian landraces, as well as differential exchange of alleles between Asia and Madagascar populations of the tropical japonica subspecies. Finally, despite partial reproductive isolation between japonica and indica, there was evidence of indica/japonica recombination resulting from their hybridization on the island.…”

Malawi: Systematic analysis of domestic production and world market shocks por Mukashov, Askar, Duchoslav, Jan, Kankwamba, Henry, Jones, Eleanor, Thurlow, James

“…Rural low-income households’ consumption and poverty are exposed to a wide range of risks, including production volatility of livestock, yield volatility of oilseeds, cereals, vegetables and world market price of beverage crops. Finally, for undernourishment outcomes, volatility in the yields of staple cereals is the dominant risk factor for all household types. …”

IBD sharing patterns as intra-breed admixture indicators in small ruminants por Da Silva, Stéphane, Mwacharo, Joram, Li, Meng-Hua, Ahbara, Abulgasim, Catherine Muchadeyi, Farai, Dzomba, Edgar, Lenstra, Johannes, Silva, Anne da

“…These results pave the way for further research that could lead to the development of admixture indicators, based on the characterization of intra-breed shared IBD segments, particularly effective as they would be independent of the knowledge of the whole genetic landscape in which the breeds evolve. Finally, by highlighting the fragmentation experienced by the genomes subjected to crossbreeding carried out over the last few generations, the study reminds us of the need to preserve local breeds and the integrity of their adaptive architectures that have been shaped over the centuries.…”

Top-down vs bottom-up processes: A systematic review clarifying roles and patterns of interactions in food system transformation por Conti, Costanza, Hall, Andy, Moallemi, Enayat A., Laila, Amar, Bene, Christophe, Fanzo, Jessica, Gibson, Matthew Ford, Gordon, Line, Hicks, Christina, Kok, Kristiaan, Rao, Nitya, Laxminarayan, Ramanan, Mason-D'Croz, Daniel

“…We suggest a shift from dichotomic views on top-down and bottom-up actor roles towards the concept of “transformation functions,” which would re-centre the discussion around the existing or needed capabilities for transformation in different contexts. Finally, we call for further research to determine how different transformation functions need to become more synchronised -or coordinated-to accelerate transformation.…”
