Abstract In Solanaceae, the self-incompatibility S-RNase and S-locus F-box interactions define self-pollen recognition rejection in an S-specific manner. This interaction triggers a cascade of events involving other gene products unlinked to that are crucial response. To date, two essential pistil-modifier genes, 120K High Top-Band (HT-B), have been identified Nicotiana species. However, biochemistry genetics indicate additional modifier genes required. We recently reported Kunitz-type...
Abstract The high prevalence of dioecy in marine angiosperms or seagrasses (>50% all species) is thought to enforce cross‐fertilization. However, are clonal plants, and they may still be subject sibling‐mating bi‐parental inbreeding if the genetic neighborhood smaller than size genets. We tested this by determining neighborhoods dioecious seagrass Thalassia testudinum at two sites (Back‐Reef Mid‐Lagoon) Puerto Morelos Reef Lagoon, Mexico, measuring dispersal pollen seeds situ, fine‐scale...
After landing on a wet stigma, pollen grains hydrate and germination generally occurs. However, there is no certainty of the tube growth through style to reach ovary. The pistil gatekeeper that evolved in many species recognize reject self-pollen, avoiding endogamy encouraging cross-pollination. recognition complex process, specific factors are needed. Here isolation characterization stigma-specific protein from N. alata, NaStEP (N. alata Stigma Expressed Protein), homologous Kunitz-type...
A photoacoustic technique was used as an alternative method to monitor the crater volume and its role in emission line intensification double-pulse pre-ablation configuration. The measured using confocal microscopy correlated with changes signal. Laser spectroscopy characterize enhancement a function of delay between lasers first pulse energy. Optimum found be microsecond timescale corresponding maximum largest change single- signals. Only slight detected increasing energy above ablation...
In order to increase our embryological knowledge of Pereskia, a genus considered the earliest member Cactaceae, we followed development flowers and seeds Pereskia lychnidiflora, species from southeastern Mexico. We compared data with that available other closely related members in family. The characterization showed basic features are homogeneous across family supported placement P. lychnidiflora as one two clades, sister remaining cacti. Our also supports hypothesis within evolutionary...
Even though seagrasses are clonal plants, they also invest substantial energy in sexual reproduction. However, little is known about the development of reproductive structures and their complex interactions with ambient conditions. Here, we describe structural physiological changes during fruit pericarp tropical seagrass Thalassia testudinum, possible role defense mechanisms. The exocarp develops protuberances a monostratified epidermis. parenchyma below epidermis, consists chlorenchyma...
La proximidad de los órganos sexuales en las flores hermafroditas incrementa considerablemente la probabilidad autofecundación. Para evitarla, varias especies desarrollaron el sistema incompatibilidad sexual (SI), mecanismo presente familias angiospermas que permite al pistilo rechazar polen propio y aceptar plantas genéticamente diferentes. Esto evita endogamia favorece polinización cruzada. SI está controlada por un locus muy polimórfico llamado S incluye dos unidades transcripcionales...
