Última Changes in anatomy and root cell ultrastructure of soybean genotypes under manganese stress Rev. Bras. Ciênc. Solo Lavres Junior,José; Malavolta,Eurípedes; Nogueira,Neusa de Lima; Moraes,Milton Ferreira; Reis,André Rodrigues; Rossi,Mônica Lanzoni; Cabral,Cleusa Pereira. The deleterious effects of both Mn deficiency and excess on the development of plants have been evaluated with regard to aspects of shoot anatomy, ultrastructure and biochemistry, focusing mainly on the manifestation of visual symptoms. However, there is little information in the literature on changes in the root system in response to Mn supply. The objective of this study was to evaluate the effects of Mn doses (0.5, 2.0 and 200.0 μmol L-1) in a nutrient solution on the anatomy of leaves and roots of the Glycine max (L.) cultivars Santa Rosa, IAC-15 and IAC-Foscarin 31. Visual deficiency symptoms were first observed in Santa Rosa and IAC-15, which were also the only cultivars where Mn-toxicity symptoms were observed. Only in IAC-15, a high Mn supply led...

HUBER,DONALD J.; KARAKURT,YASAR; JEONG,JIWON. Pectin depolymerization during fruit ripening has been shown to be largely due to pectinolytic enzymes, including polygalacturonases (E.C. 3.2.1.15) and pectinmethylesterases (E.C. 3.2.1.11). Studies have shown that these enzymes are not the primary determinants of softening, although participation in texture changes during the late stages of ripening seems evident. Pectin depolymerization differs significantly between various fruit types, notably avocado and tomato, even though levels of extractable PG activity in these fruits are similar. Collective evidence indicates that the activities of some cell wall enzymes are restricted in vivo, with maximum hydrolytic potential expressed only in response to tissue disruption or wounding. In contrast, other... Tipo: Info:eu-repo/semantics/article Palavras-chave: Apoplast; Lipids; Membranes; Oligogalacturonides; Pectin fragments; Polygalacturonase; Radical oxygen species.
