Citrus is a genus with gametophytic self-incompatibility, which prevents fertilization by self-pollination. Polyamines (PAs), as a class of active small molecules, widely participate in various cellular activities. To investigate the effects of the changes in PA contents [putrescine, spermidine (SPD), and spermine] on pollen tube growth in self-incompatible (SI) plants, we cultured pollen of Citrus maxima ‘Banpeiyu’ and C. tamurana ‘Hyuganatsu’ in a Citrus mature pollen culture system and detected the PA content changes in pollen by high-performance liquid chromatography (HPLC) analysis during germination and after treatment with crude protein extracts of compatible or incompatible styles. We profiled the PA content changes during the germination course in pollen of ‘Banpeiyu’ and ‘Hyuganatsu’ by HPLC, and identified increases of free and perchloric-acid-insoluble SPD contents in pollen tubes in the incompatible treatment. Exogenous SPD treatment obviously increased the SPD contents in the pollen tube, inhibited pollen tube elongation, and resulted in some abnormal morphological alterations, such as tip inflation, tube content leakage and tip twist, which were observed in both ‘Banpeiyu’ and ‘Hyuganatsu’ pollen tubes exposed to incompatible treatment. This finding implied that SPD might participate in the SI response in Citrus.

Plant shoot organs such as stems, leaves and flowers are derived from specialized groups of stem cells organized at the shoot apical meristem (SAM). Organogenesis involves two major processes, namely cell proliferation and differentiation, whereby the former contributes to increasing the cell number and the latter involves substantial increases in cell volume through cell expansion. Co-ordination between the above processes in time and space is essential for proper organogenesis. To identify regulatory factors involved in proper organogenesis, heavy-ion beam-irradiated de-etiolated (det) 3-1 seeds have been used to identify striking phenotypes in the A#26-2; det3-1 mutant. In addition to the stunted plant stature mimicking det3-1, the A#26-2; det3-1 mutant exhibited stem thickening, increased floral organ number and a fruit shape reminiscent of clavata (clv) mutants. DNA sequencing analysis demonstrated that A#26-2; det3-1 harbors a mutation in the CLV3 gene. Importantly, A#26-2; det3-1 displayed cracks that randomly occurred on the main stem with a frequency of approximately 50%. Furthermore, the double mutants clv3-8 det3-1, clv1-4 det3-1 and clv2-1 det3-1 consistently showed stem cracks with frequencies of approximately 97, 38 and 35%, respectively. Cross-sections of stems further revealed an increase in vascular bundle number, cell number and size in the pith of clv3-8 det3-1 compared with det3-1. These findings suggest that the stem inner volume increase due to clv mutations exerts an outward mechanical stress; that in a det3-1 background (defective in cell expansion) resulted in cracking of the outermost layer of epidermal cells.
