The sequence analysis revealed that the as1 gene encodes a myb protein , which is a candidate transcription factor . in as1 and as2 mutants , the polarity formation in leaves is defective . cell differentiation along abaxial - adaxial , proximal - distal and media - lateral axes all shows an insufficient fashion 通過掃描電鏡、干涉相差顯微鏡、組織切片、過量表達等手段研究了as1和as2的功能，包括觀察觀察突變體的組織、細胞結構及早期發育狀況，同時采用gus表達、 rt - pcr 、原位雜交、 northern等手段分析基因的表達情況。
In this paper the floral ontogeny and the ovary development of rivina humilis l . were observed . the results showed that ( 1 ) the tepal primordia initiated in 2 / 5 spirals . the abaxial one initiated first , then the adaxial one , finally the lateral two initiated nearly simultaneously . the third one initiated on the position near the first tepal , and there is a gap between itself and the second tepal . ( 2 ) the 4 stamineal primordia initiated in one whorl at the same time . ( 3 ) the carpellary primordium initiated from the abaxial side of flower primordium ; the carpellary primordium grew upwards and towards axis after it was formed , therefore an elliptic orifice was formed at the adaxial position of ovary , which was the remainder of the mouth of ovary before the ovary was fused completely . with the ovary maturing , the orifice was narrowed because of the ovary growth , at last fused completely . the gynoecium is composed of a single carpel . ( 4 ) in the series developmental sections of ovary , the ovular primordium was initiated on the adaxial meristem when the mouth of ovary was formed 對數珠珊瑚的花器官發生和子房的發育過程進行了觀察.結果表明: ( 1 )數珠珊瑚花被呈2 / 5螺旋狀發生,遠軸側的1枚先發生,其次為近軸側的1枚發生,最后側方的2枚花被幾乎同時發生,第3枚花被在靠近第1枚的位置發生,第2枚和第3枚之間有1個空隙; ( 2 ) 4枚雄蕊是同時發生的; ( 3 )心皮發生于分生組織的遠軸側,心皮原基形成后,向上向軸生長,在子房成熟前在近軸側非正中位形成1個孔,該孔為心皮最終愈合前的殘跡,到子房成熟時,因子房的生長孔被擠壓縮小,在進一步的生長過程中愈合.子房由1枚心皮構成; ( 4 )從子房發育過程的切片看,該植物的胚珠是在子房發生后不久發生的,子房上的圓孔形成時,從近軸側的分生組織發生胚珠原基,由胚珠原基分化出珠被與珠心
Leaves thick leathery , obovate - lanceolate , obovate or oblong - lanceolate , 4 - 12 cm long and 2 - 3 . 5 cm wide , apex rounded , sometimes emarginated , base cuneate , abaxial surface thinly covered with a grayish to fawn indumentum at first , later glabrescent ; petiole 1 - 1 . 5 cm long , glabrescent 葉厚革質，倒卵狀披針形、倒卵形或長圓狀披針形，長4 - 12厘米，寬2 - 3 . 5厘米，頂端近圓形，有時微缺，基部楔形，下面初時薄被灰白色或淡土黃色叢卷毛，后近無毛；葉柄長1 - 1 . 5厘米，后近無毛。
The waves should be sheared waves for the anisotropic aeo device and longitudinal waves for the isotropic aeo device . geometrical relationships of anisotropic acousto - optic effect in ln crystal and kdp crystals are studied by tangent - match condition . curves of incident angle vs . abaxial angle , diffractive angle vs . abaxial angle , extreme frequency vs . abaxial angle and acousto - optic merit vs . incident angle vs . abaxial angle are systematically gained and the design parameters are also calculated 利用相切-匹配條件法研究了鈮酸鋰晶體及kdp晶體的反常聲光互作用幾何關系,系統地得到了以離軸角為自變量的各參數的計算公式及相應的關系曲線,通過數值分析方法給出了聲光優值隨中心頻率的變化曲線并給出了器件的設計參數。
Flower - heads narrowly campanulate , 16 - 19 mm long , ca . 6 mm across , usually 2 - 4 in terminal clusters ; peduncle 2 - 8 mm ; involucral bracts ca . in 7 series , ribbed on abaxial surface , apex spiny 葉互生，卵形，長3 - 5 . 5厘米，寬2 - 4厘米，先端短尖，基部近截形，邊緣具疏齒，兩面被長柔毛，具基出脈3條；葉柄長3 - 5毫米。
Early leaf development is artificially divided into three main stages : the initiation of leaf primordium , the establishment of leaf adaxial - abaxial polarity , and the expansion of leaf blade 早期葉片發育包括三個主要過程：葉原基的起始，葉片腹背性的建立和葉片的延展。
Examples include certain species of lycopodium and selaginella , which have two rows of lateral leaves and one or two rows of smaller abaxial or adaxial leaves 例如石松屬和卷柏屬，植物體上具有雙行較大的側生葉，還有1行或2行較小的生于近軸面或遠軸面的葉。
Description : evergreen trees , up to 25 m high ; twigs , buds , petioles , abaxial surfaces of leaves and peduncles covered with yellowish brown rigid hairs 形態特徵：常綠喬木，高達25米；小枝、芽、葉柄、葉背和花梗均被黃棕色糙伏毛。
