Resorption, however, may be curtailed by climatic events that cause rapid leaf death, such as severe drought, which has been projected to double by the year 2100 in the eastern United States. During a record drought in the southeastern US, we studied 18 common temperate winter-deciduous trees and shrubs to understand how extreme drought affects nutrient resorption of the macronutrients N, P, K, and Ca. Four species exhibited drought-induced leaf senescence and maintained higher leaf water potentials than the remaining 14 species (here called drought-evergreen species). This strategy prevented extensive leaf desiccation during the drought and successfully averted large nutrient losses caused by leaf desiccation. These four drought-deciduous species were also able to resorb N, P, and K from drought-senesced leaves, whereas drought-evergreen species did not resorb any nutrients from leaves lost to desiccation during the drought. For Oxydendrum arboreum, the species most severely affected by the drought, our results indicate that trees lost 50% more N and P due to desiccation than would have been lost from fall senescence alone. For all drought-deciduous species, resorption of N and P in fall-senesced leaves was highly proficient, whereas resorption was incomplete for drought-evergreen species. The lower seasonal nutrient losses of drought-deciduous species may give them a competitive advantage over drought-evergreen species in the years following the drought, thereby impacting species composition in temperate deciduous forests in the future.}, number={4}, journal={OECOLOGIA}, author={Marchin, Renee and Zeng, Hainian and Hoffmann, William}, year={2010}, month={Aug}, pages={845–854} }

Our previous study showed that ectopic expression of the PAP1 gene led to high pigmentation of anthocyanins in all tissues of transgenic tobacco plants. In order to understand the mechanisms of how PAP1 regulates anthocyanin biosynthesis and what can regulate the function of PAP1, we have established PAP1 transgenic tobacco callus cultures. Phenotypically different calli including anthocyanin-producing red and anthocyanin-free white calli lines were differentially induced from the same genotype of PAP1 transgenic plants. RT-PCR analysis showed that the expression of the PAP1 transgene was similar in the two types of calli, indicating that the transgenic red and white calli had differential responses to the regulation of PAP1. The growth of transgenic red calli followed a "sigmoid-like" curve in a 25-day callus culture period, during which the time course obviously impacted the profiles and the average levels of anthocyanins even though the expression of the PAP1 transgene was constitutive. A HPLC-UV-ESI-mass spectrum-based profiling characterized nine anthocyanin molecules (e.g., 595, 579 and 609 m/z) in the transgenic red calli over the course of the culture period. Cyanidin, pelargonidin, and peonidin were the major anthocyanidins identified by HPLC-mass spectrum analysis. We have demonstrated that dark, nitrogen nutrients, and auxin apparently affect the anthocyanin profiles in PAP1 transgenic callus cultures; and suggest that these cell cultures are an appropriate system to study the regulatory function of PAP1 on the anthocyanin biosynthesis at post-transcriptional level in vivo.}, number={1}, journal={Planta}, publisher={Springer Science and Business Media LLC}, author={Zhou, Li-Li and Zeng, Hai-Nian and Shi, Ming-Zhu and Xie, De-Yu}, year={2008}, month={Sep}, pages={37–51} }

The full-length cDNA encoding HDR, designated as GbHDR (Genbank Accession Number DQ364231), was isolated for the first time from G. biloba by RACE method. GbHDR contained a 1,422-bp open reading frame encoding 474 amino acids. The deduced GbHDR protein, showing high identity to HDRs of other plant species, was predicted to possess a chloroplast transit peptide at the N-terminal and four conserved cysteine residues. Two-dimensional structural analysis showed that GbHDR had a similar secondary structure with HDR from Arabidopsis thaliana. Southern blot analysis indicated that GbHDR belonged to a small gene family. Transcription pattern analysis revealed that GbHDR had high transcription in roots, and low in leaves and stems. The cloning of GbHDR gene will enable us to further understand the role of GbHDR involved in terpene triclatones biosynthetic pathway in G. biloba at molecular level.}, number={3}, journal={MOLECULAR BIOLOGY REPORTS}, author={Lu, Jie and Wu, Weisheng and Cao, Shuwen and Zhao, Henan and Zeng, Hainian and Lin, Ling and Sun, Xiaofen and Tang, Kexuan}, year={2008}, month={Sep}, pages={413–420} }

Through comparative analysis of pcl gene and its deduced amino acid sequence with those of other Araceae species, it was found that pcl encoded a precursor lectin with signal peptide. PCL is a mannose-binding lectin with three mannose-binding sites. Semi-quantitative RT-PCR analysis revealed that pcl is expressed in all tested tissues including leaf, stem and bulbil, but with the highest expression in bulbil.
