The science and legacies of Ronald Phillips: A brief perspective. [PDF]

Plant Genome
Abstract Ronald Phillips, a maize geneticist, developed his career exploiting maize and the genetics of other species to help bring plant science into the era of molecular genetics. He was driven by belief in the value of service for the common good and in the value and importance of science for its own sake and for agriculture and food security, in ...

Genome-Wide Identification and Expression Analysis of Cytosine DNA Methyltransferase Genes Related to Somaclonal Variation in Pineapple (Ananas comosus L.)

Agronomy, 2022
DNA methylation plays an important role in somaclonal variation. Cytosine-5 DNA methyltransferases (C5-MTases) are crucial enzymes for maintaining the de novo genome DNA methylation status, and the gene family has been identified and characterized in ...

Indirect Shoot Regeneration Using 2,4-D Induces Somaclonal Variations in Cinchona officinalis

Floresta e Ambiente, 2021
Cinchona officinalis is an important species from the Andean cloud forest that has a low regeneration rate in natural populations. In vitro regeneration of C. officinalis has been successfully established but somaclonal variation was not evaluated.

Somaclonal variation as a tool for temperate fruit breeding

Acta Agriculturae Slovenica, 1999
Somaclonal variation involves all forms of phenotypic and genotypic variation generated by in vitro growth. It can provide useful genetic variation for plant improvement, especially in vegetatively propagated crops such as fruits.

RAPD Analysis to Detect Somaclonal Variation of Pineapple In Vitro Cultures during Micropropagation

Biotropia: The Southeast Asian Journal of Tropical Biology, 2016
Plant off-types still become a concern in pineapple micropropagation. Reliable methods are needed to detect and to reduce plant off-types. This research was conducted to confirm the occurrence of somaclonal variation during micropropagation, to know the ...
