Background: Bulbs of the ornamental flower Lilium pumilum enter a period of dormancy after flowering in spring, and require exposure to cold for a period of time in order to release dormancy. Previous studies focused mainly on anatomical, physiological and biochemical changes during dormancy release. There are no dormancy studies of the northern cold-hardy wild species of Lilium at the molecula...

Gene flow between species may last a long time in plants. Reticulation inevitably causes difficulties in phylogenetic reconstruction. In this study, we looked into the genetic divergence and phylogeny of 20 Lilium species based on multilocus analyses of 8 genes of chloroplast DNA (cpDNA), the internally transcribed nuclear ribosomal DNA (nrITS) spacer and 20 loci extracted from the expressed se...

Não existem barreiras morfofisiológicas para o desenvolvimento das glândulas mamárias em machos, porém, fato de não amamentarem sua prole é intrigante e tem levantado inúmeras questões há muito tempo. Relatamos primeiro registro lactação machos na espécie Sturnira lilium um indivíduo capturado Mata Atlântica brasileira. O apresentou as mesmas características morfológicas externas encontradas fê...

one of the most effective ways to propagate lilium is by using tissue culture techniques, preferably through bulblet production. in addition to the surviving percentage of lilium bulbs after transplantation, the small size of in vitro bulblets compared to commercial bulbs and bulblets‟ dormancy are the most important constraints to commercializing lilium micropropagation. different concentratio...

Due to the scarcity of information about patterns of spermatogenesis in bats, this study aimed to provide information on the testicular activity of the bat Sturnira lilium along the annual seasons. Thus, a series of morphometrical and stereological analyses were made using the testes of adult S. lilium in order to achieve a better understanding of the sperm production dynamics. Light and transm...

As a devastating holoparasitic weed, Orobanche aegyptiaca Persoon. (Egyptian broomrape) causes serious damage to agricultural production and threatens economic development, which has raised widespread concern. The present study was conducted to determine whether lilies have the potential to be used as 'trap crops' for controlling O. aegyptiaca Persoon. In the experiments, the ability of three p...

The phosphatidylinositol-specific phospholipase C (PI-PLC) activity is detected in purified Lilium pollen protoplasts. Two PI-PLC full length cDNAs, LdPLC1 and LdPLC2, were isolated from pollen of Lilium daviddi. The amino acid sequences for the two PI-PLCs deduced from the two cDNA sequences contain X, Y catalytic motifs and C2 domains. Blast analysis shows that LdPLCs have 60-65% identities t...

Bats can be monoestrous or polyestrous, and seasonal or non-seasonal in their reproductive patterns. The strategy adopted by each species or population depends on the regional climate. The objective this study was to analyze reproductive data of Sturnira lilium from long-term sampling carried out in several sites in Rio de Janeiro states, southeastern Brazil. We carried out sampling in 42 sites...
