中文拼音 [pèizibāozi]
配子孢子
英文
gametospore-
Ascospore analysis suggested that the fungus is homothallic but will preferentially outcross.
從分析子囊孢子的結果看出,此菌能同親配合,但很易異型雜交。Like thallose liverworts, the hornworts have an alternation of generations in which the gametophyte is a dorsiventral flattened green phallus and the saprophyte is an upright structure that has a foot embedded in the gametophytes, from which it draws nutrition

在維管植物(蕨類)中二倍體的孢子體占生活史的主要部分,配子體僅為原葉體。Protonema ( pl. protonemata ) the young bryophyte gametophyte that develops following spore germination. the mature gametophyte plants develop from buds that form at several points along the protonema
原絲體:苔蘚植物中直接由孢子萌發形成的結構稱為原絲體。原絲體上形成1個或幾個芽體,芽體進一步發育為配子體。Sporogonium the sporophyte generation in mosses and liverworts. it develops from the zygote and comprises the foot, seta, and capsule. the sporogonium is parasitic on the gametophyte generation
孢子體:為苔蘚和地錢的孢子體世代具有。由受精卵發育而來,包括基足、柄和孢蒴。孢子體是寄生在配子體上的。The gametes fuse to form a zygote, which develops into the sporophyte, and the spores germinate and produce the gametophyte, so forming a cycle
配子融合產生合子,進而發育為孢子體,孢子萌發產生配子體,形成一個循環。The haploid plant produces gametes mitotically and is thus termed the gametophytes while the diploid plant produces spores meiotically and is called the sporophyte
單倍體植物有絲分裂產生配子體,二倍體減數分裂產生孢子體。In bryophytes ( mosses, liverworts and horworts ) the haploid gametophyte is the dominant phase of the life cycle and the sporophyte is represented only by the capsule, seta, and foot
在苔蘚類植物中(苔蘚,地錢,金魚藻)單倍的配子體占生活史的主要部分,孢子體包括孢蒴、蒴柄和基足。Examples include male and female plants in dioecious species, aerial and submerged leaves, alternation of gametophyte and sporophyte stages of a life cycle, and mesophyll and bundle - sheath chloroplasts
例如在雌雄異株物種中的雌性植物和雄性植物,氣生的和被水浸沒的葉片,生活史中的配子體與孢子體的交替,葉肉和維管束鞘葉綠體等。Hofmeister aso showed that the gametophytes and sporophytes of seed - bearing plants were homologous with those of ferns and mosses and that the gymnosperms formed a plant group between the latter and the angiosperms
他認為種子植物的孢子體和配子體與蕨類以及苔蘚類是同源的,還指出裸子植物形成了一個單獨的組群,它是位於蕨類植物與被子植物之間的一個植物類群。Strains of rhizopus stolonifer ( ehrenb. : fr. ) vuill. isolated from taiwan were crossed to produce zygospores in the laboratory condition
摘要由本省分離之匍枝根?在實驗室中經交配有接合孢子形成。In this paper, the whole process of it microsporogenesis and male gametophytes development was observed with microscope to sure weather stamen development is normal. at the same time, in order to provide techniques on biotechnology conservation and the foundation of its resources gene pool in cell engineering, its techniques on culture in vitro was studied
本論文通過對蝟實小孢子發生和雄配子體發育全過程進行細胞觀察,探尋蝟實的雄性器官的發育是否是蝟實有性生殖的薄弱環節,並對蝟實的離體培養進行了初步的研究,為蝟實生物技術保存、建立蝟實種質資源基因庫提供細胞工程方面的途徑和技術。In sporophytically self - incompatible brassica, three s - linked genes, the pollen ligand scr, stigma receptor slg and srk, have been identified. in addition, four genes ( arc1, thl1, thl2 and mod ) that do not link to s locus have also been found, they are regarded as downstream protein factors of self - incompatibility ( si ) response, however, their biological function is not clear
在孢子體型自交不親和的蕓薹屬中,已經鑒定出3個主要與s位點緊密連鎖的基因,花粉中的配體scr和柱頭中的受體slg與srk :另外鑒定出4個不與s位點連鎖的基因arc1 、 thl1 、 thl2和mod ,它們被認為是si反應的下游蛋白質因子,但是對它們的生物學功能了解的還比較少。The macrosporogenesis and female gamephyte development of psathyrostachys huashanica
