S., Niranjani, G., Jagadeeshwar, R.

“…Changes in the virulence pattern of BPHacross the regions and breakdown of resistance in many released resistant cultivars warrant identification of novel and diverse germplasm resources that can be deployed for developing new rice varieties with a broader genetic base. Accordingly, the field phenotypic screening was conducted over two years during kharif 2020 and 2021 using 300 rice genotypes (selected from 3 K subset of BPH panel) along with eight checks in an augmented block design to identify the BPH-resistant donor lines. …”

Emerging infectious diseases : using PCV2 as a model of disease transmission dynamics at the livestock-wildlife interface in Uganda por Jonsson, L.

“…PCV2 is, in this study, used as a model for disease transmission dynamics because it is spread among pigs throughout the world, has some genetic variation and has been found in both domestic and wild pigs.The aims of this study were to investigate the disease transmission dynamics in the livestock- wildlife interface in Uganda with PCV2 as a model, as a part of the EID surveillance, and to estimate the prevalence of PCV2 in domestic pigs in Uganda.Ninety-one domestic pigs around Murchison Falls national park were sampled and analyzed with SybrGreen RT-PCR for three different PCV2 genogroups, SG1, SG2 and SG3. …”

Potential for biological nitrification inhibition (BNI) to reduce nitrification and N2O emissions from pasture-crop-livestock systems por Subbaraoa, Guntur V., Rao, Idupulapati M., Nakahara, K., Sahrawat, Kanwar Lal, Hash, C.T., Ando, Yasuo, Kawashima, T.

“…Here we present the current status of our understanding on how the BNI functions in Brachiaria pastures and feed-grain crops such as sorghum can be exploited both genetically and, from a production system's perspective, to develop low-nitrifying and low N2O-emitting production systems that would be economically profitable and ecologically sustainable.…”

A framework for analyzing participatory plant breeding approaches and results por Sperling, L., Ashby, Jacqueline A., Smith, M.E., Weltzien, Eva, McGrath, S.

“…While some have argued that commercial, private sector plant breeding has long been client-driven, or `participatory' under another name, the application of `PPB' to reach poor client groups, to breed for high-stress, heterogeneous environments and to incorporate diverse traits to meet specific client preferences is resulting in fundamental changes in the way plant genetic resources are being managed. PPB merits analysis as a separate approach. …”
