ceratodon purpureus/sucrose

Nonsymbiotic hemoglobins (nsHbs) are widespread in plants including bryophytes. Bryophytes (such as mosses) are among the oldest land plants, thus an analysis of a bryophyte nsHb is of interest from an evolutionary perspective. However, very little is known about bryophyte nsHbs. Here, we report the

Moss protonemata exhibit negative gravitropism and the amyloplasts of the apical cell seem to play a key role in protonemal gravisensitivity. However, the mechanisms of this process are still poorly understood. Previously, we have shown that Ceratodon protonemata grown on agar-medium demonstrated

• Sexual reproduction in mosses requires that sperm be released freely into the environment before finding and fertilizing a receptive female. After release from the male plant, moss sperm may experience a range of abiotic stresses; however, few data are available examining stress tolerance of moss
