Modeling multiple phenotypes in wheat using data-driven genomic exploratory factor analysis and Bayesian network learning por Momen, Mehdi, Bhatta, Madhav, Hussain, Waseem, Yu, Haipeng, Morota, Gota

“…This study shows that data‐driven exploratory factor analysis can reveal smaller dimensional common latent phenotypes that are likely to give rise to numerous observed field phenotypes without relying on prior biological knowledge. The inferred genomic latent factor structure from the Bayesian network provides insights for plant breeding to simultaneously improve multiple traits, as an intervention on one trait will affect the values of focal phenotypes in an interrelated complex trait system.…”

Herbicide options for weed control in dry-seeded aromatic rice in India por Mahajan, Gulshan, Chauhan, Bhagirath S.

“…Weeds, however, are the main biological constraints to its success. A study comprising 12 treatments was conducted to evaluate the efficacy of PRE (pendimethalin and pyrazosulfuron) and POST herbicides (bispyribac, penoxsulam, and azimsulfuron) applied either alone or in a sequence for weed control in dry-seeded fine rice cv. …”

Designing sustainable large-scale industrial plantation landscapes: use of natural forest remnants and corridors to maintain biodiversity, retain environmental functions/services,... por Poulsen, J.

“…Potential short-term economic incentives and benefits include: minimizing plantation damage caused by wind throw, fire and insect pest attack (by functioning as windbreaks, firebreaks, and providing habitat for biological control organisms), protecting and maintaining water quality and supply to both the plantation stands and the people living there, providing resources such as beneficial plants, and other NTFPs, for those local people who live within and around the plantation landscape, and, decreasing the plantation establishment and maintenance cost. …”
