4 days ago · Maize / m eɪ z / (Zea mays), also known as corn in North American and Australian English, is a tall stout grass that produces cereal grain. It was domesticated by indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte. Native Americans planted it alongside beans and squashes in the Three Sisters polyculture.
1 day ago · While maize, potatoes, and chili peppers became important globally in the 16th and 17th centuries as part of the Columbian Exchange, llamas/alpacas and quinoa have only gained worldwide prominence in the 20th and 21st centuries.Unraveling the history of how, where, when, and why these species were domesticated requires the expertise of researchers in the fields of biology, genetics, and ...
3 days ago · Grain filling in maize (Zea mays) is intricately linked to cell development, involving the regulation of genes responsible for the biosynthesis of storage reserves (starch, proteins, and lipids) and phytohormones.However, the regulatory network coordinating these biological functions remains unclear. In this study, we identified 1744 high-confidence target genes co-regulated by the ...
3 days ago · The average proportion of epistatic variance in maize, yeast, and mice was estimated to be 2% , 3 to 5% (19, 33), and 1.6 to 1.8% , respectively. Therefore, the epistatic variance in rice is similar to that found in other model organisms.
1 day ago · Background and Aim Continuous monocropping with high nitrogen (N) fertilizer input substantially increases greenhouse gas (GHG) emissions in maize-based agroecosystems in the North China Plain (NCP). Introducing soybeans as an intercrop with maize and partially substituting urea with manure might effectively decrease GHG emissions. The aim of this study was to quantify the synergistic effect ...
3 days ago · 1 Introduction. In the past few decades, the increase in maize yield per unit area has primarily been attributed to higher planting density, rather than an enhancement in yield potential per plant (Sun et al., 2023).Maize have been adapted for high-density planting, however, high-density planting often makes plants susceptible to lodging, and reduce the yield.
1 day ago · Based on a greenhouse experiment we considered plasticity in two maize traits: root-to-leaf biomass allocation ratio and emergence rate of axial roots. In a simulation experiment we individually enabled or disabled both plastic responses for maize stands grown across six N levels.
