Genomics of Citrus: Answering Questions from a Research Article

This assignment analyzes a research article on the genomics of citrus. The student answers questions related to the paper, covering topics such as the relatedness network, heterozygosity, and admixture proportions within different citrus species. The questions address the purpose of the study, the author's conclusions, and the potential for further research. The student identifies the main findings of the research and discusses the implications of the study. The assignment explores the genetic diversity of citrus plants, the introgression of pummelos among mandarins, and the characteristics of citrons. The student also proposes further investigations to expand on the research findings.

Question 2
The chosen sentence is “The reduced heterozygosity of citrons, a mono-embryonic
species, is probably due to the cleistogamy of its flowers”. It means that Citrons plants have
special ability to self pollination or making fertilization of its female reproductive organ by its
own pollen. This ability reduces the probability of developing zygote or primitive offspring that
have different genotype or individual type of gene.
Question 3
The purpose of the paper was to analyse the genome sequences of dissimilar citrus to
characterise the diversity as well as development of citrus at the species level and identify citrus
admixtures and interspecific hybrids. The purpose was also to examine the network of
relatedness within mandarins and sweet orange and the introgression of pummelos among
mandarins for exploration of early stages of citrus domestication.
Question 4
The aim is well mentioned in the discussion section where the author graphically
analysed the genetic diversity of citrus plant while providing adequate quantitative and graphical
representation of admixtures and interspecific hybrids as well as the genotype network within
introgression of pummelos among mandarins. The article helps to explore all the possible and
correlated genotypes of citrus plant with Citrus relatedness network, Admixture proportion,
Genetic structure and their diversity.
Question 5

3ANSWERING QUESTION FROM A JOURNAL ARTICLE
The article helps to explore all the possible and correlated genotypes of citrus plant with
Citrus relatedness network, Admixture proportion, Genetic structure and their diversity. The
conclusion has made enough justification accumulated from the discussion. However, the
geographical diversity of various specific genotypes could be explained more to understand the
trends of admixtures and interspecific hybrids within citrus spices. In the conclusion section of
this paper, the author specifies all the specific findings briefly. However, the geographical
distribution of the citrus genotype is not mentioned adequately.

Question 7
If I had the lab equipments, I would examine the different types interspecific hybrids and
their geographical distribution with more details. The article helps to explore all the possible and
correlated genotypes of citrus plant with Citrus relatedness network, Admixture proportion,
Genetic structure and their diversity. I would try to find the interrelation between the trends of
admixtures and the introgression of pummelos among mandarins. It would help to have more in-
depth view on how the Citron has made a independent heliotype choice amongst other citrus
species.
