CitEST project resulted in the construction of cDNA libraries from different Citrus sp. tissues under various physiological conditions. Among them, plantlets of Rangpur lime were exposed to hydroponic conditions with and without water stress using PEG6000. RNA from roots was obtained and generated a total of 4,130 valid cDNA reads, with 2,020 from the non-stressed condition and 2,110 from the stressed set. Bioinformatic analyses measured the frequency of each read in the libraries and yielded an in silico transcriptional profile for each condition. A total of 40 contigs were differentially expressed and allowed to detect up-regulated homologue sequences to well known genes involved in stress response, such as aquaporins, dehydrin, sucrose synthase, and proline-related synthase. Some sequences could not be classified by using FunCat and remained with an unknown function. A large number of sequences presented high similarities to annotated genes involved with cell energy, protein synthesis and cellular transport, suggesting that Rangpur lime may sustain active cell growth under stressed condition. The presence of membrane transporters and cell signaling components could be an indication of a coordinated morphological adaptation and biochemical response during drought, helping to explain the higher tolerance of this rootstock to water stress. |

I. INTRODUCTION
The impact of soil organic carbon (SOC) dynamics on the global carbon cycle is still largely uncertain despite studies of agricultura! activities and contrai emissions of greenhouse gases to the Earth's atmosphere. The knowledge of soil organic matter (SOM) dynamics could indicate altematives to increment carbon sequestration. The Kyoto Protocol has created global warming response opportunities by means of a clean development mechanism that allows countries like Brazil to receive investments from companies and governments wishing to reduce their emissions of greenhouse gases. According to such protocol, reforestation and reclamation of degraded areas are alternatives to increase the SOM and also the soil carbon sequestration. Land management practices as no- tillage have been proposed as a possible means to sequestrate atmospheric carbon, helping to refurbish sair fertility and replenish the organic matter lost as a result of previous agricultura! management practices. There are around 17 millions of hectares under no-tillage system in Brazil, representing about 30% of grain cultivated area. The use of no-tillage system has increased mainly over the last decade, and a significant contribution towards the reduction of soil CO2 emissions has been anticipated (Lal, 2001; Bayer et al., 2002). The present study aims to quantify the carbon storage in soils under different tillage systems used to sugar-Gane cultivation as well as to realize the characterization of humic acids extracted from these cultivated areas by electron spin resonance (ESR) and laser induced fluorescence (LIF) spectroscopies.
