Mexican maize landraces under drought stress and recovery irrigation

Project description:Transcriptional profiling of three mexican maize landraces under 10, and 17 days stress and recovery irrigation A dye balanced modified loop design was implemented. Two biological replicates (pooling five representative plants) representing each sampling point for each genotype were obtained for purified RNA from 120 randomly chosen seedlings. This experiment involved a total of forty-eight (24 sets) of microarray hybridizations, including direct and dye swap comparisons between treatments as well as across the three landraces. This design allowed us to determine differences in gene expression between the three different landraces under drought stress (10 and 17 days) and at recovery irrigation compared to irrigated controls.

Molecular mechanism of negative pressure irrigation inhibiting root growth and improving water use efficiency in maize

Project description:NPI enriched more down-regulation genes involved in starch and sucrose metabolism, phenylpropanoid biosynthesis, amino sugar and nucleotide sugar metabolism, glycolysis/gluconeogenesis pathway, leading to restricted root growth. Three GO terms including channel activity, water transport, and water channel activity caused a high degree of gene enrichment. Thirteen genes related to water absorption and transport such as ZM00001D003006, ZM00001D014285 et al. were highly up-regulated, which might be the key genes for the significant increase in water use efficiency of maize under negative pressure irrigation.

W23 and High altitude maize under solar and supplementary UV-B

Project description:Additional to GSE1807 A comparative analysis, by expression profiling of maize, was performed to identify novel components in the mechanisms of maize responses to UV-B. Five high-altitude landraces grown from 2,000 to 3,400 m naturally receive higher UV-B fluence than plants at lower altitudes and similar latitudes. These high-altitude landraces were compared directly with a low-altitude line and with literature reports for other temperate maize lines. A microarray analysis demonstrated that among the UV-B responsive transcripts, several types of gene implicated in chromatin remodeling are differentially expressed before and after UV-B treatment in high-altitude lines. RNAi transgenic plants with lower expression of four such chromatin-associated genes exhibited hypersensitivity to UV-B by measurements of leaf arching, increased leaf chlorosis and necrosis, and altered UV-B regulation of selected genes. These results collectively suggest that genes involved in chromatin remodeling are crucial for UV-B acclimation and that some high-altitude lines exhibit adaptations to this challenge.

Metabonomics analysis reveals the physiological mechanism of promoting maize shoots growth under negative pressure to stabilize soil water content

Project description:The purpose of this study is to analyze maize shoots growth under negative pressure to stabilize soil water content，Maize plants were subjected to two irrigation treatments. The first treatment was soil moisture dry-wet cycles, which was obtained using drip irrigation (control, DW). The second treatment was negative pressure to stabilize soil water content treatment (SW), which was obtained using the negative pressure irrigation (NPI) system.

Identification of stress response and recovery mechanisms by multi-scale analyses of drought effect in the maize leaf growth zone.

Project description:We use the gowth zone of the maize leaf as a model system to study the growth reduction in response to drought stress. The spatial gradient and the relatively large size of the maize leaf allowed us to sample at a subzonal rezolution and to examine different developmental stages at the same time. We compared the response to different levels of drought stress (mild and severe) of proliferating (meristem), expanding (elongation zone) and differentiated (mature zone) tissue.
