Abstract:
... Rain-fed agriculture is threatened by an increased frequency of droughts worldwide thereby putting millions of livelihoods at risk especially in sub-Saharan Africa. This makes drought preparedness critical. In this study, we sought to establish whether maize yield can be predicted using the number of dry dekads that occur at specific maize growth stages for purposes of yield early warning. The dry ...

Abstract:
... BACKGROUND: The genome-wide expression profile of genes in different tissues/cell types and developmental stages is a vital component of many functional genomic studies. Transcriptome data obtained by RNA-sequencing (RNA-Seq) is often deposited in public databases that are made available via data portals. Data visualization is one of the first steps in assessment and hypothesis generation. However ...

Abstract:
... Setaria viridis is being promoted as a model C₄ photosynthetic plant because it has a small genome (~515 Mb), a short life cycle (~60 d) and it can be transformed. Unlike other C₄ grasses such as maize, however, there is very little information about how C₄ leaf anatomy (Kranz anatomy) develops in S. viridis. As a foundation for future developmental genetic studies, we provide an anatomical and ul ...

Abstract:
... Maize, Zea mays, the second-most-widely-grown crop, yields 20 % of all consumed calories worldwide.¹ Despite its agronomic importance, research progress is limited by costly transformation. We recently described the Trojan horse method as a useful tool to study maize proteins in situ that circumvents time- and space-consuming whole plant transformation. The Trojan horse approach uses the protein-f ...

Abstract:
... Post‐transcriptional gene silencing in plants results from independent activities of diverse small RNA types. In anthers of grasses, hundreds of loci yield noncoding RNAs that are processed into 21‐ and 24‐nucleotide (nt) phased small interfering RNAs (phasiRNAs); these are triggered by miR2118 and miR2275. We characterized these ‘reproductive phasiRNAs’ from rice (Oryza sativa) panicles and anthe ...
