(Submitter supplied) Purpose: To study the effects of drought at the transcriptomic level on two different actively dividing maize tissue: the ovaries, and the leaf meristem Methods: The Illumina reads were mapped to the maize B73 reference genome using Tophat followed by transcriptome reconstruction using Cufflinks. The FPKM valuse were extracted from cufflinks output and an R package called Limma was used to identify differentially expressed genes under drought under both tissues Results and Conclusions: Different processes which were differentially expressed under drought in both tissues were identified and analyzed in detail. more...

(Submitter supplied) Background: Grapevine is a major food crop that is affected by global climate change. Consistent with field studies, dehydration assays of grapevine leaves can reveal valuable information of the plant’s response at physiological, transcript, and protein levels. There are well-known differences in grapevine rootstocks responses to dehydration. We used time-series transcriptomic approaches combined with network analyses to elucidate and identify important physiological processes and network hubs that respond to dehydration in three different grapevine species differing in their drought tolerance. more...

(Submitter supplied) The mitogen-activated protein kinase (MAPK) cascade is an evolutionarily conserved signal transduction pathway that is involved in plant development and stress responses. As the first component of this phosphorelay cascade, mitogen-activated protein kinase kinase kinases (MAPKKKs) act as adaptors linking upstream signaling steps to the core MAPK cascade to promote the appropriate cellular responses; however, the functions of MAPKKKs in maize are unclear. more...

(Submitter supplied) Results: In this study, the ears at the V9 stage, kernels and ear leaf at the 5DAP (days after pollination) stage of maize were used for morphological, physiological and comparative transcriptomics analysis to understand the different features of “sink” or “source” organs and the effects on kernel yield under drought stress conditions. The ABA-, NAC-mediate signaling pathway, osmotic protective substance synthesis and protein folding response were identified as common drought stress response in the three organs. more...

(Submitter supplied) Drought is a major abiotic stress that threatens global food security. Circular RNAs (circRNAs) are endogenous RNAs. How these molecules influence plant stress responses remains elusive. Here, a large scale circRNA profiling identified 2174 and 1354 high-confidence circRNAs in maize and Arabidopsis, respectively, and most were differentially expressed in response to drought. A substantial number of drought-associated circRNA hosting genes were involved in conserved or species-specific pathways in drought responses. more...

(Submitter supplied) BiP overexpression confers resistance to drought, through an as yet unknown mechanism that is related to ER functioning, has been described that the delay in leaf senescence by BiP overexpression might relate to the absence of the response to drought. We used microarrays to detail the global programme of gene expression underlying in soybean leaves overexpressing BiP and with different water potentials to elucidate the mechanisms by which BiP protects plant cells against cell death induced by dehydration.

(Submitter supplied) During their lifespan, plants continuously respond to a multitude of stressful factors that affects their development and reproductive fitness through a sophisticated variety of physiological, biochemical, transcriptional, and epigenetic mechanisms. Dynamic changes in chromatin structure and concomitant transcriptional variations play an important role in both stress response and adaptation. Epigenetic memory mechanisms seem to be involved because chromatin and expression patterns can be indeed stably maintained during cell division, once the triggering stimulus has been removed. more...

(Submitter supplied) Drought stress is one of the main environmental factors that affects growth and productivity of crop plants, including lentil. To gain insights into the genome-wide transcriptional regulation in lentil root and leaf under short- and long-term drought conditions, we performed RNA-seq on a drought-sensitive lentil cultivar (Lens culinaris Medik. cv. Sultan). After establishing drought conditions, lentil samples were subjected to de novo RNA-seq-based transcriptome analysis. more...

(Submitter supplied) 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.
