Abstract:
... Fruit shape is a critical appearance quality in apple. Quantitative trait loci (QTLs) for apple fruit shape index (FSI) traits were previously mapped by our laboratory to linkage group 11 of the maternal parent in a cross population of ‘Jonathan’ × ‘Golden Delicious’ using simple sequence repeat markers. In this study, QTLs for fruit length, diameter, and FSI were identified again using a high-den ...

This study reports some characteristics of a temperature-sensitive genic male sterile (TGMS) in Brassica napus line, SP2S, which is a spontaneous mutation found in 2007. The fertility alteration in response to temperature was investigated under controlled env ...

Abstract:
... Erycina pusilla is considered a potential model organism for orchids, because of several advantageous features, such as short juvenile period, low chromosome number and all year round blooming. Two different chromosome numbers (2n = 10 and 2n = 12) are reported for E. pusilla, which suggests two cytotypes. To reveal the genome homology between these two cytotypes, we generated hybrids from the int ...

Nsa CMS results in defective pollen production due to S. arvensis mitochondrial gene failure/incompatibility in the anthers, requiring nuclear genes to restore fertility. From ultramicroscopic observation of anther sections, we concluded that the induction of sterility begi ...

Host plant resistance offers the most sustainable means of controlling this pest. A cluster of genes on chromosome 9 confers resistance, with Me1 providing protection against three nematode species: M. incognita, M. javanica and M. arenaria. We describe the development of a ...

The only disease management tool used is resistant varieties. In the last 30 years, “Rizor” and “Holly” (Rz1) resistances have been the most widely used. Despite the lack of information, a common origin for both types of resistance wa ...
