Comparing fresh root yield and quality of certified and farmer-saved cassava seed por Yabeja, J. W., Manoko, M. L. K., Legg, J.

“…Questions remain, however, about the value of certified cassava seed when compared to seed which is recycled multiple times, which is standard farmer practice. A study was therefore conducted to compare fresh cassava root yields of high-quality seed (HQS) versus farmer-saved (recycled) seed (FSS) for three widely grown improved cassava varieties in Tanzania namely: Mkuranga1, Kiroba and Mkombozi. …”

Genome wide analysis of NLP transcription factors reveals their role in nitrogen stress tolerance of rice por Jagadhesan, B., Sathee, Lekshmy, Meena, Hari S., Jha, Shailendra K., Chinnusamy, Viswanathan, Kumar, Arvind, Kumar, Santosh

“…The results showed that high NUE rice genotypes has both high Nitrogen uptake efficiency (NUpE) and Nitrogen utilization efficiency (NUtE), resulting from the effective and coordinated signal transduction network involving the rice homologue of nitrate transceptor OsNRT1.1B, the probable primary nitrate response (PNR) regulator OsNLP1 and the master response regulator OsNLP3, a homologue of AtNLP6/7.…”
