Barley aleurone layers synthesize and secrete several proteases in response to gibberellic acid (GA3). Two major cysteine proteinases designated EP-A (37,000 M(r)) and EP-B (30,000 M(r)) have been described [Koehler and Ho (1988). Plant Physiol. 87, 95-103]. We now report the cDNA cloning of EP-B and describe the post-translational processing and hormonal regulation of both cysteine proteinases...

The knowledge about aspects related to seed germination are extremely important the propagation of Passiflora species. Considering diversity species and need studies that can elucidate process seeds this study aimed was evaluate methods overcome dormancy in two (P. morifolia P. cincinnata) by pre-germinative treatments as physical scarification, immersion gibberellic acid (GA3) Promalin® (GA4+...

Gladiolus is an important marketable cut flower, especially valued for use in floral arrangements. We assessed the effects of two different methods of application (foliar spray and drench) and various concentrations of gibberellic acid (GA3), salicylic acid (SA), mival (MI) and krizatcin (KR) on vegetative and reproductive features of Gladiolus hybridus. The experiment was planned in a factoria...

taxus chinensis var. mairei is a rare and endangered medicinal plant species distributed in china. in order to promote fast propagation and preserve the natural resources, conditions for in vitro germination and seedling development of embryos of t. chinensis var. mairei from anhui or zhejiang were investigated. results showed that in vitro germination rate of excised embryos cultured under 14 ...

Soil lead (Pb) contamination is a major environmental and public health risk. Switchgrass (Panicum virgatum), second-generation biofuel crop, potentially useful for the long-term phytoremediation phytoextraction of Pb contaminated soils. We evaluated efficacy coordinated foliar application plant growth regulators soil fungicide chelator in order to optimize phytoextraction. Plants were grown cu...

In China, the wild population of Nanjing Linden (Tilia miqueliana M.) is experiencing a drastic decline, primarily due to high levels empty seeds. This study aimed measure biochemical and physiological changes during fruit seed development in T. determine developmental mechanism. The weight method photosynthetic respiration were used biological aspects both fruits embryos, while transmission el...

Limes (Citrus aurantifolia Swingle) have a short postharvest life. Therefore, effective treatments increasing storage life to lengthen the time that produce remains fresh is desirable. This study evaluated effects of 1-methylcyclopropene (1-MCP), gibberellic acid (GA3), and Aloe vera on lime fruit quality. The optimum individual 50% coating, 300 mL·L−1 GA3, 750 nL·L−1 1-MCP were identified as m...

P. aegyptiaca is one of the most destructive root parasitic plants worldwide, causing serious damage to many crop species. Under natural conditions P. aegyptiaca seeds must be conditioned and then stimulated by host root exudates before germinating. However, preliminary experiments indicated that TIS108 (a triazole-type inhibitor of strigolactone) and fluridone (FL, an inhibitor of carotenoid-b...
