Sample text

Adenylyl cyclase is a membrane-bound enzyme that catalyzes the production of cAMP from adenosine triphosphate (ATP). The adenylate cyclase gene MAC1 was cloned from M. grisea (Choi and Dean, 1997). Transformants lacking MAC1 gene were unable to form appressoria on an inductive surface and were unable to penetrate susceptible rice leaves. Appressorium formation was restored in the presence of exogenous cAMP derivatives (Choi and Dean, 1997). It suggests that MAC1 gene may function upstream of cAMP.

Exogenous cAMP and diacylglycerol suppressed defects associated with pth11 mutants. cAMP restored both appressorium formation and pathogenicity, whereas diacylglycerol only restored appressorium formation. , 1999). , 2003). , 1997). 2 G-PROTEINS Fungal pathogens after perceiving plant signals may transduce these signals using heterotrimeric guanine nucleotide-binding (G) proteins (Liu and Dean, 1997). The cell membrane-associated heterotrimeric G-proteins are key components in the signal transduction pathways.

Most germ tubes emerge from the spore body close to its site of contact with the host leaf so that the growing germ tubes are highly likely to make contact with the substratum. , 2000). , 2000) may play a role in perception of the plant-surface contact site and subsequent intracellular signaling systems controlling the site of germ tube emergence. The activation of intracellular signaling has been demonstrated by showing the fluctuations in cyclic adenosine monophosphate (cAMP) and protein kinase A (PKA) levels within developing B.
