Leaves have unique structures, called veins, that transport liquids and nutrients to leaf cells. Veins also carry the products of photosynthesis back to the rest of the tree. A tree leaf has several types of veins. The central one is called the midrib or midvein. Other veins connect to the...
The acquisition of photosynthesis is a fundamental step in the evolution of eukaryotes. However, few phototrophic organisms are unambiguously recognized in the Precambrian record. The in situ detection of metabolic byproducts in individual microfossils is the key for the direct identification of their me...
Syringa pinnatifolia Hemsl. is a shrub belonging to the Oleaceae family. The peeled woody stems and roots of S. pinnatifolia are used in Chinese traditional medicine. This plant has been used for centuries, and modern pharmacological research has reveale
a实际上我们希望有两款产品:一款是带遥控,另一款是带遥控和侧边面板。 In fact we hoped has two section products: One section is the belt remote control, another section is the belt remote control and the side kneading board.[translate]
Why do the cells have to synthesize proteins when we can get proteins from food? What specific microbes play important roles in photosynthesis, and how? How do receptor proteins act like enzymes? How can prokaryotes perform cellular respiration if they do not have mitochondria?
Albinism in shoots of tea plants is a common phenotypic expression which gives the tea infusion a pleasant umami taste. A novel natural albino mutant tea germplasm containing high amino acids content was found and named as ‘Huabai 1’. ‘Huabai 1’ has
two complementary approaches: first, extraction of proteins with peroxisomal targeting sequences from the Arabidopsis genome and bioinformaticanalyses of their subcellular localization, tissue-specific expression and postulated function; and second, proteomic analysis of leaf peroxisomes from Spinacia oleracea L...
the latter’s importance as an electron carrier in photosystem I (PSI) during photosynthesis44. However, the enzymes for specialized 1,4-naphthoquinones biosynthesis downstream of DHNA have not been identified, including that for MNQ biosynthesis. What is currently reported is that lawsone is ...
Of these, two activate and one represses transcription under LL, and it is the joint regulation at these three sites that leads to the observed regulation (Takahashi et al., 2010). In S. elongatus, in addition to photosynthesis-related genes, RpaB binds to the promoters of the sigma ...
After returning to Kunming, capital of Yunnan, with the plant and conducting further studies, they found that the species is a member of the Thismia genus, which doesn't have green leaves and has eschewed photosynthesis in favor of a more unusual nutrient gathering process. Thismia plants, co...
