Silencing SlGID2, a putative F-box protein gene, generates a dwarf plant and dark-green leaves in tomato

Fortunella spp., Kumquat (FOR300/FR368) Many people find kumquat trees attractive and useful yard specimens. Their dark green leaves and contrasting bright orange fruits give them ornamental quality, and their relatively small size makes them easy to care for once they’re established. Because kumquats generally require less care than other citrus trees, they may be a good choice for gardeners with less time or experience, but who still desire an attractive and tasty citrus tree. If space is an issue, kumquats also do well in containers as long as they receive proper sunlight and watering. This 2-page fact sheet was written by Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop, and published by the UF Department of School of Forest Resources and Conservation, July 2012. http://edis.ifas.ufl.edu/fr368

Litchi trees flower at the apex of terminal shoots. Flowering is affected by the maturity of terminal shoots before growth cessation occurs during the winter. In this study, we focused on changes of flowering in three important cultivars, Guiwei, Feizixiao, and Huaizhi, from Dec. 2012 to Mar. 2013 under natural winter conditions. Flowering rate, carbohydrate accumulation, and expression of the flowering-related genes were determined at three different developmental stages of terminal shoots with dark green, yellowish green and yellowish red leaves, respectively. The results showed that the total soluble sugar and starch contents in the dark green leaves were the highest, whereas those in the yellowish red leaves were the lowest. Trees with dark green terminal shoots had the highest flowering rates, whereas those with yellowish green or yellowish red shoots had relatively lower flowering rates. SPAD was highest in dark green leaves and lowest in yellowish red leaves at the start of the trial. The SPAD value of yellowish red leaves slightly increased but did not reach the levels of the dark green leaves, whereas levels of the other leaf stages remained fairly constant. Expression level of the litchi homolog FLOWERING LOCUS C (LcFLC), the floral inhibitor in yellowish red leaves, increased from 16 Jan., whereas that in dark green leaves declined to a level lower than the yellowish red leaves on 4 Feb. Expression level of the litchi homolog CONSTANTS (LcCO), the floral promoter in dark green leaves, was higher than that of yellowish red leaves before 26 Jan. Expression level of the litchi homolog FLOWERING LOCUS T 2 (LcFT2), encoding florigen, was higher in dark green leaves than in the other two leaf types. Our results suggest that terminal shoots should be matured and leaves should turn green for successful flowering. Mature leaves had higher expression levels of the floral promoter and florigen. In litchi production, leaves of the terminal shoots (potential flowering branches) should be dark green during floral induction and differentiation stages, and winter flushes should be removed or killed.

The leaves of Acer negundo L. var. odessanum (H. Rothe), if permanently exposed to strong sunlight, do not green, but remain yellow and finally become bleached. In yellow leaves the plastids contain single thylakoids and no grana. In plastids of bleached leaves, however, only vesicles are present. The concentration of chlorophylls and photosynthetic activity are much lower in those leaves than in the green ones. If the illumination is reduced (e.g. by shading) both the yellow and the bleached leaves become greenish, and even fully green after a few days at a sufficiently low light intensity. The plastids of yellow-green leaves contain small grana. In dark green leaves the thylakoid system of the chloroplasts is normally developed forming true grana, regardless of whether the leaves were originally green, or became green by shading the yellow or bleached ones. Their pigment concentration and photosynthetic activity are also normal. If green leaves are exposed to sunlight they do not yellow or bleach. During a 3-week period the structure of the thylakoid system did not perceivably change, with the exception that large plastoglobules formed in the stroma.

A New Species

The new species Begonia dicressine (sp. nov.) belonging to Begonia section Platycentrum is described. The new species is similar to B. rockii but differs in having petioles with long soft white hairs, plain dark green leaves with irregularly crenate margins, lower surface only with appressed hairs along midrib, and glabrous inflorescences. B. dicressine is distributed in Kachin Province in northern Myanmar in the understory of evergreen and semi-deciduous forests. New records of B. difformis from the same area are also reported, and its distribution and habitat are discussed.

This community service aim to motivate kelompok Tani Gunungpati 03 Kampung Alam Malon and kelompok Tani Gunungpati 02 Nglarang, Gunungpati to start planting Indigofera. Production can be used to fulfill a part of batik natural dye for cheaper. Special target is availability qualified Indigofera with criteria dark green leaves (green bluish) and oval shape with brownish black seed. The target is from 1000 seeds can be generate 1000 qualified plant ready to harvest in 3 months, and next re-harvest in 2 months. Some activities already done such as socialization community service attended by 36 of farmer team and they held active discussion about the use and additional income from planting indigo. Training in make natural dye paste from indigo is given to 15 of farmer team by experienced trainer. The result of this activity were the farmer group be able to cultivate indigofera, built 2 water shelter to drainage indigo plant. The result of seedlings is not satisfied yet because the growth of sprouts were not simultaneously and not applying hormone gibrelin technology so that for next step need revision in raise seeding. The farmer group ca easily harvest their indigofera to make paste for batik dye color

Abstract Background: Brassinosteroids (BRs) are essential hormones that play crucial roles in plant growth, reproduction and response to abiotic and biotic stress. Results: In transgenic Petunia hybrida , resulting in short stature, dark green leaves, and slowed aging.We demonstrate that the exogenous expression of the SAG12-BAS1 gene results in delayed senescence of flowers. SAG12-BAS1 transgenic lines, grown in the vegetative state, exhibited a range of phenotypic changes, including dark green leaves, short stature, delayed senescence, increased flower bud counts, branching, reduced internode lengths, and delayed flowering. SAG12-BAS1 transgenic expression increased the activity of protective enzymes, reduced malondialdehyde content, and increased chlorophyll content and soluble sugar accumulation in plants. Expression of senescence genes was increased in the transgenic Petunia hybrida compared to wild-type plants. Conclusions: Our finding suggests that BAS1 could be used as a potential candidate gene regulate plant flower senescence and prolong flower longevity.
