Guangzhou researchers have teamed up with china scientists to successfully identify the Dt1 as a new negative regulator to control soybean seed weight that provide new insights into how soybean seed development responds to photoperiod at different latitudes .We unveiled a new mechanism of how seed weight is controlled by photoperiod in crops , offering an ideal genetic component for improving soybean ’ s yield by manipulating its seed weight and growth habit , " said HOU Xingliang .Which als...

Plant genetic transformation is essential for crop engineering and modern molecular breeding .The genetic and cytological results confirmed that efficient meristem transformation of and rapid transformant regeneration were the reasons for rapidly and efficiently obtaining stable transgenic plants .The RAPID method overcomes the limitations of traditional methods for achieving rapid   in planta   transformation , and can be potentially applied to a wide range of plant species that are capabl...

Meristems and root meristems .Mature seeds of plants contain plumule , epicotyl , radicle , and endosperm ( cotyledons in dicotyledonous plants ) , which.Most advantageous ways for large-scale seedling production of orchids at present .Research fields of efficient regeneration of orchids , genetic transformation , production of secondary metabolites , Cell engineering , etc .Developmental process in orchids are largely unknown .Utilization of orchids .In the Dendrobium orchid .

The timing of floral induction is tightly controlled by environmental cues and intrinsic signals. The critical role of gibberellin (GA) in this process has been extensively studied in the past decades. DELLA proteins serve as the central regulatory hubs of GA signaling. The mechanism of GA-dependent transcription involves the recruitment of DELLA proteins to transcription factors. In general, epigenetic modifiers are believed to cooperate with transcription factors to regulate gene expression...

Sweet potatoes ( Ipomoea batatas L . ) are an important cash crop in the world , and China is the world ' s largest producer , consumer , and exporter of sweet potatoes , accounting for more than 60% of the world ' s total production .Sweet potato weevils are the most harmful pests in sweet potato cultivation and are also important international quarantine pests , which cause great harm to sweet potatoes during planting and tuber storage by biting leaves and tubers .

Researchers from South China Botanical Garden of Chinese Academy of Sciences found an exogenous GA3 application promoted flowering of P . callosum by inducing its early bolting instead of the floral transition of dominant flowers .Article link : https : / / academic . oup . com/hr/advance-article/doi / 10.1093 / hr/uhac091/6572268 ? guestAccessKey = b24130c1 - a929-4 c94 - b716-147 ffb6e0a8f.

Due to internal resource restriction, plants have evolved an elaborate regulatory mechanism to modulate the tradeoff between growth and defense for survival under external stress. When attacked by pathogenic bacteria or insect pests, plants often devote more resource to activate defense response at the expense of growth

Prof . Zeng ’ s Team at South China Botanical Garden has made significant impact on the introduction , breeding , propagation , commercial production , conservation and molecular function in recent years .In particular , the Paphiopedilum breeding has been at the advanced level in the world . 15 species have been developed and approved by variety registration in Guangdong Province . 88 species been registered in Royal Horticultural Society ( RHS ) ." Paphiopedilum New Variety Research and De...

To develop sophisticated approaches for distinguishing goji origins , 325 wolfberry fruit samples of a certain cultivar , plant age , drying method and collection season were gathered from 26 producing areas across Northwest China in 2017 and.The indices selected in this study can distinguish gojis produced in Zhongning County from fruit originating from five other provinces with high repeatability , which was validated with various cultivars , drying methods .
