“…Distinctive differences with genome size are seen between the Drosera and Drosophullum. Hanson et al (2001) also noted that Drosophullum was more able than Drosera to acquire both scarce water and phosphorus from the soil, supporting the hypothesis of genome size reduction in carnivorous plants.…”

“…From the perspective of environmental effect, Hanson et al (2001) already pointed out a mineral-poor environment regarding to the genome size reduction in carnivorous plants. It may impose pressure to reduce redundant phosphorus-rich nucleic acid such as non-essential repeated DNA sequences, and hence tend to minimize genome sizes.…”

ABSTRACT:A carnivorous plant lineage including the Droseraceae and its closely related family Drosophyllaceae shows wide range of chromosome size or genome size, whereas all other carnivorous families possess rather small in the genomes sizes. This study gives an overview of the genome size diversity in carnivorous plant families, and evolutional trend of chromosome differentiation especially in the Doroseraceae.

“…These findings augment the Introduction Achiote or Bixa orellana L. (locally known as 'achiote') is a perennial tree, native to the Neotropics (Arce 1999) and the only cultivated species in the Bixaceae family (Ambrósio Moreira et al 2015). This species has one of the lowest estimates for the amount DNA among angiosperms, 4C = 0.78 pg with 2n = 14 chromosomes (Hanson et al 2001;De Almeida et al 2006). Bixa orellana L. was domesticated in the Neotropics, although it is not clear where or from which wild populations, and there is evidence that Bixa urucurana Willd.…”

Functional polymorphism in lycopene beta-cyclase gene as a molecular marker to predict bixin production in Bixa orellana L. (achiote)

et al. 2016

Bixin is an apocarotenoid obtained from the seed aril of Bixa orellana L., a tropical plant known as achiote in Mexico. This compound is the second most commonly used natural colouring for food and pharmaceutical industries. B. orellana is an outcrossing species that displays high genetic variability. Recently, the colour traits of sexual organs were associated with the biosynthesis and accumulation of bixin in mature seeds. Herein, we describe a new approach for genotype-phenotype association by surveying lycopene beta-cyclase (Bob-LCY1) gene variation in sixteen achiote accessions divided into three groups according to contrasting traits, such as flower colour, fruit colour and bixin production. Using a combination of single-strand conformational polymorphism techniques and the sequencing of polymorphic bands, we identified several single-nucleotide polymorphisms that divided the accessions into three haplotypes. Surprisingly, we observed that these three haplotypes were consistent with the same three groups previously characterized by phenotypic traits. We derived a putative sequence for the Bob-LCY1 gene and surveyed the variations in this sequence. The heterozygosity of Bob-LCY1 alleles resulted in a higher bixin content, likely associated with heterosis for this metabolite.

“…Buddleja species exist with 38 (B. globosa), 76 (B. davidii) and even up to 228 chromosomes. Great variation in interspecific genome size was also reported (Moore 1960;Hanson et al 2001;Zonneveld et al 2005;Van Laere et al 2009). The high genetic variability in Buddleja presents considerable opportunities to develop novel cultivars through interspecific crosses.…”

To introduce yellow colour in the commercial Buddleja davidii (2n = 4x = 76) assortment, an interspecific breeding programme with B. globosa (2n = 2x = 38) was started. The first step was to perform chromosome doubling in B. globosa. Two of the obtained tetraploid B. globosa plants were subsequently used as male parent in interspecific crosses with the white flowering B. davidii cv. Nanhoensis Alba. In total 182 interspecific crosses were made and 18 F1 hybrids were obtained. Genome size measurements, chromosome counts and genomic in situ hybridisation (GISH) analysis proved the hybrid nature of most of the F1 hybrids. Plant morphology also expressed hybrid characteristics. F1 seedlings inherited the yellowish flower colour from B. globosa. As for many other woody ornamentals, the creation of hybrids through interspecific hybridisation along with polyploidisation offers new opportunities for breeding in Buddleja.
