Rhododendron molle G. Don occupies an important phylogenetic node in the genus rhododendron with unique yellow flower and medicinal functions. However, only limited genetic resources and their genome information are available for the generation of rhododendron flowers. The next generation sequencing technologies enables generation of genomic resources in a short time and at a minimal cost, and therefore provide a turning point for rhododendron research. Our goal is to use the genetic information to facilitate the relevant research on flowering and flower color formation in R...

BACKGROUND: Hazel (Corylus spp.) exhibits ovary differentiation and development that is initiated from the ovary primordium after pollination, conferring the plant with a unique delayed fertilization. Failure of development of the ovary and ovule after pollination can lead to ovary abortion and blank fruit formation, respectively, with consequent yield loss. However, the genes involved in ovary and ovule differentiation and development are largely unknown. RESULTS: In unpollinated pistillate inflorescences (stage F), the stigma shows an extension growth pattern...

Yun Xie, Xuewen Wang
Fruit yield is an important trait for horticultural crops. However, the limited fruit yield of Camellia chekiangoleosa, a novel promising oil tree, restricts the production of oil. The breeding improvement is little due to its long generation time and lack of available genomic sequence. We identified distinct fruit count phenotypes, high-yield (HY) and low-yield (LY). To understand the underlying genetic basis, we focused on global gene discovery and expression levels in floral buds, which affect fruit count...

Stem-borers in the genus Papaipema (Lepidoptera: Noctuidae) range from highly polyphagous agricultural pests to specialists on more than 20 families of flowering plants, many of them highly toxic. Papaipema is the largest genus of noctuids endemic to North America and provides an excellent study system for the evolution of noctuid host plant use. To improve the availability of genomic resources for such investigations, we performed de novo transcriptome sequencing and assembly for two specialist Papaipema with unusual larval hosts: P...

Plukenetia volubilis is a promising oilseed crop due to its seeds being rich in unsaturated fatty acids, especially alpha-linolenic acid. P. volubilis is monoecious, with separate male and female flowers on the same inflorescence. We previously reported that male flowers were converted to female flowers by exogenous cytokinin (6-benzyladenine, 6-BA) treatment in P. volubilis. To identify candidate genes associated with floral sex differentiation of P. volubilis, we performed de novo transcriptome assembly and comparative analysis on control male inflorescence buds (MIB) and female inflorescence buds (FIB) induced by 6-BA using Illumina sequencing technology...

Pea ( Pisum sativum L.) is a model plant that has been used in classical genetics and organ development studies. However, its large and complex genome has hindered research investigations in pea. Here, we generated transcriptomes from different tissues or organs of three pea accessions using next-generation sequencing to assess single nucleotide polymorphisms (SNPs), and further investigated petal differentially expressed genes to elucidate the mechanisms regulating floral zygomorphy. Eighteen samples were sequenced, which yielded a total of 617 million clean reads, and de novo assembly resulted in 87,137 unigenes...

BACKGROUND: Coccinia grandis (ivy gourd), is a dioecious member of Cucurbitaceae having heteromorphic sex chromosomes. Chromosome constitution of male and female plants of C. grandis is 22A + XY and 22A + XX respectively. Earlier we showed that a unique gynomonoecious form of C. grandis (22A + XX) also exists in nature bearing morphologically hermaphrodite flowers (GyM-H). Additionally, application of silver nitrate (AgNO3 ) on female plants induces stamen development leading to the formation of morphologically hermaphrodite flowers (Ag-H) despite the absence of Y-chromosome...

Aconitum carmichaelii is an important medicinal herb used widely in China, Japan, India, Korea, and other Asian countries. While extensive research on the characterization of metabolic extracts of A. carmichaelii has shown accumulation of numerous bioactive metabolites including aconitine and aconitine-type diterpene alkaloids, its biosynthetic pathway remains largely unknown. Biosynthesis of these secondary metabolites is tightly controlled and mostly occurs in a tissue-specific manner; therefore, transcriptome analysis across multiple tissues is an attractive method to identify the molecular components involved for further functional characterization...

BACKGROUND: Downy mildew, caused by the oomycete pathogen Sclerospora graminicola, is an economically important disease of Gramineae crops including foxtail millet (Setaria italica). Plants infected with S. graminicola are generally stunted and often undergo a transformation of flower organs into leaves (phyllody or witches' broom), resulting in serious yield loss. To establish the molecular basis of downy mildew disease in foxtail millet, we carried out whole-genome sequencing and an RNA-seq analysis of S...

BACKGROUND: Pennycress [Thlaspi arvense L (Brassicaceae)] is being domesticated as a renewable biodiesel feedstock that also provides crucial ecosystems services, including as a nutritional resource for pollinators. However, its flowers produce significantly less nectar than other crop relatives in the Brassicaceae. This study was undertaken to understand the basic biology of the pennycress nectary as an initial step toward the possibility of enhancing nectar output from its flowers. RESULTS: Pennycress flowers contain four equivalent nectaries located extrastaminally at the base of the insertion sites of short and long stamens...

Crested wheatgrass ( Agropyron cristatum L.) breeding programs aim to develop later maturing cultivars for extending early spring grazing in Western Canada. Plant maturity is a complex genetic trait, and little is known about genes associated with late maturity in this species. An attempt was made using RNA-Seq to profile the transcriptome of crested wheatgrass maturity and to analyze differentially expressed genes (DEGs) between early and late maturing lines. Three cDNA libraries for each line were generated by sampling leaves at the stem elongation stage, spikes at the boot and anthesis stages...

Camellia sasanqua is one of the most famous horticultural plants in Camellia (Theaceae) due to its aesthetic appeal as landscape plant. Knowledge regarding the genetic basis of flowering time, floral aroma and color in C. sasanqua is limited, but is essential to breed new varieties with desired floral traits. Here, we described the de novo transcriptome of young leaves, flower buds and flowers of C. sasanqua. A total of 60,127 unigenes were functionally annotated based on the sequence similarity. After analysis, we found that two floral integrator genes, SOC1 and AP1, in flowering time pathway showed evidence of gene family expansion...
