Morphological, Physiological, and Molecular Responses of Sweetly Fragrant During the Floral Transition Stage Induced by Short-Day Photoperiod.

Photoperiod-regulated floral transition is vital to the flowering plant. "Xiangfei" is a flowering ornamental plant with high development potential economically and is a short-day woody perennial. However, the genetic regulation of short-day-induced floral transition in is unclear.

Chromosome-level genome assembly and population genetic analysis of a critically endangered rhododendron provide insights into its conservation.

Rhododendrons are woody plants, famous throughout the world as having high horticultural value. However, many wild species are currently threatened with extinction. Here, we report for the first time a high-quality, chromosome-level genome of Rhododendron griersonianum, which has contributed to approximately 10% of all horticultural rhododendron varieties but which in its wild form has been evaluated as critically endangered.

Genetic Diversity of From Two Different Climate Type Areas.

L. is a well-known medicinal and edible plant species. Various medicinal compounds in the fruit make it an important medicinal and promising economic material.

Development of novel EST-SSR markers for (Phyllanthaceae) and cross-amplification in two related species.

Premise Of The Study: A novel set of EST-SSR markers was developed for (Phyllanthaceae) to investigate the genetic structure and gene flow, identify novel genes of interest, and develop markers for assisted breeding.

Methods And Results: Based on the transcriptome data of , 83 EST-SSR primer pairs were designed; 52 primer pairs were successfully amplified, with 20 showing polymorphisms in 90 individuals from three populations of . The number of alleles per locus varied from 11 to 44.

Development of novel EST-SSR markers for (Ericaceae) and cross-amplification in two congeners.

Premise Of The Study: To investigate the genetic background and population characteristics of (Ericaceae), a newly discovered and critically endangered species, expressed sequence tag-simple sequence repeat markers were developed, and transferability was tested in two congeners, and .

Methods And Results: Based on the transcriptome sequences of , 102 primer sets were designed; 48 primer sets were successfully amplified, with 15 showing polymorphisms in 150 individuals from five extant populations of . The number of alleles per locus ranged from four to 18, and the levels of observed and expected heterozygosity for the 15 loci varied from 0.

Study on Reproductive Biology of : A Newly Discovered and Special Threatened Plant Surviving in Limestone Habitat in Southeast Yunnan, China.

is a narrow endemic species and a subject of urgent demand in the domestic market and overseas. Its fascinating shapes, brilliantly gilvous flowers, and unusual flowering time endow this species with extremely high ornamental value. However, only five wild populations of surviving in limestone habitat have been found through elaborate field investigation, and the number of the populations decreases further or is even confronted with risk of extinction due to the damage of human activities.

Floral Scent Chemistry of Luculia yunnanensis (Rubiaceae), a Species Endemic to China with Sweetly Fragrant Flowers.

plants are famed ornamentals with sweetly fragrant flowers. Hu is an endemic plant from Yunnan Province, China. Headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) was used to identify the volatile organic compounds (VOCs) of the different flower development stages of for the evaluation of floral volatile polymorphism.

Volatile Organic Compounds Emissions from Luculia pinceana Flower and Its Changes at Different Stages of Flower Development.

Luculia plants are famed ornamental plants with sweetly fragrant flowers, of which L. pinceana Hooker, found primarily in Yunnan Province, China, has the widest distribution. Solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) was employed to identify the volatile organic compounds (VOCs) emitted from different flower development stages of L.

A set of novel microsatellite markers developed for Luculia yunnanensis (Rubiaceae), an endangered plant endemic to Yunnan, China.

The genus Luculia Sweet contains about five species of small trees or shrubs and is a member of the family Rubiaceae (tribe Cinchoneae). Luculia yunnanensis is an endangered ornamental shrub endemic to southwest China. Only two natural populations of L.
