Through research and plant breeding, manipulation of different plant genes and loci encoded by the DNA sequence of the plant chromosomes by various methods can be done to produce different or desired genotypes that result in different or desired phenotypes.
2 lut 2021 · This review discusses the features of cis-regulatory sequences in plants, technologies enabling their identification, characterization, and validation, their organization into functional cis-regulatory modules, their genomic distributions with respect to target genes, and the role of transposable elements in their evolution.
19 paź 2020 · But through genome-level mutations, such as polyploidy (or whole-genome duplication, WGD), plant genomes not only reflect history, they also drive it. Here we explore how studies of plant genomes reveal both the intricate evolutionary history of plants and the processes that shape plant diversity. 2 GENOMES AS SIGNATURES OF EVOLUTIONARY HISTORY
13 mar 2015 · The DNA in plant cells is found in the nucleus, the mitochondria and the chloroplasts. The latter two organelles are descendants of bacteria that were captured by a eukaryotic cell and have become endosymbionts. DNA is a coded set of instructions for making RNA.
The sequences that are translated into proteins that influence cell and plant growth are called genes. In corn, for example, the sucrose manufactured in the leaves through photosynthesis is transported through the phloem to the ear and into the developing seed or kernel.
13 paź 2008 · There are pretty obvious differences between plants and animals, but – at the chemical level – the cells of all plants and all animals contain DNA in the same shape – the famous “double helix”...
Two of the bases, collectively called purines — Adenine (A) and Guanine (G) — contain two rings of carbon atoms. The other two, collectively called pyrimidines — Cytosine (C) and Thymine (T) — have only one ring of carbon atoms.
