Genome-wide association analysis for emergence of deeply sown rice (Oryza sativa) reveals novel aus-specific phytohormone candidate genes for adaptation to dry-direct seeding in th... by Sakhale, S.A., Shailesh, Y., Clark, L.V., Likpa, A., Kumar, A., Sacks, E.

“…Dry direct-seeded rice (dry-DSR) is typically sown deeply to circumvent the need for irrigation, and thus seedling emergence is a crucial trait affecting plant stand and yield. To breed elite cultivars that use less water and are climate-resilient, an understanding of the genomic regions and underlying genes that confer emergence in deeply sown dry-DSR would be highly advantageous. …”

Decentralization and rural service delivery in Uganda by Bashaasha, Bernard, Mangheni, Margaret Najjingo, Nkonya, Ephraim M.

“…While as anticipated generally decentralization resulted in greater participation and control over service delivery and governance by local communities, local governments are still grappling with a range of challenges, namely, inadequate local financial resources and over-reliance on conditional central government grants; inability to attract and retain sufficient trained and experienced staff; corruption, nepotism, and elite capture. With regard to the specific services, while universal primary education (UPE) policy under the decentralization framework is credited with a dramatic increase in primary school enrollment, public primary education services are still dogged by concerns over financing, equity, quality, and the need for curriculum reform. …”
