Seed germination and dormancy are complex phenomena that are controlled by many genes and environmental factors. Such genes are indicated by phytohormones that interact with each other, and may cause dormancy or promote seed germination. The objective of this study was to investigate gene expression associated with the biosynthetic pathways of abscisic ac.. Read More»

γ-tocopherol methyltransferase is an important rate-limiting enzyme involved in tocopherol biosynthesis. The full-length cDNA encoding γ-tocopherol methyltransferase (designated as LsTMT) was cloned from Lactuca sativa for the first time by rapid amplification of cDNA ends and characterized by means of quantitative..

Tocopherol cyclase is a rate-limiting enzyme involved in tocopherol biosynthesis. The full-length cDNA encoding tocopherol cyclase (designated as LsTC) was cloned from lettuce (Lactuca sativa) for the first time by rapid amplification of cDNA ends (RACE) and characterized by means of quantitative RT-PCR. The full-length cDNA o.. Read More»

Resistance to the root-knot nematodes Meloidogyne spp. would be a valuable attribute of lettuce Lactuca sativa L. cultivars grown in tropical regions. The looseleaf lettuce ‘Grand Rapids’ is resistant to both M. incognita and M. javanica. Resistance to M. incognita has a high heritability, under the control of a si.. Read More»
