Ectopic expression of a poplar gene NAC13 confers enhanced tolerance to salinity stress in transgenic Nicotiana tabacum
Ectopic expression NAC13 gene Salt tolerance Transcription factor Transgenic tobacco
2024/1/11
NACs are one of the major transcription factor families in plants which play an important role in plant growth and development, as well as in adverse stress responses. In this study, we cloned a salt-...
Characterization of the TaALMT1 Protein as an Al3 t-activated Anion Channel in Transformed Tobacco ( Nicotiana Tabacum L.) Cells
ALMT1 Anion channel Aluminium Malate Al3 t-gated Patch-clamp
2015/2/5
TaALMT1 encodes a putative transport protein associated with Al3 t-activated efflux of malate from wheat root apices. We expressed TaALMT1 in Nicotiana tabacum L. suspension cells and conducted a deta...
Reduced tillage for tobacco (Nicotiana tabacum L.) production in East Cuba. Soil physical properties and crop yield
soil conditions tobacco production
2014/10/28
The area devoted to growing tobacco (Nicotiana tabacum L.) in the province of Granma, Cuba, accounted for nearly 2600 ha in the year 1997, which represented the 4% of the total tobacco plantation area...
Effects of cultural practices on weed flora in Virginia (flue-cured) organic tobacco (Nicotiana tabacum L.): green manure and irrigation systems
Allelopathy drip irrigation green manure organic tobacco sprinkler irrigation weed flora
2010/10/29
Organic tobacco is a new industrial crop. Field experiments were conducted, during 2005-2006, to determine the effects of irrigation system and green manure on weed flora in organic tobacco crops (Nic...
以云南种植面积较广的烟草品种K326作为供试材料进行盆栽种植,选择云南烟叶主产的玉溪烟区种植烤烟海拔最高的通海县(1806米)为试验点,通过在自然条件分别减弱25%(T1)、50%(T2)和65% (T3)的太阳UV-B辐射,研究同一种植地不同UV-B辐射对烤烟中部叶片发育过程中SOD、POD和CAT活性动态变化的影响。结果表明:T1和T3处理对烤烟SOD活性没有大的影响,但能减轻叶片衰老时的氧化...
烟草(Nicotiana tabacum L.)小孢子胚胎发生系统,不仅可以提供大量可供处理的小孢子胚,还由于小孢子胚胎发生的不同步性,可同时提供从2-3细胞原胚到分化胚一系列胚胎以供研究.利用这一便利系统,探讨了外源生长素处理对小孢子胚胎发育的影响.使用3种浓度的IAA:1、3、10 μmol/L,分别对不同发育时期烟草小孢子胚进行了处理,结果发现,对不同发育时期的小孢子胚,生长素处理的效果明显...
烟草(Nicotiana tabacum L.)的建议生长阶段划分及鉴定要素。
烟草(Nicotiana tabacum L.)花粉胚状体染色体加倍的研究
烟草
2008/1/10
本研究从寻求提高花粉植株加倍频率和性状表达能力的途径出发,进行了三年四批次对比试验,取得如下主要结果:(1)、花药培养至药室开裂、肉眼能见白色胚状体时,转移至吸饱0.2%秋水仙液的无菌脱脂棉上,处理72小时或长一些时间然后转上培养基,这样能取得60%的加倍效果。(2)、用注射器将灭菌的0.2%秋水仙液滴入开裂而见胚状体的药囊中,这样分化出的烟苗,加倍频率亦能达30%。(3)、无论(1)或(2)加倍...
