“…1j-l). The increase or decrease in number of secondary chromosomes might be attributed to duplication of such chromosome or translocation between the chromosomes with or without secondary constrictions at a very early stage of evolution (Mukhopadhyay and Sharma 1987, Mukhopadhyay and Ray 2013, Kumari et al 2014) All these findings clearly indicated the role of cryptic structural alterations of chromosomes in the evolution of these varieties (Mukhopadhyay and Sharma 1987, Lahiri et al 2010, Samanta et al 2015. The data on chromosomal parameters for each sample were obtained after examining ten cells at metaphase stages.…”

SummaryThe present article has reported a detailed karyotype analysis and 4C nuclear DNA estimation in different cultivars and populations of Clitoria ternatea L. of Fabaceae. This plant, widely distributed in tropical regions in India, is a climber and is an economically important medicinal plant. The karyotype study has revealed a constancy in the diploid somatic chromosome number (2n=16) in all these cultivars and populations. However, the nature and number of nucleolar chromosomes varied. The centromeric chromosomes were either metacentric or sub-metacentric in all these cultivars. The total chromosome length and volume differed among these cultivars and populations having the same somatic chromosome number. The differential condensation of chromosomes and the association of variable amounts of proteins in chromosome composition might have been responsible for such differences. In situ cytophotometric studies revealed an intermediate genome size in this species. This is the first report on the detailed karyotype and genome size of cultivars of Clitoria ternatea L.

“…Leaves of C. makoyana have lobed, dark-green (DG) regions extending from the mid vein, which sometimes merge with the DG margin [ 3 ]. However, C. insignis leaves are narrow, tapering, stiffly erect foliage with wavy margins, and look yellowish-green with alternating lateral large and small oval patches, with DG markings on the upper surface and a dark, purplish-red lower surface [ 4 ]. Moreover, C. insignis is an important source of nutrition, as it is known for the high quality of starch in its tubers and roots [ 5 ] and it is rich in both macro- and micronutrients [ 6 ].…”

Plants of the genus Calathea possess many leaf colors, and they are economically important because they are widely used as ornamentals for interior landscaping. Physiological performances and photosynthetic capacities of C. insignis and C. makoyana were investigated. The photosynthetic efficiencies of C. insignis and C. makoyana were significantly increased when the photosynthetic photon flux density (PPFD) increased from 0 to 600 μmol photons·m−2·s−1 and became saturated with a further increase in the PPFD. The two Calathea species had lower values of both the light saturation point and maximal photosynthetic rate, which indicated that they are shade plants. No significant differences in predawn Fv/Fm values (close to 0.8) were observed between dark-green (DG) and light-green (LG) leaf sectors in all tested leaves. However, the effective quantum yield of photosystem II largely decreased as the PPFD increased. An increase in the apparent photosynthetic electron transport rate was observed in both species to a maximum at 600 μmol·m−2·s−1 PPFD, following by a decrease to 1500 μmol·m−2·s−1 PPFD. Compared to LG leaf extracts, DG leaf extracts contained higher levels of chlorophyll (Chl) a, Chl b, Chls a + b, carotenoids (Cars), anthocyanins (Ants), flavonoids (Flas), and polyphenols (PPs) in all plants, except for the Ant, Fla and PP contents of C. insignis plants. Calathea insignis also contained significantly higher levels of total protein than did C. makoyana. The adjusted normalized difference vegetation index (NDVI), photochemical reflectance index (PRI), red-green, and flavonol index (FlavI) were significantly correlated to leaf Chls a + b, Cars, Ants, and Flas in C. makoyana, respectively, and can be used as indicators to characterize the physiology of these plants.
