Transcriptomic analysis reveals new role of circadian-regulated StBBX20 protein in potato reproduction

ABSTRACT: Analysis of gene expression in the apical shoot parts and stolons of StBBX20-silenced and -overexpressed potato lines was carried out via RNA-seq (two biological replicates). 5- and 7-week-old apical shoot parts (Figure S3) and 3-week-old stolons (Figure S4) samples were collected at ZT6 from four plants per pot (pooled technical replicates). Total cellular RNA was prepared using TRI Reagent® RT (Molecular Research Center, Inc.) and treated with DNase I during RNA purification. The quality and quantity of RNA were verified using a DS-11 FX spectrophotometer (DeNovix Inc.). RNA integrity number (RIN) of samples sufficient for sequencing (≥ 7) and rRNA ratio (≥ 1.7) was checked using Bioanalyzer RNA Nano 6000 chip (Agilent Technologies, Inc.). cDNA library construction using TruSeq Stranded mRNA LT Sample Prep Kit (Illumina) and sequencing using an Illumina platform with a 2 × 150 bp PE configuration were conducted by Macrogen Inc. (Seoul, Republic of Korea).

Transcriptional profiles associated with altered StCEN expression in non-swelling stolons from RNAi and overexpressing potato (subspecies Andigena) transgenic lines demonstrating altered tuberization phenotypes

Project description:Two independent Solanum tuberosum ssp. Andigena ADG StCEN RNAi and two ADG StCEN 35S overexpressing OE transgenic lines and a wild type WT control were grown under standard glasshouse conditions for 6 weeks prior to being moved to controlled growth cabinet conditions. Plants were grown under 4 different daylengths (8,10,12 and 16 hr) at 20 °C day and 14 °C night temperatures. ADG StCEN RNAi lines showed signs of early tuberization phenotype compared with the WT control after 23 days in the cabinets. Non-swelling stolons were harvested at this timepoint. ADG StCEN 35S OE lines demonstrated a delayed tuberization phenotype compared with the WT control. Non-swelling stolons were harvested after 38 days in the controlled cabinet conditions.

Comparative proteomics analyses of rhizomes and stolons in bermudagrass

Project description:As an important perennial warm-season turfgrass species, bermudagrass (Cynodon dactylon L.) form underground-growing rhizomes and aboveground-growing stolons simultaneously, making it a fast propagating clonal plant with strong regeneration ability. However, the intrinsic difference between the two types of specialized stems are still uncharacterized, especially at the molecular level. In the current study, we compared the internode proteomes of rhizomes and stolons at the same developmental stage in the bermudagrass cultivar Yangjiang using isobaric tags for relative and absolute quantitation (iTRAQ). The results indicated that 228 protein species were differentially accumulated in the two specialized stems. These DAPs comprise complex protein networks to finely regulate diverse cellular activities in the two types of specialized stems. Notably, photosynthesis and flavonoid biosynthesis were significantly regulated in stolons, whereas sucrose and starch metabolism were significantly regulated in rhizomes.

Bermudagrass stolon phosphoproteomics

Project description:As a widely used turfgrass species, bermudagrass (Cynodon dactylon L.) can be easily propagated by colonial growth of stolons. Previous studies collectively revealed that exotic environmental factors and intrinsic hormones and genes are all involved in the differentiation, development, and diageotropically growth of stolons. However, the detailed molecular mechanism how environmental and hormone signals regulate the gene expression and biochemical activities in bermudagrass stolons remains unclear. In this study, LC-MS/MS analyses of the total protein extracts of bermudagrass stolons without preliminary phosphopeptide-enrichment successfully identified 862 nonredundant phosphorylation sites and 613 phosphoproteins.

Identification of TIMING OF CAB EXPRESSION 1 as an environmentally sensitive negative regulator of tuberisation in potato

Project description:For many potato cultivars, tuber yield is optimal at average day time temperatures in the range of 14-22 ⁰C. Further rises in ambient temperature can reduce or completely inhibit potato tuber production, with damaging consequences for both producer and consumer. In our previous work we observed that the steady-state expression level of the core circadian clock gene, TIMING OF CAB EXPRESSION 1 (TOC1), in potato tubers increased at moderately elevated temperature, whereas expression of the tuberisation signal gene StSP6A decreased along with tuber yield. In this study we investigated the potential roles of StTOC1 in linking environmental signalling and potato tuberisation. We show that transgenic lines with decreased expression of StTOC1 exhibit enhanced StSP6A transcript levels in tuberising stolons, and show changes in gene expression consistent with elevated tuber sink strength.

Effects of StSP6A overexpression and silencing on potato stolons

Project description:Summary StSP6A is a protein with sequence homology to the Arabidopsis FLOWERING LOCUS T (FT). FT is a main component of the long range flowering promoting signal or florigen that induces photoperiodic flowering under long days (LDs). In potato, short days (SDs) promote tuber induction, and wild subspecies like Solanum tuberosum ssp andigena (wild type line 7540) are strictly dependent on SDs to tuberize. StSP6A transcription is induced in leaves and stolons at early stages upon transfer to SD inductive conditions, priotr to visible solon swelling. Transgenic andigena lines over-expressing the StSP6A gene under the control of the 35S promoter are able to tuberize under LD non-inductive conditions, whereas silencing of this gene by means of an specific RNAi construct are strongly delayed in tuber induction in SD inductive conditions. This data indicate that StSP6A plays a central role in the control of tuber induction. For each sample of the two comparisons (35S-StSP6A versus Wild Type and StSP6A-RNAi versus Wild Type) two biological replicates were prepared. In the case of 35S-StSP6A and StSP6A-RNAi each replicate was composed by a pool of several transgenic lines.

EST mining of yellow potato and gene expression profiling of its infection by P. infestans using SAGE - SOLEXA

Project description:The late blight pathogen, Phytophthora infestans has a broad host range within the Solanaceae family, including yellow potato (Solanum phureja). The disease caused by P. infestans in S. phureja is poorly understood and is a major concern in Colombia. Expressed Sequence Tag (EST) libraries obtained from a normalized library constructed from healthy plant tissue revealed high levels of sequence similarity between S. phureja and S. tuberosum. Then, utilizing Serial Analysis of Gene Expression and high-throughput sequencing (SAGE-Solexa), we characterized yellow potato gene expression during infection by P. infestans. Four-week-old yellow potato plants were inoculated with P. infestans and were collected at 12 and 72 hours post inoculation for RNA extraction. We detected differentially expressed genes by comparing inoculated to non-inoculated and resistant to susceptible plants. The discovery and characterization of the proteins mediating this host–pathogen interaction enable the understanding of the pathosystem and is the key for developing resistant plants. Keywords: SAGE-Solexa, inoculation response, transcript profiling, Solanum phureja, Phytophthora infestans Four-week-old yellow potato (Solanum phureja) plants were inoculated with Phytophthora infestans and were collected and flash frozen in liquid nitrogen at 12 and 72 hours post inoculation, as well as mock inoculated, for RNA extraction. 2 yellow potato cultivars (resistant and susceptible) were used for each experiment. Mock inoculated plants were collected in each replicate. RNA obtained from each of the three biological replicates was pooled to obtain a single RNA sample for each timepoint X cultivar combination. A total of 6 different SAGE libraries were thus obtained. For all libraries, Illumina sequencing was performed at Canada´s Michael Smith Genome Sciences Centre.
