WebArabidopsis ABSCISIC ACID INSENSEITIVE3 (ABI3), FUSCA3 (FUS3) and LEAFY COTYLEDON1 (LEC1) encode key transcription factors that control seed maturation … WebThe Arabidopsis mutants abscisic acid insensitive3-5 (abi3-5) and leafy cotyledon1-3 (lec1-3) have impaired seed maturation and quickly lose seed viability. abi3-5 and lec1-3 were used as sensitized genetic backgrounds for the study of seed longevity.
To investigate whether LEC1 was mobilized from the endosperm to the embryo in the form of RNA or protein, we performed RT-qPCR analyses to determine if there was any LEC1-GFP mRNA in the embryos. First, we measured the relative expression of GFP in the homozygous PLL, PPL, PPg, and WT (negative … Meer weergeven To investigate if the expression of LEC1 in the endosperm was necessary for seed maturation, we generated seeds with unfertilized endosperms of lec1 genotype and fertilized … Meer weergeven To further investigate whether an exclusive expression of LEC1 in the endosperm can rescue lec1 seed defects, we employed two endosperm-specific promoters, proPHERES1 (pPHE)20,21 and … Meer weergeven To test whether the expression of LEC1 in the embryo was required for seed maturation, we generated seeds with haploid lec1 embryos and normal LEC1 endosperms by pollinating flowers of a haploid … Meer weergeven To decipher the initiation and the mode of action of the endosperm-expressed LEC1, we closely monitored GFP signals in the developing … Meer weergeven Web13 jul. 2024 · Additionally, the calli overexpressed with LhMIR397a could generate early cotyledons 21 days after induction, and the somatic embryo induction time was short compared with other genotypes.
