Pollen tube germination, growth, and guidance (progamic phase) culminating in sperm discharge is a multi-stage process including complex interactions between the male gametophyte as well as sporophytic tissues and the female gametophyte (embryo sac), respectively. Inter- and intra-specific crossing barriers in maize and Tripsacum have been studied and a precise description of progamic pollen tu...
breeding of almond to attain self compatible cultivars is among the objectives followed in almond breeding. early identification of self-compatible genotypes from self-incompatible ones is very important in saving of time and expenses. there are different methods of either classical or molecular nature to recognize self-compatibility in genotypes. in this study, pcr-based method with specific p...
Proteomic analysis of the stigmatic exudate of Lilium longiflorum and Olea europaea led to the identification of 51 and 57 proteins, respectively, most of which are described for the first time in this secreted fluid. These results indicate that the stigmatic exudate is an extracellular environment metabolically active, participating in at least 80 different biological processes and 97 molecula...
Research into molecular mechanisms of self-incompatibility (SI) in plants can be observed representatives various families, including Solanaceae. Earlier studies the S-RNase-based SI petunia (Petunia hybrida E. Vilm.) demonstrate that programmed cell death (PCD) is an factor. These suggest phytohormon cytokinin (CK) putative activator caspase-like proteases (CLPs). In this work, data confirming...
Citrus reproductive biology is complex. One of its characteristic features parthenocarpy that enables seedless fruit production. and self-incompatibility knowledge only partial sometimes discrepant. Increasing such relevant for better managing cultivated varieties improving the selection parents in breeding strategies to recover as mandarins. This work develops an efficient protocol characteriz...
Apple (Malus x domestica) fruit size is dependent on cell division and expansion, processes that are subsequently regulated by plant hormones such as auxins, gibberellins, cytokinins. In this study, we investigated the role of expansion in apple growth identified which two was more deterministic final size. Three cultivars different sizes were selected, namely, “Twenty Ounce” (large-sized), “Ro...
Recent concerns regarding within-crop transgene flow stimulated this research to update natural cross-pollination rates in conventional sowings of modern soybean [Glycine max (L.) Merr.] in the Mississippi Delta. Two experiments were conducted in 2001 and 2002 using two soybean cultivars, "Pace" (white-flowered) and "DP3588" (purple-flowered), selected for their equivalent flowering dates. The ...
In Arabidopsis, the regulation network of the seed maturation program controls the induction of seed dormancy. Wheat EST sequences showing homology with the master regulators of seed maturation, leafy cotyledon1 (LEC1), LEC2 and FUSCA3 (FUS3), were searched from databases and designated respectively as TaL1L (LEC1-LIKE), TaL2L (LEC2-LIKE), and TaFUS3. TaL1LA, TaL2LA and TaFUS3 mainly expressed ...
