Comparative cytological and transcriptomic analysis of pollen development in autotetraploid and diploid rice [0.03%]
自四倍体与二倍体水稻花粉发育的细胞学和转录组比较分析
Jinwen Wu,Muhammad Qasim Shahid,Haibin Guo et al.
Jinwen Wu et al.
Autotetraploid rice has greater genetic variation and higher vigor than diploid rice, but low pollen fertility is one of the major reasons for low yield of autotetraploid rice. Very little is known about the molecular mechanisms of low poll...
OsMLO12, encoding seven transmembrane proteins, is involved with pollen hydration in rice [0.03%]
OsMLO12（编码七个跨膜蛋白）与水稻花粉吸水有关
Jakyung Yi,Suyoung An,Gynheung An
Jakyung Yi
Hydration is the first step in pollen germination. However, the process is not well understood. OsMLO12 is highly expressed in mature pollen grains; plants containing alleles caused by transfer DNA insertions do not produce homozygous proge...
Brassinosteroids promote Arabidopsis pollen germination and growth [0.03%]
brassinosteroid促进拟南芥花粉的萌发和生长
Frank Vogler,Christina Schmalzl,Maria Englhart et al.
Frank Vogler et al.
Pollen tubes are among the fastest tip-growing plant cells and represent an excellent experimental system for studying the dynamics and spatiotemporal control of polarized cell growth. However, investigating pollen tube tip growth in the mo...
Pistillate flower development and pollen tube growth mode during the delayed fertilization stage in Corylus heterophylla Fisch [0.03%]
辽核胡桃雌蕊发育及延迟受精阶段的花粉管生长方式研究
Jianfeng Liu,Huidi Zhang,Yunqing Cheng et al.
Jianfeng Liu et al.
Unlike most angiosperms, in which fertilization occurs within several days after pollination, fertilization in hazel (Corylus Spp.) is delayed by two to three and a half months. However, the female inflorescences or young fruits are too har...
Sucrose concentration in the growth medium affects the cell wall composition of tobacco pollen tubes [0.03%]
培养基中蔗糖浓度影响烟草花粉管细胞壁的组成
Giovanni Biagini,Claudia Faleri,Mauro Cresti et al.
Giovanni Biagini et al.
The cell wall of pollen tubes is organized in both spatial and temporal order to allow the pollen tube to grow according to external conditions. The deposition of methyl-esterified and acid pectins in addition to callose/cellulose occurs ac...
High humidity partially rescues the Arabidopsis thaliana exo70A1 stigmatic defect for accepting compatible pollen [0.03%]
高湿度部分补救拟南芥exo70A1突变体柱头接受兼容花粉的能力缺陷
Darya Safavian,Muhammad Jamshed,Subramanian Sankaranarayanan et al.
Darya Safavian et al.
We have previously proposed that Exo70A1 is required in the Brassicaceae stigma to control the early stages of pollen hydration and pollen tube penetration through the stigmatic surface, following compatible pollination. However, recent wor...
Transcriptional silencing of heterologous anther promoters in maize: a genetic method to replace detasseling for seed production [0.03%]
玉米异源花药启动子转录沉默：一种替代去雄的遗传方法以用于种子生产
A Mark Cigan,Kristin Haug-Collet,Joshua Clapp
A Mark Cigan
The promoter of the maize male fertility gene ZmMs45, and other anther-specific maize promoters, was previously shown to be transcriptionally silenced by constitutively expressed promoter-inverted repeat RNAs (pIRs). In addition, ZmMS45pIR-...
Functional redundancy and/or ongoing pseudogenization among F-box protein genes expressed in Arabidopsis male gametophyte [0.03%]
拟南芥雄配子体发育中F-box蛋白基因的功能冗余或假基因化现象分析
Sobia Ikram,Monique Durandet,Simona Vesa et al.
Sobia Ikram et al.
F-box protein genes family is one of the largest gene families in plants, with almost 700 predicted genes in the model plant Arabidopsis. F-box proteins are key components of the ubiquitin proteasome system that allows targeted protein degr...
Flower development in Coffea arabica L.: new insights into MADS-box genes [0.03%]
咖啡属植物阿拉伯咖普拉索斯种花发育的研究——MADS盒基因的新见解
Raphael Ricon de Oliveira,Igor Cesarino,Paulo Mazzafera et al.
Raphael Ricon de Oliveira et al.
Coffea arabica L. shows peculiar characteristics during reproductive development, such as flowering asynchrony, periods of floral bud dormancy, mucilage secretion and epipetalous stamens. The MADS-box transcription factors are known to cont...
Expression patterns of conserved microRNAs in the male gametophyte of loblolly pine (Pinus taeda) [0.03%]
落松(Pinus taeda)雄配子体中保守性微小RNA的表达模式
Christina R Quinn,Rie Iriyama,Danilo D Fernando
Christina R Quinn
MicroRNAs (miRNAs) are small RNAs that regulate genes involved in various aspects of plant development, but their presence and expression patterns in the male gametophytes of gymnosperms have not yet been established. Therefore, this study ...
