The isolation and analysis of a soybean CO Homologue GmCOL10

The isolation and analysis of a soybean CO Homologue GmCOL10 The CONSTANS (CO) gene is a key regulator of the response to photoperiod in the model plant Arabidopsis thaliana, and its homologues are present in many plant species. We describe here the isolation of the CO homologue for zinc finger protein gene GmCOL10 (Glycine max CONSTANS-Like 10) from the soybean cultivar Kennong18. Sequence comparisons showed that the closest A. thaliana gene to GmCOL10 is COL5. The expression of GmCOL10 was regulated in a circadian manner, especially under short-day conditions. The expression of GmCOL10 was concentrated in vegetative organs, and in particular in the unifoliolates and cotyledons. An analysis of subcellular localization found GmCOL10 in the nucleus. Our data suggested that GmCOL10 was not related to the photoperiodic pathway of floral transition as Arabidopsis CO does. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals

Abstract

The CONSTANS (CO) gene is a key regulator of the response to photoperiod in the model plant Arabidopsis thaliana, and its homologues are present in many plant species. We describe here the isolation of the CO homologue for zinc finger protein gene GmCOL10 (Glycine max CONSTANS-Like 10) from the soybean cultivar Kennong18. Sequence comparisons showed that the closest A. thaliana gene to GmCOL10 is COL5. The expression of GmCOL10 was regulated in a circadian manner, especially under short-day conditions. The expression of GmCOL10 was concentrated in vegetative organs, and in particular in the unifoliolates and cotyledons. An analysis of subcellular localization found GmCOL10 in the nucleus. Our data suggested that GmCOL10 was not related to the photoperiodic pathway of floral transition as Arabidopsis CO does.
