A Tobacco Homolog of DCN1 is Involved in Cellular Reprogramming and in Developmental Transitions [PDF]
Plant proteomes show remarkable plasticity in reaction to environmental challenges and during developmental transitions. Some of this adaptability comes from ubiquitin-mediated protein destruction regulated by cullin-RING E3 ubiquitin ligases (CRLs ...

Phosphatidic acid counteracts S-RNase signaling in pollen by stabilizing the actin cytoskeleton [PDF]
S-RNase is the female determinant of self-incompatibility (SI) in pear (Pyrus bretschneideri). After translocation to the pollen tube, S-RNase degrades rRNA and induces pollen tube death in an S-haplotype-specific manner. In this study, we found that the

Differences in the genetic structure of citrus triploid hybrids recovered from 2x X 2x and 4x X 2x sexual hybridizations [PDF]
Citrus triploid hybrids can be recovered by 2x X 2x hybridisations as a consequence of the formation of 2n gametes or by interploid hybridisation. Most of the 4x parents used in our program are doubled-diploid (DD), also known as autotetraploid.

Identification of self-incompatibility alleles and pollen incompatibility groups in sweet cherry by PCR based s-allele typing and controlled pollination [PDF]
A total of 17 pollen incompatibility groups in sweet cherry (Prunusavium L.) were identified among 46 accessions by PCR based S-alleletyping analysis and by controlled test pollinations.

Genetic diversity and structure of the portuguese pear (Pyrus communis L.) germplasm [PDF]
A rich heritage of traditional pear varieties is kept in national Portuguese collections. Out of these varieties, “Rocha” dominates national pear production.

Berry fruits produced by Vaccinium (Ericaceae) plants are small but have a signature flavor and have become increasingly popular in the 21st century. However, self-incompatibility (SI) results in a relatively low fruit-set ratio and reduced fruit quality

Domain specific interaction of S-RNase binding protein with the stylar 120 kDA glycoprotein in nicotiana [abstract] [PDF]
only availableThrough the process of evolution, many flowering plants have developed a biochemical mechanism to prevent self-pollination and pollination by closely related plants.

Une activation possible de l’allèle Sf chez l’amandier [PDF]
Self-compatibility has become the primary objective of most almond (Prunus amygdalus Batsch) breeding programmes in order to avoid the problems related to the gametophytic self-incompatibility (GSI) system present in almond, as in other species of the ...

Molecular modeling of RNases from almond involved in serlf-incompatibility [PDF]
Gametophytic self-incompatibility (GSI) is a natural mechanism in flowering plants, including almond and other fruit tree species, to prevent inbreeding and promote outcrossing. It is typically under the control of a specific locus, known as the S-locus,
