查询词典 carpels

Apocarpy An ovary made up of unfused carpels, as in the buttercup.

离生心皮：由未愈合的心皮构成的子房。

Ovary 2-locular, carpels free at apex; ovules mostly 1 per carpel, less often many, but then most of them sterile, crassinucellar, bitegmic, anatropous, halfway between apotropous and epitropous, pendent from ovary top if solitary, along the carpellary margins if numerous; placentation axile.

Carpels 2(or 3),± connate or free; ovary subsuperior or semi-inferior, 2(or 3)-loculed with axile placentation or 1-loculed with marginal placentation; ovules many.

心皮2(或3)，多少合生或离生；子房半上位或半下位，2室具中轴胎座或室具边缘胎座式；胚珠很多。

Carpels (3-)5(-15), seemingly free but basally connate, each with one ovule.

心皮(3-)5(-15)，好象离生但是基部合生，其中每个一胚珠。

Ovary 2- or 3(-5)-carpellate; styles distinct or basally united, as many as carpels.

雄蕊5。子房具心皮2或3 (-5)；花柱离生的或基部合生，同数心皮。

Carpels united by a filiform style; ovules numerous, biseriate on each placenta.

通过一种丝状的风格的心皮合生；胚珠多数，在每胎座上双列。

Floral organ determination is best explained by the ABCDE model postulated by genetic studies of Arabidopsis thaliana. Sepals are determined by A and E class genes; petals are determined by A, B, and E; stamens by B, C, and E; and carpels by C and E class genes. A, B, C, and E class gene lineages are known having duplicated several times during the evolution of angiosperms. One of the noted major duplication events occurred in the origin of the early angiosperms, leading to the formation of subgroups of B/C/D/E class. Another one occurred near the basal eudicots and gave rise to further subgroups in A/B/C/D/E class genes among core eudicots. The phylogenetic position of the family Buxaceae is located right where the second major duplication of ABCDE genes might have occurred, which is supported by multiple gene (nuclear 18S rDNA, chloroplast rbcL and atpB) phylogenetic analyses.

目前经由模式植物阿伯芥的研究，建花部器官决定基因的调控，即花萼由A、E 群基因共同决定，花瓣由A、B、E 群基因，雄蕊由B、C、E 群基因，而心皮由C 和E 群基因决定。A、B、C、E 四群基因在被子植物的演化过程中发生过次的复制事件，其中比较重要的一次发生在早期被子植物演化出之时，形成B/C/D/E 群基因的次系群；另一次复制事件则发生在真双子植物基群附近，形成仅於核心真双子植物的A/B/C/D/E 群基因之次系群。

Ovary superior, globose; carpels 1 to many, free or connate; ovule solitary in each carpel, basal, campylotropous.

子房上位，球状；心皮1到很多，离生或合生；胚珠单生在每心皮，基部，。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
