Project description:Drought-responsive genes in soybean leaves were successfully identified using Affymetrix Soybean Gene 1.0 ST arrays on leaves samples of reproductive-stage soybean plants. R1 soybean plants planted in pots were imposed drought by withholding water for 5 days until the soil moisture content dropped to 5%, and 3rd trifoliates (now at the R2 stage) were collected for expression profiling.

Project description:The response to moderate and heavy drought of two Solanum tuberosum ssp. Andigena varieties, Sullu (NP 03.03) and SA 2563 (NP 03.01), planted in rain- and soil water protected fields in the Peruvian highlands are compared. Previous experiments indicate that Sullu has a greater capacity for yield maintenance under drought than SA 2563. Both clones have similar morphological properties, vegetative periods and rooting depths, so it can be assumed that the cause for increased drought tolerance of clone NP 03.03 is rather due to physiological or biochemical mechanisms, than to drought escape by deep rooting or earliness. Sullu and SA 2563 were planted in a random block design with 5 plants per bloc and 7 repetitions per treatment. Treatments: (1) drought stress, (2) irrigated control The plants were drip-irrigated in both treatments until tuberization (until day 84 after planting). Subsequently, the irrigation was stopped in the drought field, but continued in the control field. The soil moisture content in the control field was kept near field capacity. Planting date: October 05 2004 Start of drought treatment (during tuberization, 84 days after planting): December 28 2004 First sampling (soil water potential: -0.3 mPa 114 days after planting): January 27 2005 Second sampling (soil water potential –0.6 MPa, 134 days after planting): February 15 2005 Harvest: March 19 2005 (165 days after planting) The experimental design includes gene expression analysis in leaves, roots and stolons at two time points, when soil water potential reaches -0.3 and –0.6 MPa. Gene expression changes will be set in relation with physiological and agronomical data obtained in the same experiment. Keywords: Direct comparison

Project description:Sago palm is an important agricultural starch producing plant which contributes to the economics of Malaysia where the trunk is the main plant part which the starch is stored. However, there are sago palms that planted on peat soil failed to develop its trunk even after 17 years been planted. This phenomenon is known as 'non-trunking', which eliminates the economic value of the plants. Numeral researches have been done to address the phenomenon but the molecular mechanisms of sago palm respond toward the responsible stresses are still lacking. Therefore, in this study we collected samples from Trunking (Normal) and Non-Trunking sago palm leaf samples which planted on peat soil for total RNA extraction followed by next generation sequencing using BGISEQ-500 platform. The raw reads were cleaned and de novo assembled using TRINITY software package. Total of 40.11 Gb bases were sequenced from the sago palm leaf samples and after assembled producing 102,447 unigenes, with N50 score 1,809 bp and GC ratio of 44.34%. Unigenes by aligning with 7 (NR, NT, GO, KOG, KEGG, SwissProt & InterPro) functional databases and 65,523 (63.96%) unigenes were annotated. Functional annotation results in the detection of 46,335 Coding DNA sequences by Transdecoder. 30,039 Simple-sequence repeats distributed on 21,676 Unigenes were detected using Primer3 software, and 2,355 Transcription Factor coding Unigenes were predicted using getorf and hmmseach software. A total of 492 up-regulated and 444 down-regulated at least two-fold differential expressed gene were detected using DESeq2 algorithm with 95% confidence.

Project description:Drought-responsive genes in soybean leaves were successfully obtained using soybean gene 1.0 ST array. Leaf samples from the vegetative stage of soybean plants were used. V6 soybean plants planted in the pots were imposed drought by withholding water for 6 days until the soil moisture content drop to 5% and trifolium 4th were collected for expression profiling

Project description:Drought-responsive genes in soybean leaves were successfully identified using Affymetrix Soybean Gene 1.0 ST arrays on leaves samples of reproductive-stage soybean plants. R1 soybean plants planted in pots were imposed drought by withholding water for 5 days until the soil moisture content dropped to 5%, and 3rd trifoliates (now at the R2 stage) were collected for expression profiling. Soybean plants were grown in pots. When the plants reached the R1 stage (started flowering), drought treatment was imposed by withholding water. The soil moisture content was monitored during the process until the 5th day of water withholding, when soil moisture content reached 5%. The 3rd trifoliate (counting from shoots), now at the R2 stage, was collected for total RNA extraction, while other 3rd trifoliates of similar chlorophyl index were collected for leaves water content determination to identify the severity of the stress. Total RNA from 3rd trifoliates were used for expression profiling using Affymetrix Soybean Gene 1.0 ST arrays. Four biological repeats per treatment were performed, three biological repeats were chosen for expression profiling.
