Flowering time plays a significant role in the reproductive success of plants. So far, five major pathways to flowering have been characterized in Arabidopsis, including environmental induction through photoperiod, vernalization, and gibberellins and autonomous floral iation, and aging by sequentially operating miRNAs (typically miR156 and miR172)(More)
After several years in the juvenile phase, trees undergo flowering transition to become mature (florally competent) trees. This transition depends on the balanced expression of a complex network of genes that is regulated by both endogenous and environmental factors. However, relatively little is known about the molecular processes regulating flowering(More)
To identify novel as well as conserved miRNAs in citrus, deep sequencing of small RNA library combined with microarray was performed in precocious trifoliate orange (an early flowering mutant of trifoliate orange, Poncirus trifoliata L. Raf.), resulting in the obtainment of a total of 114 conserved miRNAs belonging to 38 families and 155 novel miRNAs. The(More)
To isolate differentially expressed genes during the juvenile-to-adult phase transition of an early-flowering trifoliate orange mutant (precocious trifoliate orange, Poncirus trifoliata), suppression subtractive hybridization was performed. In total, 463 cDNA clones chosen by differential screening of 1,920 clones were sequenced and 178 differentially(More)
Most of what we know about the molecular genetics of flowering time regulation comes from studies in the model plants. However, little is known about the regulation of flowering transition in perennial species or in species with particular growth habits compared with model plants. Here comparative transcriptome and proteome profiling of spring shoots was(More)
MicroRNAs (miRNAs) are a new class of small, endogenous RNAs that play a regulatory role in various biological and metabolic processes by negatively affecting gene expression at the post-transcriptional level. While the number of known Arabidopsis and rice miRNAs is continuously increasing, information regarding miRNAs from woody plants such as citrus(More)
Citrus shoot tips abscise at an anatomically distinct abscission zone (AZ) that separates the top part of the shoots into basal and apical portions (citrus self-pruning). Cell separation occurs only at the AZ, which suggests its cells have distinctive molecular regulation. Although several studies have looked into the morphological aspects of self-pruning(More)
An Improved Ant Colony Optimization (IACO) algorithm is proposed to the Flexible Job Shop Scheduling Problem (FJSSP) in this paper. IACO algorithm provides an effective integration between Ant Colony Optimization (ACO) model and knowledge model. In the IACO algorithm, knowledge model learns some available knowledge from the optimization of ACO, and then(More)
The transition to flowering is a major developmental switch in flowering plants. The nuclear RNA-binding protein FCA responds to seasonal signals and abscisic acid (ABA), which can control the flowering time via ambient temperature and autonomous pathways. Citrus FCA ortholog (PtFCA) has been isolated and characterized from precocious trifoliate orange(More)
