Integrative effect of drought and low temperature on litchi (Litchi chinensis Sonn.) floral initiation revealed by dynamic genome-wide transcriptome analysis

Scientific Reports (2016)

Jiyuan Shen Qiusheng Xiao Haiji Qiu Chengjie Chen Houbin Chen

Floral induction in litchi is influenced by multiple environment cues including temperature and soil water condition. In the present study, we determined that a combined treatment consisting of 14-day drought imposed prior to exposure to 35-day low temperature (T3) significantly promoted litchi flowering relative to the low temperature alone (T2), suggesting an integrative effect of drought and low temperature on litchi floral initiation. Analysis of transcriptomic changes in leaves from different treatments showed that 2,198 and 4,407 unigenes were differentially expressed in response to drought and low temperature, respectively. 1,227 of these unigenes were expressed in response to both treatments, implying an interaction of drought and low temperature on expression of genes involved in litchi floral initiation. Additionally, 932 unigenes were consistently differentially expressed during floral induction between T2 and T3 plants, which potentially accounts for the difference of flowering time. Thirty-eight transcription factors out of these 932 unigenes were identified as hub genes with central roles in regulation of litchi floral induction. The expression of litchi homologs of well-known flowering genes was also investigated, and one Flowering Locus T (FT) homolog may play a crucial role in litchi flowering in responses to drought and low temperature.

Expression and distribution of extensins and AGPs in susceptible and resistant banana cultivars in response to wounding and Fusarium oxysporum

Scientific Reports (2017)

Yunli Wu Wei Fan Xiaoquan Li Houbin Chen Tomáš Takáč

Abstract Banana Fusarium wilt caused by Fusarium oxysporum f. sp. cubense (Foc ) is soil-borne disease of banana ( Musa spp.) causing significant economic losses. Extensins and arabinogalactan proteins (AGPs) are cell wall components important for pathogen defence. Their significance for Foc resistance in banana was not reported so far. In this study, two banana cultivars differing in Foc sensitivity were used to monitor the changes in transcript levels, abundance and distribution of extensins and AGPs after wounding and Foc inoculation. Extensins mainly appeared in the root cap and meristematic cells. AGPs recognized by JIM13, JIM8, PN16.4B4 and CCRC-M134 antibodies located in root hairs, xylem and root cap. Individual AGPs and extensins showed specific radial distribution in banana roots. At the transcript level, seven extensins and 23 AGPs were differentially expressed between two banana cultivars before and after treatments. Two extensins and five AGPs responded to the treatments at the protein level. Most extensins and AGPs were up-regulated by wounding and pathogen inoculation of intact plants but down-regulated by pathogen attack of wounded plants. Main components responsible for the resistance of banana were MaELP - 2 and MaPELP - 2 . Our data revealed that AGPs and extensins represent dynamic cell wall components involved in wounding and Foc resistance.

RNA-seq analysis of apical meristem reveals integrative regulatory network of ROS and chilling potentially related to flowering in Litchi chinensis

Scientific Reports (2017)

Xingyu Lu Jingjing Li Houbin Chen Jiaqi Hu Pengxu Liu

Litchi is an important woody fruit tree. Floral initiation in litchi is triggered by low temperatures. However, defective flowering is a major challenge for litchi production in times of climate change and global warming. Previous studies have shown that the reactive oxygen species (ROS) generated by methyl viologen dichloride hydrate (MV) promotes flowering. In this study, potted trees were transferred to growth chambers for low-temperature (LT), medium-temperature (MT), and high-temperature (HT) treatments. Trees at MT were subjected to ROS treatment to promote flowering, and those at LT were induced to flower. RNA-sequencing was applied to obtain a global transcriptome of the apical meristem and reveal potential gene networks controlling the transformation from vegetative meristems (VM) into inflorescence meristems (IM). We assembled 73,117 unigenes with a mean size of 790 bp and 11741 unigenes were identified as both chilling and ROS responsive genes (CRRGs), of which 48 were identified as flowering-related CRRGs, 59 were plant hormone signal transduction CRRGs, and 146 were plant hormone biosynthesis-related CRRGs. Genes co-expression network analysis indicated inner relationships, suggesting that ROS and chilling promotes the VM to IM transition through a regulatory gene network of transcription factors, hormones, and flowering regulators.
