Phenotypic, genotypic, and environmental correlations between characters in onion segregate populations obtained under different generations
Authors: D.L.M. Machado, J. A. de Freitas, J.M.Q. Luz, G. M. Maciel, A.P.O. Nogueira and E. di Camillo
Onion (Allium cepa L.) is the third most valuable vegetable crop worldwide and the third most produced in Brazil. The knowledge of the nature and the value of the relationship between the traits of interest is very important, since it is possible to select a main trait, with low heritability or difficult measurement, obtaining..

Differential expression of dormancy-Associated genes in fastigiata and hypogaea peanut
Authors: M.F.C. Silva, C.R.C. Silva, L.M. Lima, JPC Ramos, and R.C. Santos
Seed dormancy is a temporary replacement state observed in some higher plants, which prevents germination under unfavorable conditions. In several species, dormancy process is triggered by hormonal factors, initiated by ABA and precursor enzymes. In this work, we investigated the relationship between dormancy and the expressio..

Genome-Wide Analysis of a Radiation-Induced Lesion Mimic Mutant in Rice
Authors: Zhuo Zhenga, Mingcheng Guoa,b, Lihua Wua, Huimin Suna
Lesion mimic mutations (LMMs) are very useful genetic tools in plants, however, it is difficult to uncover genome-wide mutations using traditional technology, the development of whole genome sequencing (WGS) provides a means by which to identify genome-wide LMMs. In this study, WGS was performed to reveal the molecular mechani..
