14. Aluminum-induced genes in grass species.
This study aimed to identify genes associated with Al tolerance mechanisms in grasses, using cDNA and subtracitve libraries derived from roots of maize, rice, sorghum, oat, barley, wheat and brachiaria tolerant genotypes submitted to critical levels of Al in nutrient solution.

15. Phosphate solubilization and synergism between P-solubilizing and arbuscular mycorrhizal fungi.
The objective of this work was to evaluate the ability of several P-solubilizing fungi to solubilize aluminum phosphate and Araxá apatite as well as the synergism between the P-solubilizing fungus, PSF 7, and arbuscular mycorrhizal fungi to promote clover growth amended with aluminum phosphate. Two experiments were carried out, the first under laboratory co

16. Transcriptional profile of maize roots under acid soil growth.
Aluminum (Al) toxicity is one of the most important yield-limiting factors of many crops worldwide. The primary symptom of Al toxicity syndrome is the inhibition of root growth leading to poor water and nutrient absorption. Al tolerance has been extensively studied using hydroponic experiments. However, unlike soil conditions, this method does not address al

17. Aluminum-induced genes in grass species.
The toxicity caused by aluminum (Al), intrinsic to acid soils, in?uences negatively the stability of crop production. Under toxic levels of Al, plant roots paralyze their development and become unable to explore the deeper layers of the soil, affecting nutrient and water acquisition and reducing crop yield. This study aimed to identify genes associated with

18. Melhoramento genético de Lotus corniculatus visando tolerância à toxidez por alumínio / Lotus corniculatus breeding for tolerance to aluminum toxicity
Solos ácidos com toxidez por Al são comuns, sendo geralmente destinados à pecuária. A utilização de leguminosas forrageiras adaptadas a esta situação minimizaria o uso de correção de acidez e ainda possibilitaria um aporte de N ao sistema via fixação biológica. A caracterização e a identificação de mecanismos de tolerância ao Al tóxico sã

19. Respostas à deficiência de fósforo e suas relações com a tolerância ao alumínio em trigo / Phosphorus deficiency responses and its relationship to aluminum tolerance in wheat
A inibição do crescimento das culturas causada na condição de solos ácidos, devido principalmente pela deficiência de fósforo (P) e toxidez de alumínio (Al), é um sério problema para a produção agrícola. Em trigo, a cv. Toropi foi identificada como altamente tolerante ao Al e, também apresenta tolerância à presença de baixo P, quando compara

20. Genótipos de aveia branca (Avena sativa L.) submetidos a diferentes protocolos e doses de alumínio em cultivo hidropônico. / White oat genotypes (Avena sativa L.) subjected to different methodologies and aluminum levels under hydroponic conditions.
The ability to perform experiments under controlled conditions employment of evaluations in controlled environment such as hydroponic culture has attracted crop breeders attention regarding the selection of aluminum (Al) tolerant plants. This strategy facilitates the detection of plant injuries in early stages of development, representing a non-destructive m

21. ValidaÃÃo do efeito do gene AltSB que controla a tolerÃncia ao alumÃnio em sorgo / Validation of the effect of the gene AltSB that controls the tolerance to aluminum toxicity in Sorghum
A toxicidade ao alumÃnio à um dos principais fatores limitantes à expansÃo da produÃÃo em solos Ãcidos, os quais representam uma grande Ãrea com capacidade produtiva de regiÃes tropicais e subtropicais. O presente trabalho foi realizado com os objetivos de realizar a validaÃÃo, no campo, de linhagens de sorgo classificados como tolerantes e suscep

22. BIOCHEMICAL AND PHYSIOLOGICAL EVALUATION OF POTATO CLONES IN RELATION TO ALUMINUM / AVALIAÇÃO BIOQUÍMICA-FISIOLÓGICA DE CLONES DE BATATA EM RELAÇÃO AO ALUMÍNIO
Aluminum (Al) is the most abundant metal in the earths crust, affecting thegrowth and development of plants. The objective of this work was to investigate and compare biochemical and physiological responses of potato clones, Macaca, SMIC148-A, Dakota Rose and Solanum microdontum, exposed to 0, 50, 100, 150 and 200 mg Al L-1 in nutrient solution (pH 4.0).

23. Superexpression of the ADP/ATP Translocase in Maize Under Saline and Aluminum Stresses / SuperexpressÃo do ADP/ATP translocase em milho submetido aos estresses salino e de alumÃnio
The Brazilian Cerrado occupies an area with about 207 million hectares distributed in 12 states In this region the soils are acid with little organic substance and high aluminum levels Under the form of free ions the aluminum becomes toxic for the plants and affects their growth and development Maize considered an important culture in these areas suffers sev

24. Defense systems against oxidative stresses in two rice cultivars (Oryza sativa L.) with differential tolerance to aluminum / Sistemas de defesa contra estresses oxidativos em dois cultivares de arroz (Oryza sativa L.) com tolerância diferencial ao alumínio
Aluminum (Al) effects on the growth and enzymatic and non-enzymatic antioxidative mechanisms involved in the scavenging of reactive oxygen species (ROIs) in two rice cultivars: Fernandes (CNA-1158) and Maravilha (CNA-6843-1) with differential tolerance to Al were studied. The plants, grown in pH 4.0 nutrient solution, for ten days in nutrient solution, pH 4,
