Taxodium Rich is well known for its flooding tolerance and has great ecological economic potential. A comprehensive understanding of pollen characteristics storage capacity important breeding genetic resource conservation the genus. In this study, we observed microsporogenesis ornamentation, studied conditions in vitro germination, compared difference viability T. distichum var. measured by ger...
Differential screening of a mature Brassica campestris pollen cDNA library has identified five cDNA clones that represent transcripts expressed exclusively, or at elevated levels, in pollen. We show here that the expression of one of these, clone Bcp1, is tissue specific and temporally regulated. The gene is activated during microspore development, as detected by in situ hybridization. Expressi...
The genus Brachiaria contains species that have great economic importance in the Brazilian agricultural sector, as they enable cattle ranching on acid and poor soils with species that are resistant to spittlebugs and form crop-livestock-forest integration systems. The genus mainly consists of tetraploid (2n = 4x = 36) and apomictic species such as B. decumbens and B. brizantha. Sexuality is fou...
