Vascular related NAC (NAM, ATAF and CUC) domain-containing genes regulate secondary wall deposition and differentiation of xylem vessel elements. MusaVND1 is an ortholog of Arabidopsis VND1 and contains the highly conserved NAC domain. The expression of MusaVND1 is highest in developing corm and during lignification conditions, the increase in expression of(More)
NAM, ATAF, and CUC (NAC) domain-containing proteins are plant-specific transcription factors involved in stress responses and developmental regulation. MusaVND2 and MusaVND3 are vascular-related NAC domain-containing genes encoding for nuclear-localized proteins. The transcript level of MusaVND2 and MusaVND3 are gradually induced after induction of(More)
NAC (NAM, ATAF and CUC) proteins are plant-specific transcription factors regulating development and responses to stress. One of NAC proteins from banana is NAC68, and expression analysis indicated its positive association to stress conditions. The 5′-proximal region of MusaNAC68 was isolated and sequence analysis indicated presence of stress related(More)
Introduction The nucleolus is the most prominent subnuclear structure in the eukaryotic nucleus, whose primary responsibility has traditionally been ribosome biogenesis (Olson, 2004a). Apart from this conventional role, the nucleolus has been implicated in such diverse functions as a stress sensor (Rubbi and Milner, 2003; Olson, 2004b), signal recognition(More)
Tracheary elements formation was observed in banana embryogenic cells cultured in brassinolide-supplemented medium after a period of 10 days. The highest frequency of tracheary elements observed after 10 days was up to 31.88 %. The auxin, 2,4-D was found to be inhibitor of tracheary elements formation in brassinolide-supplemented medium and at a(More)
Banana is an important fruit crop and its yield is hampered by multiple abiotic stress conditions encountered during its growth. The NAC (NAM, ATAF, and CUC) transcription factors are involved in plant response to biotic and abiotic stresses. In the present study, we studied the induction of banana NAC042 transcription factor in drought and high salinity(More)
Lignin and polyphenols are important cellular components biosynthesized through phenylpropanoid pathway. Phenylpropanoid pathway in plants is regulated by some important transcription factors including R2R3 MYB transcription factors. In this study, we report the cloning and functional characterization of a banana R2R3-MYB transcription factor (MusaMYB31) by(More)
