Abstract
Moso bamboo (Phyllostachys edulis) is the most important monopodial bamboo species worldwide. Without a genetic transformation system, it is difficult to verify the functions of genes controlling important traits and conduct molecular breeding in moso bamboo. Here, we established a plant regeneration system from immature embryos. Calli were induced on MS medium added 4-6 mg⋅L-1 2,4-dichlorophenoxyacetic acid (2,4-D) with high efficiency (>60%). A plant growth regulator combination of 0.5 mg⋅L-1 1-naphthylacetic acid (NAA), 2.0 mg⋅L-1 6-benzylaminopurine (BAP), and 3.0 mg⋅L-1 zeatin (ZT) was suitable for shoot differentiation, and the shoot induction frequency was increased to 43% after 0.5 mg⋅L-1 abscisic acid (ABA) pretreatment. An effective antibiotic screening concentration was determined by hygromycin sensitivity test. We further optimized the Agrobacterium concentration and added vacuum infiltration for infection, which improves the transient expression efficiency. A genetic transformation system was established for the first time in moso bamboo, with the transformation efficiency of approximately 5%. To optimize genome editing, two endogenous U3 small nuclear RNA (snRNA) promoters were isolated and used to drive small guide RNA (sgRNA) expression. The results showed that the PeU3.1 promoter exhibited higher efficiency, and it was used for subsequent genome editing. Finally, homozygous pds1pds2 mutants were obtained by an efficient CRISPR/Cas9 genome-editing system. These technical systems will be conducive to gene functional validation and accelerate the molecular breeding process of moso bamboo.

An Efficient Plant Regeneration and Transformation System of Ma Bamboo ( Dendrocalamus latiflorus Munro) Started from Young Shoot as Explant. FRONTIERS IN PLANT SCIENCE 2017; 8:1298.

Abstract
Genetic engineering technology has been successfully used in many plant species, but is limited in woody plants, especially in bamboos. Ma bamboo (Dendrocalamus latiflorus Munro) is one of the most important bamboo species in Asia, and its genetic improvement was largely restricted by the lack of an efficient regeneration and transformation method. Here we reported a plantlet regeneration and Agrobacterium-mediated transformation protocol by using Ma bamboo young shoots as explants. Under our optimized conditions, embryogenic calluses were successfully induced from the excised young shoots on callus induction medium and rapidly grew on callus multiplication medium. Shoots and roots were regenerated on shoot induction medium and root induction medium, respectively, with high efficiency. An Agrobacterium-mediated genetic transformation protocol of Ma bamboo was established, verified by PCR and GUS staining. Furthermore, the maize Lc gene under the control of the ubiquitin promoter was successfully introduced into Ma bamboo genome and generated an anthocyanin over-accumulation phenotype. Our methods established here will facilitate the basic research as well as genetic breeding of this important bamboo species. Key achievements: A stable and high efficiency regeneration and Agrobacterium-mediated transformation protocol for Ma bamboo from vegetative organ is established.

Abstract
By using shoot tips as explants, various media and culture conditions for callus induction and proliferation, shoot differentiation, root induction and plantlet transplantation to develop an efficient and reliable regeneration system with Dendrocalamus hamiltonii were tested. Murashige and Skoog (MS) medium supplemented with 3 mg/l 2, 4-dichlorophenoxyacetic acid, 1 mg/l benzyladenine (BA), 500 mg/l glutamine, 500 mg/l proline, and 500 mg/l casein hydrolysate yielded the best rates of callus induction and granular-compact callus induction. MS medium supplemented with 1 mg/l BA, 0.3 mg/l kinetin and 0.3 mg/l naphthaleneacetic acid conferred the highest differentiation rate of calli. The maximum rooting rate was obtained in 1/2 MS medium supplemented with 3 mg/l indole-3-butyric acid, and the roots were long and thick. All hardened plantlets survived after transfer to an equal ratio mixture of peat, vermiculite and perlite. The regeneration system of D. hamiltonii developed is efficient and provides a useful tool for genetic transformation in bamboo species.

Abstract
Moso bamboo [Phyllostachys heterocycla var. pubescens (Mazel ex J. Houz.) Ohwi] is one of the most important forest crops in China and the rest of Asia. Although many sympodial bamboo tissue culture protocols have been established, there is no protocol available for plantlet regeneration as indicated by callus induction for monopodial bamboos, such as Moso bamboo. In the present report, embryogenic callus induction, embryoid development, and germination were established for Moso bamboo from zygotic seed embryos. Callus was initiated from zygotic embryos after 10-20 d culture on MS media supplemented with 4.0 mg/L 2, 4-D and 0.1 mg/L zeatin (ZT). About 50% of the explants produced calli, and nearly 15% of the calli were found to be embryogenic in nature. These embryogenic calli can be subcultured for proliferation in the Murashige and Skoog media (MS) supplemented with 0.5-2.0 mg/L 2, 4-D. These calli were found to have maintained their capacity for regeneration even after one year of subculture. The viable somatic embryoids regenerated in medium containing 5.0-7.0 mg/L ZT. Nearly 5% of the calli were found capable of regenerating into plantlets directly in MS medium containing 5.0-7.0 mg/L ZT. Root growth was more pronounced when the plantlets were transferred to medium containing 2.0 mg/L NAA. After 30 days of subculture, the plantlets were transferred to a greenhouse.

Abstract
Bamboos (family Poaceae) are the most beautiful and useful plants on the Earth, mainly found in the tropical and sub-tropical regions of the world. Bamboos are fast growing and early maturing, but lack of proper management of bamboo resources is leading to rapid reduction of the existing bamboosetum. Bamboo propagation through seeds is limited due to long flowering cycle of upto 120 years, seed sterility and short seed viability. Infrequent and unpredictable flowering events coupled with peculiar monocarpic behaviour i.e. flowering once before culm death, and extensive genome polyploidization are additional challenges for this woody group. Similarly, vegetative propagation by cuttings, offsets and rhizomes are also inadequate to cope up with the demand of planting stock due to large propagule size, limited availability, seasonal dependence, low multiplication rate and rooting percentage. Therefore, attempts have been made to propagate bamboos through in vitro techniques. In vitro flowering has also been achieved successfully in some bamboo species. Classification systems proposed to date need further support, as taxonomic delineation at lower levels is still lacking sufficient resolution. Tremendous advancement in molecular markers holds the promise to address the needs of bamboo taxonomy (systematics and identification) and diversity studies. Successful application of molecular marker techniques has been achieved in several bamboo species although, more studies are required to understand the population structure and genetic diversity of bamboos in a better way. In addition, some efforts have also been made to clone important genes from bamboos and also for genetic transformation using Agrobacterium and particle bombardment methods. An overview of the recent developments made in improvement of bamboos through in vitro propagation, molecular marker technologies, cloning, and transformation and transgenics has been presented. The future potential of improvement of bamboos using modern biotechnological tools has also been discussed.

Abstract
An accelerated protocol for large-scale propagation of Dendrocalamus asper, an edible bamboo, has been described. Seven axillary shoots were induced in vitro from each excised tender node (15-20 mm in length) containing single axillary bud when nodal segments were inoculated in semisolid Murashige and Skoog (MS) medium fortified with 5 mg/l 6-benzylaminopurine (BAP). Maximum multiple shoot formation (14) was observed when in vitro generated axillary shoots were transferred to liquid MS medium containing 5 mg/l BAP and 40 mg/l adenine sulphate. A maximum of 93.33 % shoots were effectively rooted when transferred to liquid MS medium supplemented with 1 mg/l indole-3-biutyric acid (IBA). A simple acclimatization procedure of 55 days, primarily in cocopeat for 20 days and finally in a blend of sand, soil and farm yard manure (1:1:1 v/v), ensured a very high survival rate within next 35 days. After acclimatization, rooted plantlets were further multiplied by splitting of rhizomes, formed in vivo within 90 days of growth. After 90 and 180 days of acclimatization, plants were successfully transferred to the field and maintained in an unirrigated condition with the initial supplementation of farm yard manure @ 10 kg/pit; where around 85 % survivability with 25 culms per bush attaining an average height of 4.5 m was recorded up to four years.

Abstract
An efficient protocol for in vitro propagation of Thamnocalamus spathiflorus (Trin.) Munro, an evergreen temperate bamboo, through multiple shoot formation from zygotic embryos excised from germinating seeds, as well as from nodal explants taken from a 2-year-old plant has been developed. Multiple shoot formation was standardized in both the cases on Murashige and Skoog (MS) medium supplemented with 5.0 µM 6-benzylaminopurine (BAP) and 1.0 µM indole-3-butyric acid (IBA). Clumps of three to four microshoots when transferred to plant growth regulator-free medium following 14 days' initial culture on medium supplemented with 150.0 µM IBA, resulted in 100% rooting with five to 12 roots per rooted plant. Then, 18 months following the transfer of in vitro propagated plants into earthen pots containing soil and growth under outdoor conditions, gas and water vapour exchange rates were measured at different light levels (0, 100, 500, 1000, 1500, 2000 µmol(-2) s(-1)), and compared with seedlings of the same age. Light optima for photosynthesis were recorded approximately 1000 µmol m(-2) s(-1) in in vitro propagated plants as well as seedlings. Water use efficiency increased with increase in the light intensity up to 1000 µmol m(-2) s(-1) and then decreased subsequently at higher light intensities. Stomatal conductance and transpiration also increased with the increase in light intensity up to 2000 µmol(-2) s(-1). Intercellular CO(2) concentration (C(i)) and the ratio of intercellular CO(2) concentration to ambient CO(2) (C(i)/C(a)) decreased with the increase in light intensity up to 500 µmol(-2) s(-1) and then reached nearly constant levels at higher light intensities. The results show that in vitro propagated and hardened plants of T. spathiflorus are morphologically as well as functionally comparable to seed raised plants of the same age, within the limits of this study.

Abstract
Young inflorescence explants of green bamboo (Bambusa oldhamii Munro) in culture show a high capacity for plant regeneration through somatic embryogenesis. Embryogenic callus was initiated from explants maintained on Murashige and Skoog's medium supplemented with 3 mg/l 2,4-D, 2 mg/l kinetin and a high content (60 g/l) of sucrose. Prolonged culture in the embryoid induction medium or transferral of embryonic callus to auxin-free medium resulted in the continued development and eventual germination of embryoids and establishment of rooted plantlets that were successfully transferred to soil.
