Development of drought-tolerant sugarcane overexpressing the AtDREB2A CA gene. Repositório Alice
SOUZA, W. R. de; OLIVEIRA, N. G. de; VINECKY, F.; RIBEIRO, A. P.; BASSO, M. F.; CASARI, R. A. das C. N.; DIAS, B. B. A.; NEPOMUCENO, A. L.; KOBAYASHI, A. K.; NAKASHIMA, K.; YAMAGUCHI-SHINOZAKI, K.; MOLINARI, H. B. C..
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...

Enhanced aluminum tolerance in sugarcane: evaluation of SbMATE overexpression and genome-wide identification of ALMTs in Saccharum spp. Repositório Alice
RIBEIRO, A. P.; VINECKY, F.; DUARTE, K. E.; SANTIAGO, T. R.; CASARI, R. A. das C. N.; HELL, A. F.; DIAS, B. B. A.; MARTINS, P. K.; CENTENO, D. da C.; OLIVEIRA, P. A. de; CANÇADO, G. M. de A.; MAGALHAES, J. V. de; KOBAYASHI, A. K.; SOUZA, W. R. de; MOLINARI, H. B. C..
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...

Kinetin and nitrogen in agronomic characteristics of soybean. Repositório Alice
FIDELIS, R. R.; SERAGLIO, N. A.; RAUBER, W. A.; MARQUES, K. R.; BORTOLON, L.; BORTOLON, E. S. O.; TAVARES, A. T.; ROTILI, E. A.; FREITAS, G. A. de; SOUZA, W. R. de; BARROS, H. B.; LEAL, T. H. V. L.; SOUSA, P. L. R.; BURIN, L. X..
The objective of this work was to evaluate the application of kinetin associated with nitrogen in coverage on the agronomic characteristics and soybean yield. In the 2016/2017 harvest, a 6x2 factorial scheme was used, six doses of kinetin (0; 0.30; 0.60; 0.90; 1.20; 1.50 g ha−1) and two doses of N (20 and 40 kg ha−1) and in the 2017/2018 harvest, factorial scheme 5x2 was used, five doses of kinetin (0; 0.25; 0.75; 1.00; 1.25 g ha−1) and two doses of N (20 and 40 kg ha−1). Agronomic plant height characteristics, first pod insertion height, number of grains per plant, number of pods per plant, number of grains per pod, number of grains per pod, hundred-grain mass and grain yield were evaluated. The use of N alone and...

Silencing of a BAHD acyltransferase in sugarcane increases biomass digestibility. Repositório Alice
SOUZA, W. R. de; PACHECO, T. F.; DUARTE, K. E.; SAMPAIO, B. L.; OLIVEIRA, P. A. de; MARTINS, P. M.; SANTIAGO, T. R.; FORMIGHIERI, E. F.; VINECKY, F.; RIBEIRO, A. P.; DIAS, B. B. A.; KOBAYASHI, A. K.; MITCHELL, R. A. C.; RODRIGUES, D. de S.; MOLINARI, H. B. C..
Background: Sugarcane (Saccharum spp.) covers vast areas of land (around 25 million ha worldwide), and its processing is already linked into infrastructure for producing bioethanol in many countries. This makes it an ideal candidate for improving composition of its residues (mostly cell walls), making them more suitable for cellulosic ethanol production. In this paper, we report an approach to improving saccharification of sugarcane straw by RNAi silencing of the recently discovered BAHD01 gene responsible for feruloylation of grass cell walls. Results: We identified six BAHD genes in the sugarcane genome (SacBAHDs) and generated five lines with substantially decreased SacBAHD01 expression. To find optimal conditions for determining saccharification of...
