characterized (Koornneef et al. 1991, 1998b, Lee et al, 1993, Araki and Komeda 1993, Clarke and Dean 1994, Clarke et al. 1995, Eimert et al. 1995, Zagotta et al. 1992, Sung et al. 1992, Martinez-Zapater et al. 1994, Sanda and Amasino 1996a, Amasino 1996, Levy and Dean 1998). Although they caused similar mutant phenotypes, diflbrent late-flowering mutants characterized responded to environmental...
Late bolting after cold exposure is an economically important characteristic of radish (Raphanus sativus L.), an important Brassicaceae root vegetable crop. However, little information is available regarding the genes and pathways that govern flowering time in this species. We performed high-throughput RNA sequencing analysis to elucidate the molecular mechanisms that determine the differences ...
The present study was carried out to assess the status of various hormones responsible for the flower induction of Nagal, Lulu, and Khalas date palm varieties in UAE. The nonenzymatic antioxidant compounds and the antioxidant enzymatic activities at preflowering, flowering, and postflowering stages of the date palm varieties were quantified. The ABA and zeatin concentrations were found to be si...
Flowering is an essential stage of plant growth and development. The successful transition to flowering not only ensures the completion of plant life cycles, it also serves as the basis for the production of economically important seeds and fruits. CONSTANS (CO) and FLOWERING LOCUS T (FT) are two genes playing critical roles in flowering time control in Arabidopsis. Through homology-based cloni...
The floral regulators GIGANTEA (GI), CONSTANS (CO), and FLOWERING LOCUS T (FT) play key roles in the photoperiodic flowering responses of the long-day plant Arabidopsis thaliana. The GI-CO-FT pathway is highly conserved in plants. Here, we demonstrate that the circadian clock proteins LATE ELONGATED HYPOCOTYL (LHY) and CIRCADIAN CLOCK-ASSOCIATED1 (CCA1) not only repressed the floral transition ...
A late-flowering mutant was isolated from rice T-DNA-tagging lines. T-DNA had been integrated into the K-box region of Oryza sativa MADS50 (OsMADS50), which shares 50.6% amino acid identity with the Arabidopsis MADS-box gene SUPPRESSOR OF OVEREXPRESSION OF CO 1/AGAMOUS-LIKE 20 (SOC1/AGL20). While overexpression of OsMADS50 caused extremely early flowering at the callus stage, OsMADS50 RNAi plan...
The effect of the major flowering gene (PPD) on seed weight of chickpea was studied on 450 F3 families from reciprocal crosses between a small-seeded, early-flowering (ppd/ppd ) type and a largeseeded, late flowering (PPD/PPD) cultivar. F4 progeny tests were carried out to determine the PPD genotypes of each individual F3. The effects of the PPD gene and the polygenes on mean seed weight were b...
The Arabidopsis FLOWERING LOCUS C (FLC) gene encodes a MADS box protein that acts as a dose-dependent repressor of flowering. Mutants and ecotypes with elevated expression of FLC are late flowering and vernalization responsive. In this study we describe an early flowering mutant in the C24 ecotype, flc expressor (flx), that has reduced expression of FLC. FLX encodes a protein of unknown functio...
The shift in plants from vegetative growth to floral development is regulated by red-far-red light receptors (phytochromes) and blue-ultraviolet A light receptors (cryptochromes). A mutation in the Arabidopsis thaliana CRY2 gene encoding a blue-light receptor apoprotein (CRY2) is allelic to the late-flowering mutant, fha. Flowering in cry2/fha mutant plants is only incompletely responsive to ph...
