A typical example is the evolution of cotton (Gossypium spp.), which includes two diploid and two allotetraploid crops (Figure 1c). However, around 95% of worldwide natural fiber for cloth production is based on the allotetraploid species Gossypium hirsutum, also known as upland cotton [20,21...
DomesticationArchaeobotanyMaizeBeansSquashGrain amaranthsCottonChocolateOlmecMayaThe great pre-Columbian civilisations of Mesoamerica depended on domesticated plants, notably maize, beans, squashes, grain amaranths and fruits, including avocado, together with cotton for fibre. Domestication is difficult to ...
Domestication of plants, including selection of appropriate species and genetic changes, is one of the features of agriculture, but agriculture also requires knowledge beyond suitable genotypes (Janick, 2005), such as the planting, growing, protection, and harvest of the plants and the accurate ...
Many experiments have shown that biodiversity enhances ecosystem functioning. However, we have little understanding of how environmental heterogeneity shapes the effect of diversity on ecosystem functioning and to what extent this diversity effect is med
For example, the Intergovernmental Panel on Climate Change suggests that traditional knowledge of locally adapted farming strategies is a key resource for climate resilience (IPCC 2022). A number of traditional crop diversification strategies and crops that have decreased in use with the mechanization ...
Genetically modified organisms (GMOs) refer to biological organisms that have had some of their instructions (the genes) precisely engineered by humans. This differs in degree from the more general genetic modifications made through thousands of years of domestication....
Here, we analyze the functional regulation of a RAG transposon, ProtoRAG, in lancelet. We find that a specific interaction between the cis-acting element within the TIR sequences of ProtoRAG and a trans-acting factor, lancelet YY1-like (bbYY1), is important for the transcriptional regulation...
Give an example of a good scientific hypothesis and justify your answer. Answer the following question. What is herbicide and how are we hypothesizing how it works? 1. How is both the external and internal stimuli involved in doing t...
Light absorption maxima of intact leaves (for example, Chrysanthemum morifolium L.) are in the bands of 400–490 nm and 660–680 nm, which is close to maximum absorption bands of a chlorophyll extract – 420–460 nm and 640–660 nm, respectively [96]. However, growing different plant ...
Thus, how and why sex is maintained remain important fundamental questions. While the overwhelming majority of plants engage in sexual reproduction, most plants (with the exception of annuals) also engage in some form of asexual reproduction. There are two main types of asexual reproduction: ...
