Plants are known for their capacity to regenerate the whole body through de novo formation of apical meristems from a mass proliferating cells named callus. Exogenous cytokinin and auxin determine cell fate establishment stem niche, which is vital step shoot regeneration, but underlying mechanisms remain unclear. Here, we show that type-B ARABIDOPSIS RESPONSE REGULATORs (ARRs), critical components signaling, activate transcription WUSCHEL (WUS), encodes key regulator maintaining cells. In...
Yellowhorn (Xanthoceras sorbifolium Bunge), a deciduous shrub or small tree native to north China, is of great economic value. Seeds yellowhorn are rich in oil containing unsaturated long-chain fatty acids that have been used for producing edible and nervonic acid capsules. However, the lack high-quality genome sequence hampers understanding its evolution gene functions.In this study, whole was sequenced assembled by integration Illumina sequencing, Pacific Biosciences single-molecule...
Abstract Background In plants, pollination is a critical step in reproduction. During pollination, constant communication between male pollen and the female stigma required for adhesion, germination, tube growth. The detailed mechanisms of stigma-mediated reproductive processes, however, remain largely unknown. Maize ( Zea mays L.), one world’s most important crops, has been extensively used as model species to study molecular interaction. A comprehensive analysis maize silk transcriptome...
ABSTRACT Salt stress is a major abiotic restrict plant growth and distribution. In our previous study, we found the ABI5‐BINDING PROTEIN 2a ( PagAFP2a ) gene was rapidly significantly induced by salt in hybrid poplar Populus alba × glandulosa ), however, its function responses unclear. this further demonstrated that expression ABA treatments. Additionally, ABA‐responsive element (ABRE) binding proteins (PagAREB1s) directly bind to promoter activate expression. Physiological analysis showed...
Angiosperm stigma supports compatible pollen germination and tube growth, resulting in fertilization seed production. Stigmas are mainly divided into two types, dry wet, according to the absence or presence of exudates on their surfaces. Here, we used 2DE MS identify proteins specifically preferentially expressed stigmas maize (Zea Mays, stigma) tobacco (Nicotiana tabacum, wet stigma), as well rinsed from surface stigma. We found that share similar distributions functional categories....
In angiosperms, successful pollen-pistil interactions are the prerequisite and guarantee of subsequent fertilization seed production. Recent profile analyses have helped elucidate molecular mechanisms underlying these processes at both transcriptomic proteomic levels, but involvement miRNAs in is still speculative. this study, we sequenced four small RNA libraries derived from mature pollen, vitro germinated silks, pollinated silks maize (Zea mays L.). We identified 161 known belonging to 27...
Abstract Molecular markers are efficient tools for breeding and genetic studies. However, despite their ecological economic importance, development application have long been hampered. In this study, we identified 524,170 simple sequence repeat (SSR), 267,636 intron length polymorphism (ILP), 11,872 potential (PIP) from 16 tree species based on recently available genome sequences. Larger motifs, including hexamers heptamers, accounted most of the seven different types SSR loci. Within these...
Plants are known for their capacity to regenerate organs, such as shoot, root and floral organs. Recently, a number of studies contributed understanding the mechanisms shoot regeneration. However, underlying organ regeneration largely unknown. In this study, we established carpel system in which two types carpels were induced by exogenous cytokinin. For type I, all organs regenerated inflorescence transformed into carpels. II, generated directly from callus. The transcript level AGAMOUS...
Yellowhorn ( Xanthoceras sorbifolium ) is an oil-bearing tree species growing naturally in poor soil. The kernel of yellowhorn contains valuable fatty acids like nervonic acid. However, the genetic basis underlying biosynthesis valued and adaptation to harsh environments mainly unexplored yellowhorn. Here, we presented a haplotype-resolved chromosome-scale genome assembly with size 490.44 Mb containing scaffold N50 34.27 Mb. Comparative genomics, combination transcriptome profiling analyses,...
Fine roots play important roles in the allocation of forest net primary productivity. Here, to provide insights into intrinsic and extrinsic factors affecting root growth, we examined morphology longevity different-order fine two poplar (Populus × euramericana (Dode) Guinier) plantations with contrasting productivities. The results indicated that biomass decreased significantly as orders increased (P < 0.05). In plantation relatively high productivity, specific length first- second-order...
Somatic cells of higher plants possess the remarkable ability to regenerate new individuals via reestablishing apical meristems. Reconstitution shoot meristem is vital process and required for application plant biotechnology. Under in vitro culture condition, can be formed directly or indirectly, depending on absence presence callus as intermediate status. However, difference regulatory mechanisms between two regeneration types remains unknown. In this study, we established a bi-directional...
LBD (LATERAL ORGAN BOUNDARIES DOMAIN) transcription factors are key regulators of plant growth and development. In this study, we functionally characterized PagLBD4 as an important regulator secondary cell wall biosynthesis in Populus. Overexpression (PagLBD4OE) significantly decreased height, stem diameter, leaf size Moreover, (SCW) deposition wood formation was suppressed PagLBD4OE plants. Consistent with the functional analysis, RNA sequencing (RNA-seq) analysis revealed that SCW pathways...
