Abstract

Abscission, or organ separation, is accompanied by a marked increase in hydrolases, which are responsible for the degradation of the middle lamella and the loosening of the primary cell wall surrounding cells in the separation layer. We recently reported on the cloning of a tomato (Lycopersicon esculentum) polygalacturonase (PG) cDNA, TAPG1, expressed during leaf and flower abscission. In addition to TAPG1, we have cloned two more PG cDNAs (TAPG2 and TAPG4) that are also expressed during leaf and flower abscission. The peptide sequences for the three abscission PGs are relatively similar (76-93% identity) yet different from the those of tomato fruit PG (38-41% identity). None of the three abscission PG mRNAs are expressed in fruit, stems, petioles, or anthers of fully open flowers. An RNase protection assay revealed that all three PGs are expressed in leaf and flower abscission zones and in pistils of fully open flowers. TAPG4 mRNA is detected much earlier than TAPG1 and TAPG2 mRNA during both leaf and flower abscission.

摘要

脱落，即器官分离，伴随着水解酶的显著增加，这些水解酶负责中层薄片的降解以及分离层中围绕细胞的初生细胞壁的松弛。我们最近报道了一个在叶片和花朵脱落过程中表达的番茄（Lycopersicon esculentum）多聚半乳糖醛酸酶（PG）cDNA，即TAPG1的克隆。除了TAPG1，我们还克隆了另外两个也在叶片和花朵脱落过程中表达的PG cDNA（TAPG2和TAPG4）。这三种脱落相关PG的肽序列相对相似（同一性为76 - 93%），但与番茄果实PG的肽序列不同（同一性为38 - 41%）。这三种脱落相关PG的mRNA在果实、茎、叶柄或完全开放花朵的花药中均不表达。核糖核酸酶保护分析表明，所有这三种PG在叶片和花朵脱落区以及完全开放花朵的雌蕊中均有表达。在叶片和花朵脱落过程中，TAPG4 mRNA的检测时间比TAPG1和TAPG2 mRNA早得多。
