Abstract:

Impatiens siangensis Gogoi, a new species, is described and illustrated from Arunachal Pradesh, India. The new species differs from I. marianae Hooker by the absence of white blotches on the upper leaf surface, flowers only partially purple, bracts ovate, glabrous, lateral sepals glabrous, dorsal petal glabrous, navicular, lower sepal with straight purple streaks and spur almost straight. The new species differs from I. porrecta Wallich in having stems, leaves, and floral parts glabrous, stems branched, flowers partially purple, lower sepal navicular with straight purple streaks and spur almos

Abstract:

A new species of Masdevallia genus is described here. Masdevallia purocafeana is immediately recognized by having conspicuously broad, echinate, and strongly reflexed lateral sepals. It is compared to Masdevallia alexandri but differs by having an oblong, shallowly concave, yellow-green dorsal sepal variegated with purple towards the apex, oblong petals light pink suffused with yellow and spotted with purple, and ovoid-ovate, reflexed light pink lip, dotted with pale light red.

Abstract:

Abstract In order to ascertain the role of anthocyanin content on the color and brightness of Hydrangea macrophylla sepals, anthocyanin contents of different colored sepals were measured for numerous commercial cultivars. Anthocyanin contents were primarily determined by extraction of the pigment, then measurement by differential spectrophotometry. Concentrations ranged from about 25 to over 400 μg delphinidin-3-glucoside per g of fresh sepal, with the magnitude roughly proportional to the perceived intensity of sepal coloration for that Hydrangea macrophylla cultivar. However, the anthocyanin

Abstract:

Acianthera sudae is newly described based on cultivated material from Brazil. It belongs to section Cryptophoranthae and differs from all others in this group by the larger flowers and sepals fused apically for more than half length, and a green-brown abaxial side of sepals with purple dots. Chromosome number (2n = 40) and genome size estimation (1C-value = 1.18 pg) is provided and its phylogenetic placement under the genus is supported with reconstruction of a molecular phylogeny using nuclear ribosomal ITS.

Abstract:

Owing to the high anthocyanin content, broccoli varieties with purple curds have become more popular in food inventories, while the genetic mechanisms of anthocyanin biosynthesis pathways remain largely unknown. We bred a pair of near-isogenic lines (NILs), GB767 and PB767, whose curds exhibited green and purple colors, respectively, due to the purple sepals of florets. RNA sequencing and widely targeted metabolic analyses were conducted. Compared with GB767, eighteen anthocyanin biosynthesis-related genes exhibited significantly higher expressions in PB767, and in turn, the expression level o

For demonstration purposes, six structural (developmental) stages were sampled and classified. The seral stages, listed in increasing age after harvesting are as follows: initial, regeneration, early immature, late immature, mature, and old growth. The results of numerical and tabular analyses suggested the presence of two major floristic groups (seral associations) of the above seral stages: (i) E

Passiflora edulis, the passion fruit native from Brazil, has several common names (such as sour passion fruit, yellow passion fruit, black passion fruit, and purple passion fruit), and presents a wide variability with the different rind colors of its fruits, which are very easy to notice. However, in 1932, Otto Degener suggested that the yellow passion fruit had its origin in Australia through breeding, calling it P. edulis forma flavicarpa, and that it could be distinguished by the color of the fruit, the deeper shade of purple of the corona, and the presence of glands on the sepals.
