Prolonged Expression of a Putative Invertase Inhibitor in Micropylar Endosperm Suppressed Embryo Growth in Arabidopsis
Proper seed development requires coordinated growth among the three genetically distinct components, the embryo, the endosperm, and the seed coat. In Arabidopsis, embryo growth rate accelerates after endosperm cellularization, which requires a chromatin-remodeling complex, the FIS2-Polycomb Repressive Complex 2 (PRC2). After cellularization, the endosperm ceases to grow and is eventually absorb...
متن کامل[Allelopathic effects of cultured Cucurbita moschata root exudates].
By using the techniques of tissue culture, bio-assay and laboratory analysis, this paper studied the effects of the allelopathic chemicals from pumpkin (Cucurbita moschata) roots on the seed germination and seedling growth of pumpkin, wheat (Triticum aestivum), and radish (Raphanus sativus). The pumpkin root was cultured on a sterile B5 media, and the concentrations of macro- and microelements,...
متن کاملSome properties of a cysteine proteinase inhibitor from corn endosperm.
Thougha numberof proteinaceous cysteine proteinase inhibitors (cystatins) of animal origin have long been studied in detail,1* little is well-defined about plant cystatins except for oryzacystatins from rice seeds.2'3) Preceding the studies on oryzacystatins, however, we purified a cysteine proteinase inhibitor from corn.4'5) In this study we carried out amino acid analysis and kinetic studies ...
متن کاملMechanical stress mediated by both endosperm softening and embryo growth underlies endosperm elimination in Arabidopsis seeds.
Seed development in angiosperms demands the tightly coordinated development of three genetically distinct structures. The embryo is surrounded by the endosperm, which is in turn enclosed within the maternally derived seed coat. In Arabidopsis, final seed size is determined by early expansion of the coenocytic endosperm, which then cellularises and subsequently undergoes developmental programmed...
متن کاملA PI3 kinase inhibitor found to activate bestrophin 3.
Bestrophin 3 (Best3), a member of bestrophin Cl channel family, is a CaCl(cGMP) channel candidate in vascular smooth muscle cells. The mechanism for its activation remains unclear. In previous studies, we reported that an autoinhibitory domain ((356)IPSFLGS(362)) existed in Best3 C-terminus and when the autoinhibitory domain was mutated, the Best3 channel was dramatically activated. In this stu...
