Root Microbiota: Orchestrating Architecture-Smart Crops. [PDF]
Microb BiotechnolRoot‐associated microbiota play an important role in shaping crop architecture. The concept of “holobiont architecture” is proposed, in which plant architecture is dynamically fine‐tuned through synergistic plant–microbiome interactions. This framework offers novel avenues for breeding architecture‐smart crops with improved phenotypic plasticity and ...

Death of pastures syndrome: tissue changes in Urochloa hybrida cv. Mulato II and Urochloa brizantha cv. Marandu [PDF]
Brazilian Journal of Biology, 2017 Abstract The quality of forage production is a prerequisite to raising livestock. Therefore, income losses in this activity, primarily cattle raising, can result in the impossibility of economic activity. Through the qualitative and quantitative anatomical study of Urochloa hybrida cv. Mulato II and U. brizantha cv.
