Ethylene-induced abscission in leaf and fruit explants of peach involves different enzymes. In leaves abscission is accompanied by increased occurrence of cellulase forms differing in isoelectric point (pI 6.5 and 9.5). A polypeptide with a molecular mass of 51 kDa gives in a western blot a strong cross-reaction with an antibody raised against a maturation cellulase from avocado fruit. Cellulase activity is also found in abscising fruit explants but the amount is very low compared to that of… 
Differential ethylene-inducible expression of cellulase in pepper plants
TLDR
Differences in ethylene inducibility and molecular structure suggest different physiological roles for cellulase in pepper plants.
Cloning of a tomato polygalacturonase expressed in abscission
TLDR
The identification of cDNAs that encode abscission-specific PG provide and additional tool to study the regulation of abscissions and cell wall dissolution in separation layer cells.
Temporal and Spatial Expression of a Polygalacturonase during Leaf and Flower Abscission in Oilseed Rape and Arabidopsis1
TLDR
Characterization of these PG genes revealed that they had substantial homology within both the coding regions and in the 5′-upstream sequences, and this fragment was sufficient to drive expression of these reporter genes in the AZs at the base of the anther filaments, petals, and sepals.
Biochemical and molecular aspects of fruitlet abscission
Fruitlet abscission during fruit development is due to the activation ofpre-differentiated abscission zones (AZs) located between twig andpedicel, and/or pedicel and pericarp. Major advances on
Soybean Endo-β-Mannanase GmMAN1 Is Not Associated with Leaf Abscission, but Might Be Involved in the Response to Wounding
TLDR
It is concluded that the soybean endo-β-mannanase GmMAN1 is not associated with leaf abscission, but might be involved in the response to wounding.
Calcium effects on mediating polygalacturonan activity by mRNA expression and protein accumulation during tomato pedicel explant abscission
TLDR
It is suggested that Ca delays tomato pedicel explants abscission by mediating PG activity at both the transcriptional and translational levels.
Characterization of an Endo-p-l , 4-Glucanase Gene lnduced by Auxin in Elongating Pea Epicotyls '
A gene (EGLI) encoding an endo-p-l,4-~-glucanase (EGase, EC 3.2.1.4) of pea (Pisum sativum) has been cloned and characterized. EGL 1 encodes a 486-amino acid polypeptide, including a 24-mer putative
An endo-1,4-β-glucanase expressed at high levels in rapidly expanding tissues
TLDR
Accumulation of Ce14 mRNA was found to be correlated with rapid cell expansion in pistils, hypocotyls and leaves, suggesting that Ce14 RNA accumulation may be promoted directly or indirectly by ethylene.
Isolation and characterization of a gene encoding endo-β-1,4-glucanase from pepper (Capsicum annuum L.)
TLDR
A direct role for ethylene in regulating PCEL1 expression is shown by the exclusive induction, in immature green fruit, of the 1.7 kb transcript in response to prolonged high-level exposure to ethylene - a pattern of expression not observed in fruit development on the vine.

Polygalacturonase expression during leaf abscission of normal and transgenic tomato plants
TLDR
The results indicate that the PG protein in abscission zones of tomato is different from that in the fruit, and that the gene coding for this protein may also be different.

TLDR
Ethylene is required not only to initiate abscission and cellulase gene expression but also to maintain continued accumulation of cellulase mRNA.

Changes in Two Forms of Membrane-Associated Cellulase during Ethylene-Induced Abscission.
TLDR
There is no conversion from the acidic cellulase to thebasic cellulase and it is suggested that the acidic and basic cellulase isoenzymes are proteins derived from two different genes.

TLDR
Time course studies indicate that while the increase in measurable cellulase activity in tissue which is actively undergoing abscission was due primarily to the appearance of cellulase 9.5, this form of the enzyme cannot be removed by vacuum infiltration until after the breakstrength of the abscissions zone has decreased nearly to zero.

Structural and biochemical aspects of peach fruit abscission (Prunus persica L. Batsch)
TLDR
The physiological drop of immature fruits was studied in relation to the activation of the abscission zone located between the fruit and the receptacle and indicated that both enzymes were present as isoenzymes whose patterns were affected by embryoctomy and 2-chloroethylphosphonic acid treatments.
Expression of a chimeric polygalacturonase gene in transgenic rin (ripening inhibitor) tomato fruit results in polyuronide degradation but not fruit softening.
TLDR
It is suggested that this degradation of cell wall polyuronide degradation is not sufficient for the induction of softening, elevated rates of ethylene biosynthesis, or lycopene accumulation in rin fruit.

TLDR
Application of purified tomato polygalacturonase isoenzymes to mature green fruit tissue duplicated the changes in the cell wall noted during normal ripening, which were not consistent with the suggestion that ripening is a ;senescence' phenomenon.
