The broad objective of this research is to study the effect warm stratification on Cycas revoluta zygotic embryos length, seed germination and plant development. Four treatments were applied seeds. Our results showed that seeds storage at room temperature or 30°C improved significantly length. Moreover, time was reduced with stratification. highest percentage obtained treated for 2 months while...

A novel lectin was isolated from leaves of the Japanese cycad, Cycas revoluta Thunb. (gymnosperm), and its characteristics including amino acid composition, molecular mass, carbohydrate binding specificity and partial amino acid sequences were examined. The inhibition analysis of hemagglutinating activity with various sugars showed that the lectin has a carbohydrate-binding specificity similar ...

Class III homeodomain leucine zipper (HD-ZIP III) transcription factors regulate critical developmental programs in plants; these include leaf polarity, polarity along the shoot-root axis, and stem cell specification and proliferation. One of the defining features of HD-ZIP III proteins is the presence of a Per-ARNT-Sim-like (PAS-like) MEKHLA domain at the C terminus. PAS-like domains are known...

BACKGROUND Shoots of all land plants have a radial pattern that can be considered to have an adaxial (central)-abaxial (peripheral) polarity. In Arabidopsis, gain-of-function alleles of PHAVOLUTA and PHABULOSA, members of the class III HD-ZIP gene family, result in adaxialization of lateral organs. Conversely, loss-of-function alleles of the KANADI genes cause an adaxialization of lateral organ...

Melicope balgooyi, a new species of Melicope (Rutaceae) is described. It is known only from the Austral Islands in the South Pacific (French Polynesia). However, it is not closely related to the other two species previously known from the Austral Islands, which are part of Melicope section Vitiflorae. The new species belongs to Melicope section Melicope and is most closely related to species fr...

A variety of stock (Matthiola ilzcana R. Br.) known as Snowflake has been shown by FROST (1919) to produce frequent mutants of at least eight distinct kinds. These mutant forms are genetically inconstant, part of the progeny always being normals. These forms have been determined (FROST and MANN 1924, and papers in preparation) to be trisomic. Within, the variety Snowflake, all plants cytologic...

Secondary growth and the development of woody tissue is a key process in the formation of woody biomass. The gene family of Class III HDZip genes has been shown in the herbaceous Arabidopsis model to play a central role in regulating polarity and vascular development. While Arabidopis is a poor model for investigating processes of wood formation, in this project all poplar Class III HDZip genes...
