【正文】 color bar, a linear scale is used and ‘‘normal’’ represents the template value used for optimization A putational model for 3D patterning of gene expressions in the SAM. Three Arabidopsis AIL/PLT genes act in bination to regulate shoot apical meristem function Mudunkothge JS and KrizeBA. Plant Journal 2023, doi: A balance between stem cell renewal and an production is required for continued meristem function. The class I KNOTTEDlike (KNOX) homeodomain protein SHOOT MERISTEMLESS (STM) acts within the meristem to promote cell division and suppress differentiation. Endrizzi K et al. Plant J. 10, 967–979 The CLAVATA (CLV1, CLV2 and CLV3) and WUSCHEL (WUS) proteins act in a second pathway to maintain a specified number of stem cells within the meristem. . Barton / Developmental Biology 341 (2023) 95–113 ANT, AIL6/PLT3 and AIL7/PLT7 encode related proteins of the Arabidopsis AIL/PLT family, an eightmember subfamily of AP2/ERF transcription factors. ANT and AIL6 have partially redundant roles in several aspects of shoot and flower development, including lateral an growth, floral meristem initiation and floral patterning AIL6 together with PLT1, PLT2 and BBM/PLT4 specifies root development, and in bination with AIL5/PLT5 and AIL7 controls shoot phyllotaxis. Members of the AIL/PLT gene family also regulate meristem development. ANT, AIL6 and AIL7 mRNA expression in vegetative meristems and characterization of ant ail6 ail7 triple mutant plants ant ail6 ail7 triple mutant plants have meristem defects Expression of the meristem regulators CLV3, WUS and STM and the lateral an marker ANT are altered in 7dayold ant ail6 ail7 seedlings. 靜夜四無(wú)鄰，荒居舊業(yè)貧。在 CLV2的跨膜區(qū)域含有帶電荷的氨基酸 , 它與受體激酶跨膜區(qū)域之間的電荷作用能促使異二聚體的形成。此外 , 它還含有一個(gè)疏水性的跨膜域和一個(gè)存在于胞質(zhì)內(nèi)的激酶域 。在這個(gè)過(guò)程中CLV (CLV CLV CLV3)基因起調(diào)節(jié)作用。 ?WUS通過(guò)與轉(zhuǎn)錄輔阻遏蛋白 WSIP1和 WSIP2結(jié)合 , 抑制參與干細(xì)胞分化過(guò)程中的基因表達(dá) , 因而干細(xì)胞能保持其多能性的特征。 WUS的表達(dá)足以誘導(dǎo)干細(xì)胞特征基因CLV3在其上方的細(xì)胞中表達(dá)并賦予它們干細(xì)胞特征 。 ?
