Desenvolvimento de laticíferos: ultraestrutura, citoquímica e expressão gênica

“…Enzymatic digestion of middle lamella is an important process that have been related to both anastomosis and intrusive growth (Marinho and Teixeira, 2019) and ultrastructural analyses have labeled cellulases and pectinases in the cell walls and vacuoles of laticifers, as well as in adjacent cells (Allen and Nessler, 1984;Marinho and Teixeira, 2019). Latex serves as a strong defense for plants, and the high amount of diverse enzymes is common in latex (Konno et al, 2004;Agrawal and Konno, 2009;Wasano et al, 2009;Konno, 2011;de Freitas et al, 2016;Ramos et al, 2019Ramos et al, , 2020Cruz et al, 2020). However, it is not clear if the digestive enzymes detected in anastomosing laticifers are the product of the digestion of their terminal walls or a latex component with defensive function.…”
