Photoperiod-dependent flowering is a critical trait in breeding for flowering time in woody ornamental plants. Circadian clocks are vital for the regulation of photoperiodic flowering in plants, but their molecular regulation pathways in woody perennials remain poorly explored. Here, we identified two circadian clock components LgPSEUDO-RESPONSE RE...

Photoperiod-regulated floral transition is vital to the flowering plant. Luculia gratissima “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 L. gratissima is unclear. To systematically research the res...

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 va...

Phyllanthus emblica 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. The plant is widely distributed in Southwestern and Southern China. However, due to massive deforestation and land reclamation as well as deterioration of its natural hab...

Background: Photoperiod-regulated floral transition is vital to the flowering plant. Luculia gratissima ‘Xiangfei’ is a flowering ornamental plant with high development potential and is a short-day woody perennial. However, the genetic regulation of short-day-induced floral transition in L. gratissima is unclear. To systematically research the resp...

Objective To study the changes of key endogenous substances during flowering process in Luculia gratissima 'Xiangfei' and try to provide references for artificial regulating of flowering time. Method The buds from various stages, including vegetative growth phase, undifferentiation phase, bract primordium differentiation phase, inflorescence primor...

In order to comprehensively understand the characteristics of distribution and variation of the SSR loci in the transcriptome of Phyllanthus emblica L., transcriptome sequencing was conducted on young leaves of P.emblica by using Illumina Hiseq 4000. The SSR loci were studied using MISA software from the obtained unigenes. A total of 9 991 SSRs dis...

ObjectiveTo provide comprehensive genetic information for the development of microsatellite markers and the mining of functional genes in Phyllanthus emblica by characterizing the transcriptome of P. emblica in dry-hot valleys in Yunnan. MethodTranscriptome sequencing was conducted on young leaves of Ph. emblica using Illumina Hiseq 4000, followed...

Premise of the Study A novel set of EST‐SSR markers was developed for Phyllanthus emblica (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 P. emblica, 83 EST‐SSR primer pairs were designed; 52 prim...

Premise of the Study To investigate the genetic background and population characteristics of Rhododendron longipedicellatum (Ericaceae), a newly discovered and critically endangered species, expressed sequence tag–simple sequence repeat markers were developed, and transferability was tested in two congeners, R. molle and R. simsii. Methods and Res...

ObjectiveTo provide some references for the studies on genetic breeding, pollen germplasm preservation and pollination biology of Rhododendron longipedicellatum by investigating the pollen grains morphology and its characteristics. Method The pollen grains of R. longipedicellatum at different development stages including alabastrum intumescence sta...

Phyllanthus emblica is a famous medicinal and edible plant, whose fruit contains various therapeutic components and has extremely high medicinal value and development potential. However, the weaknesses such as sour taste have seriously restricted the development of its related industries, and it is urgent to carry out genetic improvement on the rel...

Rhododendron longipedicellatum is a narrow endemic species and a subject of urgent demand in the domestic market and overseas.
