| Sugarcane is considered an important economic crop not only for sugar production, but also for ethanol generation, serving as an expandable green alternative to the usage of crude oil. To take advantage of the use of sugarcane as a renewable source for bioethanol production, it is important to increase its productivity without increasing land usage, which includes sugarcane cultivation under hostile conditions, such as waterlimited environments. In this study, we demonstrated that stress-inducible overexpression of the transcription factor AtDREB2A CA conferred drought tolerance in sugarcane subjected to water deficiency under greenhouse conditions. In addition, transgenic plants expressing AtDREB2A CA accumulated higher levels of sucrose than... |

| Abstract. Background: A major limiting factor for plant growth is the aluminum (Al) toxicity in acidic soils, especially in tropical regions. The exclusion of Al from the root apex through root exudation of organic acids such as malate and citrate is one of the most ubiquitous tolerance mechanisms in the plant kingdom. Two families of anion channels that confer Al tolerance are well described in the literature, ALMT and MATE family. Results: In this study, sugarcane plants constitutively overexpressing the Sorghum bicolor MATE gene (SbMATE) showed improved tolerance to Al when compared to non-transgenic (NT) plants, characterized by sustained root growth and exclusion of aluminum from the root apex based on the result obtained with hematoxylin staining. In... |

| Tbe rep gene of Bean golden mosaic virus (BGMV) is essential for virus replication, and rep gene rnutations with amino acid codons cbanges in the putative NTP-binding rnotif D262R (MI) was created. Phaseolus vulgaris rransforrnation was achieved with a helium driven particle acceleration device. Tbe vector contained the bar gene [resistance to arnmonium glyphosinate (AG)] and besides the rep gene mutant. A total of J 7 initial - R(O) - transformants were analyzed. From the R(O) plant M1/4, which had mutation MI, six progeny plants with resistance to AG were obtained, and four remained BGMV symptomless after inoculation. From tbese four plants, a total progeny of 127 R(2) plants were inoculated. Of the 35 progenies of plant M 1/4/l, only three plants showed... |

| Water deficit is a major constraint for crops of economic importance in almost all agricultural regions. However, plants have an active defense system to adapt to these adverse conditions, acting in the reprogramming of gene expression responsible for encoding microRNAs (miRNAs). These miRNAs promote the regulation to the target gene expression by the post-transcriptional (PTGS) and transcriptional gene silencing (TGS), modulating several pathways including defense response to water deficit. The broader knowledge of the miRNA expression profile and its regulatory networks in response to water deficit can provide evidence for the development of new biotechnological tools for genetic improvement of several important crops. In this study, we used Setaria... |
