Project description:Lotus (Nelumbo nucifera Gaertn) belongs to the family Nymphaeaceae, and is a popular aquatic vegetable that is rich in nutrients. It is widely cultivated in China, and many varieties of lotus are used for different purposes, suited to different climates, and consumed in different ways. Lotus is commonly produced by asexual propagation, so mutation through hybridization and variation fixed by asexual propagation are the main ways to create new varieties. Therefore, the formation of adventitious roots (ARs) in lotus, which does not have a well-developed principal root, is an important part of growth and development. It would be very useful to control ARs formation for lotus production and breeding.

Project description:Nelumbo, a perennial aquatic herbage that belongs to the family of Nelumbonaceae, comprises two extant species: N. nucifera Gaertn. and N. lutea (Wild.) Pers. Based on a previous study, N. nucifera is distributed in over Asia and Northern Australia while N. lutea is found in North America and northern of South America (1). N. nucifera can be divided into two cultivars including temperate lotus and tropical lotus based on its rhizome phenotype. The temperate lotus rhizome is expanded at the end of growth while tropical lotus root is of no significant enlargement during development (2). Normally, the temperate lotus root buds germinate in April, thereafter it takes several days from sowing to long roots and leaves. In mid-to-late may, vertical leaves rise out of the water, following July and August are the blooming period. Secondarily the first half of September is the final flowering period. The fruit ripening period is from late July to mid September, which is also the period of stem expansion and enrichment. After mid-October, it’s the dormant period, which is the lotus storage organ’s substance accumulation period. Thus the storage organ, mainly lotus rhizome, provides the energy for the lifecycle (Fig.1). Lotus rhizome, which is called metamorphic storage organ, is a kind of modified subterraneous stem, like potato (Solanum tuberosum) tuber and onion (Allium cepa L.) bulb (3). Most parts of lotus like rhizome, leaf, lotus seed and germ are used for traditional medicine (4). Rhizome especially is a kind of popular vegetable in Asia for its richness in nutrients including starch, proteins, vitamins (5). Nowadays it is a worldwide product in the form of the processed and semi-finished form like tea and vegetables. In general, the development of lotus rhizome can be classified into four stages: stolon stage, initial swelling, middle swelling, and later swelling stage (6, 7). The first three stages mainly focus on cell division and synthesis of some important carbohydrates, like starch, which play a critical part in the quantity and quality of rhizome, while accumulation of starch greatly increases at the last stage. Numerous studies have done in lotus to shed light on the environmental factors and morphometric indexes relevant to rhizome formation (8, 9). Short day light and low temperature promote tuber formation (10, 11). Also genes and proteins related to hormone, photoperiod (12, 13), starch synthesis (14, 15) and flowering time locus family genes were involved in the lotus rhizome formation (16). Previous studies include transcriptomics (6), genomics (17) and certain physiological researches, revealing numerous genes involved in photoperiod pathway, starch metabolism and hormone signal transduction, trying to make lotus a model plant of rhizome growth, while there is a lack of protein-level dynamic analysis and protein phosphorylation information, which is a strong proof for the dynamic processes in lotus rhizome. Proteomics is an indispensable method in storage organs research findings (18, 19), 2-DE and MALDI-TOF-TOF was employed to find some different protein profiles in fresh-cut lotus tuber before and after browning (20). And comparative proteomic was employed to analyze the Horsetail (Equisetum hyemale) underground stem to throw light upon the related proteins of developing rhizomes in ancient vascular plant Equisetum hyemale and different monocot species (21). Proteomics can also assist us in getting the changes of proteins in differently treated samples of potato tuber by using a LC-MS spectral-counting proteomics strategy (1), and shed light on the molecular basis of tuberization in potato to monitor differentially expressed proteins at different development stages (22). But the proteomic study of lotus rhizome enlargement hasn’t been reported now. Here, we employed comparative proteomics and phosphoproteomics to get proteins and its phosphorylation changes in the course of different rhizome development stages. Our data highlights some pathways, proteins and phosphorylated proteins during the development, and the difference between proteome and phosphoproteome in rhizome formation process.

Project description:Arbuscular mycorrhiza (AM) interactions between plants and Glomeromycota fungi primarily support phosphate aquisition of most terrestrial plant species. To unravel gene expression during early stages of Medicago truncatula root colonization by AM fungi, we used genome-wide transcriptome profiling based on mycorrhizal root fragments enriched for early fungal infection stages. We used Medicago GeneChips to detail the global programme of gene expression in response to early stages of colonization by arbuscular mycorrhizal fungi and identified genes differentially expressed during these early stages.

Project description:Key genes involved in symbiosis have been lost in nonmycorrhizal plants such as Arabidopsis thaliana. We studied the effects on gene expression in A. thaliana expressing an abbreviated, functional version of one of genes, the transcription factor Interacting Protein of DMI3 (IPD3-min), under low nutrient conditions in the presence and absence of a mycorrhizal fungi, Rhizophagus. We conducted the same transcriptome analysis with a cyclops-4 knockout mutant in Lotus japonicus to compare with the expression profile of a mycorrhizal host model lacking IPD3.

Project description:Arbuscular mycorrhiza (AM) interactions between plants and Glomeromycota fungi primarily support phosphate aquisition of most terrestrial plant species. To unravel cell-type specific gene expression during early stages of Medicago truncatula root colonization by AM fungi, we used genome-wide transcriptome profiling based on laser-microdissected cells. We used Medicago GeneChips to detail the cell-type specific programme of gene expression in early stages of colonization by arbuscular mycorrhizal fungi and identified genes differentially expressed during these stages. Medicago truncatula Gaertn M-bM-^@M-^XJemalongM-bM-^@M-^Y genotype A17 plantlets were grown in the climate chamber. Plants grown for the collection appressorial root areas (APP) and the corresponding non-appressorial root areas (NAP) were mycorrhized after 3 weeks and roots were harvested at 5-6 dpi.

We used Medicago GeneChips to detail the global programme of gene expression in response to early stages of colonization by arbuscular mycorrhizal fungi and identified genes differentially expressed during these early stages. Medicago truncatula GFP-HDEL hairy roots (genotypes A17 and DMI3) were grown in vertically-oriented petri dishes, incubated at 26M-BM-0C and inoculated with 8 Gigaspora margarita spores, which were positioned between the lateral roots. G.margarita spores germinated in 2 to 4 days. Hyphopodia were observed after 5-6 days. Root fragments which reacted to the fungal contact were collected and frozen. Non-inoculated control root fragments were harvested at a comparable age.
