Pea Plant Pisum sativum
The fine structure of pea stomata
by Singh A. P., Srivastava L. M. (1973)
in Protoplasma 76: 61-82. –
The structure and cytology of the guard cells of pea are described. The differential wall thickenings, the radiate arrangement of wall fibrils from the pore site to the anticlinal walls, the lobed and dissected nature of the vacuole, and the fine structure of the plastids are believed to play a significant role in stomatal opening and closing.
These findings are correlated with those on corn stomata. Finally a few points with regard to the role of microtubules and vesicles in wall thickenings are discussed.
