Isolation and functional characteristics of the fungus Hypoxylon spp. Sj18 with biocontrol potential.

A fungus with biocontrol potential was isolated from the roots of hickory trees. The strain named sj18 was classified as a member of the genus Hypoxylon (Hypoxylaceae) after multigene phylogenetic analysis (beta-tubulin gene, internal transcribed spacer, 28S large subunit ribosomal RNA gene, and RNA polymerase II subunit gene). The strain grew well on a PDA with an optimum temperature range between 32 and 34 °C.

A novel sunshine duration-based photothermal time model interprets the photosensitivity of flower maturity of pecan cultivars.

Although it is well-known and established that light plays important roles in plant development, up to now, there is no substantial improvements in how to deal with the light factor of spring phenology under natural condition. By monitoring the local meteorologic data and mature dates of two types (male and female) of flower from four pecan cultivars during 9 years, it was found that the complementary pattern of growing degree day and sunshine duration helped to maintain a threshold of driving force related to the maturity of pecan flower during 9 years. A novel photothermal time model based on the linear combination of growing degree day and sunshine duration was then proposed and validated to interpret the variance of mature dates of pecan cultivars.

Identification and characterization of two bamboo (Phyllostachys praecox) AP1/SQUA-like MADS-box genes during floral transition.

Bamboo (Bambusoideae) is by far the largest member of the grass family Poaceae, which is vital to the economy of many countries in the tropics and subtropics. However, the mechanism of flowering of bamboo (Phyllostachys praecox) is still unknown. In this study, we isolated two novel genes from P.

New available SCAR markers: potentially useful in distinguishing a commercial strain of the superior type from other strains of Lentinula edodes in China.

At present, more than 100 strains of Lentinula edodes are cultivated on a commercial scale in China. A simple, reliable, and effective method to distinguish some commercial strains of the superior type from other commercial strains is very important for the Lentinula industry. In this study, 23 commercial strains of L.

Molecular cloning, expression analyses and primary evolution studies of REV- and TB1-like genes in bamboo.

Most cultured bamboos are perennial woody evergreens that reproduce from rhizomes. It is unclear why some rhizome buds develop into aerial bamboo shoots instead of new rhizomes. REVOLUTA (REV)-like Class III homeodomain leucine-zipper (HD-Zip) proteins and TEOSINTE BRANCHED1 (TB1)-like transcription factors have been shown to play regulatory roles in meristem initiation and outgrowth.
