“…The mechanism underlying the rapid growth of bamboo shoots is a hot research topic. However, most works have focused on the molecular regulatory mechanism in order to identify the related genes (Peng et al, 2013;Yeh et al, 2013). The anatomical and physiological characteristics of young shoots during their rapid growth have been neglected.…”

The physiological function of bamboo shoot sheaths is still unclear. In the present study, we investigated the anatomical and physiological influences of bamboo shoot sheaths on internode elongation by longitudinally striping parts of sheaths. The internodes would bend toward the bare sides during night. The results showed that amounts of water leaked at the cut of shoot sheaths during night, which impeded the increase of water, water pressure and assimilate transport rates, and decreased starch and soluble sugar catabolism in the bare side of the internodes. A higher level of water pressure and sugar metabolism increased the vacuole expansion and promoted the cell expansion in the outer sides as compared to the bare sides. The bending growth of internodes was mainly due to the significant differences in cell expansion, which was led by the difference in water pressure and sugar hydrolysis levels between the inner and outer sides. Bamboo internode elongation mainly relied on the increase of water pressure and soluble sugar concentration. Shoot sheaths played an important role in the rapid growth of bamboo shoots as a controller in water and assimilate transportation. This study gave a new insight into understanding the rapid growth mechanism of bamboo plants.

“…The mechanism underlying the rapid growth of bamboo shoots has become an important research topic. Some studies have focused on the molecular regulatory mechanism of rapid growth to identify genes related to rapid growth (Cui et al 2012;Peng et al 2013;Yeh et al 2013). The morphological and physiological characteristics of bamboo shoots that may be involved in rapid growth, as well as the physiological functions of culm sheaths, have been neglected.…”

Culm sheath is an important morphological characteristic of bamboos; however, its physiological functions are still unknown. The main goal of this study was to examine the physiological functions of culm sheaths and their effects on the height growth of Fargesia yunnanensis Hsueh et Yi shoots. The elongating internodes were analyzed for determining the soluble sugar and starch contents, as well as the water potential of different sections. The transpiration rates were also determined and compared between culm sheaths and foliage leaf blades. The effects of culm sheaths on the shoot height growth were also analyzed. The results showed that the outer zone had higher starch but lower soluble sugar contents than the inner zone in the developing shoots. The transpiration rate of culm sheaths was far higher than that of leaves. The water potential of the outer zone was lower than that of the inner zone in bamboo culms. The growth of bamboo culms decreased without culm sheaths. When one strip of culm sheaths was peeled off longitudinally from young culms, the bare side of the culms curved rapidly after one night, and the water potential gradient between the inner and outer zones significantly decreased, further demonstrating that sheaths have significant effects on bamboo culm height growth.

“…The stem elongation was contributed to by the division and expansion of individual internodes [ 37 ]. Transcriptome analysis revealed that multiple signaling pathways, including GA, auxin, and ABA, may play a role in regulating internode elongation [ 38 ]. GA plays an antagonistic regulatory role in regulating internode stem elongation in rice [ 39 ].…”

Basic helix–loop–helix (bHLH)/HLH transcription factors are involved in various aspects of the growth and development of plants. Here, we identified four HLH genes, PePRE1-4, in moso bamboo plants that are homologous to Arabidopsis PRE genes. In bamboo seedlings, PePRE1/3 were found to be highly expressed in the internode and lamina joint by using quantitative RT-PCR analysis. In the elongating internode of bamboo shoots, PePRE genes are expressed at higher levels in the basal segment than in the mature top segment. Overexpression of PePREs (PePREs-OX) in Arabidopsis showed longer petioles and hypocotyls, as well as earlier flowering. PePRE1 overexpression restored the phenotype due to the deficiency of AtPRE genes caused by artificial micro-RNA. PePRE1-OX plants showed hypersensitivity to propiconazole treatment compared with the wild type. In addition, PePRE1/3 but not PePRE2/4 proteins accumulated as punctate structures in the cytosol, which was disrupted by the vesicle recycling inhibitor brefeldin A (BFA). PePRE genes have a positive function in the internode elongation of moso bamboo shoots, and overexpression of PePREs genes promotes flowering and growth in Arabidopsis. Our findings provided new insights about the fast-growing mechanism of bamboo shoots and the application of PRE genes from bamboo.
