An allopolyploid formation consists of the two processes of hybridisation and chromosome doubling. Hybridisation makes a different genome combined in the same cell, and genome "shock" and instability occur during this process, whereas chromosome doubling results in doubling and reconstructing the genome dosage. Recent studies have demonstrated that small(More)
Reciprocal hybrids showing different phenotypes have been well documented in previous studies, and many factors accounting for different phenotypes have been extensively investigated. However, less is known about whether the profiles of small RNAs differ between reciprocal hybrids and how these small RNAs affect gene expression and phenotypes. To better(More)
Grafting between tuber mustard and red cabbage produced a chimeric shoot apical meristem (SAM) of TTC, consisting of Layers I and II from Tuber mustard and Layer III from red Cabbage. Phenotypic variations, which mainly showed in leaf shape and SAM, were observed in selfed progenies GSn (GS = grafting-selfing, n = generations) of TTC. Here the heritability(More)
Small RNAs play an important role in maintaining the genome reconstruction and stability in the plant. However, little is known regarding the role of small RNAs during the process of wide hybridisation and chromosome doubling. Therefore, the changes in the small RNAs were assessed during the formation of an allodiploid (genome: AB) and its allotetraploid(More)
Tuber mustard (Brassica juncea (L.) Czern. et Coss. var. tumida Tsen et Lee) is an important vegetable crop with a characteristic of expanded stem that is edible. The underlying molecular mechanism of the stem expansion is not well understood. Here, we reported that a total of 51 differentially expressed fragments (DEFs) with three expression patterns(More)
