Project description:Pollen germination, along with pollen tube growth, is an essential process for the reproduction of flowering plants. The germinating pollen with tip-growth characteristics provides an ideal model system for the study of cell growth and morphogenesis. As an essential step towards a detailed understanding of this important process, the objective of this study was to comprehensively analyze the transcriptome changes during pollen germination and pollen tube growth. Using Affymetrix Arabidopsis ATH1 Genome Arrays, this study is the first to show the changes in the transcriptome from desiccated mature pollen grains to hydrated pollen grains and then to pollen tubes of Arabidopsis thaliana. The number of expressed genes, either for total expressed genes or for specifically expressed genes, increased significantly from desiccated mature pollen to hydrated pollen and again to growing pollen tubes, which is consistent with the finding that pollen germination and tube growth was significantly inhibited in vitro by a transcriptional inhibitor. The results of GO analyses showed that expression of genes related to cell rescue, transcription, signal transduction and cellular transport were significantly changed, especially for up-regulation, during pollen germination and tube growth, respectively. In particular, genes of the CaM/CML, CHX and Hsp families showed the most significant changes during pollen germination and tube growth. These results demonstrate that the overall transcription of genes, both in the number of expressed genes and in the levels of transcription, was increased. Furthermore, the appearance of many novel transcripts during pollen germination as well as tube growth indicates that these newly expressed genes may function in this complex process.

Transcriptome analyses show changes in gene expression to accompany pollen germination and tube growth in Arabidopsis. Plant Physiol. September 5, 2008; 10.1104/pp.108.126375 Experiment Overall Design: Three samples are analyzed in this experiment. They are desiccated mature pollen grains (MP), hydrated pollen grains (HP) and growing pollen tubes (PT) of Arabidopsis thaliana, respectively. Each sample has two biological replicates, so that there are 6 data sets of ATH1 array in this experiment.

Project description:- Pollen tube growth is important process for successful double fertilization, which is critical for grain yield in crop plants. Despite much progress in identification of rapid alkalization factors (RALFs) which serve as ligand for signaling transduction during fertilization in Arabidopsis, there is no functional study of RALF in mono-cotyledon plant. - We functionally characterized two pollen specific RALF in rice (Oryza sativa) using multiple CRISPR/Cas9 induced loss-of-function mutants, peptide treatment, expression analyses, tag reporter lines. - OsRALF17 is specifically expressed in pollen and pollen tube as the strongest level among 41 RALF members in rice. Exogenously applied OsRALF17 inhibits pollen tube germination and elongation at high concentration, but enhances tube elongation at low concentration, indicating the regulation of growth balance. Double mutant of OsRALF17 with OsRALF19 exhibit almost male sterile, with defect on pollen germination and tube elongation. - Our study revealed that functionally-redundant OsRALF17 and 19 peptides binds to the OsMTD2, CrRLK1L family member, and transmits ROS signal for pollen tube germination and integrity maintenance in rice. We provide new insights into the role of RALF and expanding our understanding of the biological role of RALF in regulating rice fertilization.

Project description:Arabinogalactan proteins are proteoglycans known to have important roles during cell growth and development, namelly during pollen tube growth. A microarray experiment was performed on agp6 agp11 pollen tubes to search for genetic interactions in the context of pollen tube growth. RNA from wt and mutant pollen tubes was extracted after 8h of in vitro germination and hybridized on Affimetrix microarrays.
