Hormone-regulated defense and stress response networks contribute to heterosis in Arabidopsis F1 hybrids.
Plant hybrids are extensively used in agriculture to deliver increases in yields, yet the molecular basis of their superior performance (heterosis) is not well understood. Our transcriptome analysis of a number of Arabidopsis F1 hybrids identified changes to defense and stress response gene expression consistent with a reduction in basal defense levels. Given the reported antagonism between pla...
متن کاملHeterosis in hybrids within and between yeast species.
The performance of hybrids relative to their parents is an important factor in speciation research. We measured the growth of 46 Saccharomyces yeast F1 interspecific and intraspecific hybrids, relative to the growth of each of their parents, in pairwise competition assays. We found that the growth of a hybrid relative to the average of its parents, a measure of mid-parent heterosis, correlated ...
متن کاملExpression of Heterosis for Productive Traits in F1 Brinjal (Solanum melongena L.) Hybrids
The study was carried out to estimate magnitude of heterosis over better parent and standard check for some important characters in 15 crosses resulting from a half diallel mating design of 6 inbred lines of brinjal. Hybrid variety ‘Tarapuri’ was used as standard check. The parents and the hybrids were evaluated at the farm of Olericulture Division, HRC, BARI, during the winter season of 2008-2...
متن کاملComparative transcriptome analysis of flower heterosis in two soybean F1 hybrids by RNA-seq
Heterosis has been widely exploited as an approach to enhance crop traits during breeding. However, its underlying molecular genetic mechanisms remain unclear. Recent advances in RNA sequencing technology (RNA-seq) have provided an opportunity to conduct transcriptome profiling for heterosis studies. We used RNA-seq to analyze the flower transcriptomes of two F1 hybrid soybeans (HYBSOY-1 and HY...
متن کاملHETEROSIS AND QUALITATIVE ATTRIBUTES IN WINTER TOMATO (Solanum lycopersicum L.) HYBRIDS
An investigation was carried out at the Research Farm of Olericulture Division of Horticulture Research Centre of Bangladesh Agricultural Research Institute (BARI) to evaluate the heterotic performance in F1 generation of tomato. The hybrids showed significant variation in heterosis. The highest heterobeltiotic effects were observed in the cross P3 x P8 (-18.46%) for earliness, P1 x P6 (8.57 %)...
