The accumulation of phytic acid during development of lily (Lilium longiflorum Thunb.) pollen and its degradation during germination have been studied. A substantial amount of phytic acid accumulates in lily pollen by 5 days before anthesis, and little change occurs during subsequent maturation. Mature lily pollen contains 7 to 8 micrograms phytic acid per milligram pollen. Considerable degrada...

Lily pollen was developed to express HBsAg by Agrobacterium-mediated transformation. A double prime-boost strategy combining parenteral and oral HBsAg boosters was found to increase antibody titer levels 10-fold, as compared to a single process of priming and boosting. Lily pollen may prove a tool for oral vaccine development.

MicroRNAs, as master regulators of gene expression, have been widely identified and play crucial roles in plant-pathogen interactions. A fatal pathogen, Botrytis elliptica, causes the serious folia disease of lily, which reduces production because of the high susceptibility of most cultivated species. However, the miRNAs related to Botrytis infection of lily, and the miRNA-mediated gene regulat...

Figure 1: Thoracic tomodensitometry at hospital admission, showing the garfish sword in the right hemithorax apex. When the garfish sword got stuck in his body, it might have generated serious internal injuries. As a result, removing such a foreign object could have been dangerous because of so many sharp teeth. This CT-scan shows it did not damage neither the nerves nor the vessels. Figure 2: ...

Previous studies aimed at detecting costs of sexually selected traits have yielded mixed results partly because of variable methods. We present a novel approach: a repeated-measures design to examine individual variation in locomotor performance of male Xiphophorus hellerii as the sexually selected sword develops ontogenetically and to determine whether the growth of a sexually selected trait a...

Female mating preferences can be secondarily lost for a number of reasons. We examined the preference of female pygmy swordtails, Xiphophorus nigrensis, for the sword, a conspicuous extension of the caudal fin in some males. Females failed to show a preference for conspecific males with swords when presented with live males naturally varying in sword length, with live males of manipulated sword...

Purpose ‐ To describe the repository deposit protocol, Simple Web‐service Offering Repository Deposit (SWORD), its development iteration, and some of its potential use cases. In addition, seven case studies of institutional use of SWORD are provided. Approach ‐ The paper describes the recent development cycle of the SWORD standard, with issues being identified and overcome with a sub...

Swordtail fish (Poeciliidae: genus Xiphophorus) are a paradigmatic case of sexual selection by sensory exploitation. Female preference for males with a conspicuous "sword" ornament is ancestral, suggesting that male morphology has evolved in response to a preexisting bias. The perceptual mechanisms underlying female mate choice have not been identified, complicating efforts to understand the se...
