Rice tillering is a multigenic trait that influences grain yield, but its regulation molecular module is poorly understood. Here we report that OsMADS57 interacts with OsTB1 (TEOSINTE BRANCHED1) and targets D14 (Dwarf14) to control the outgrowth of axillary buds in rice. An activation-tagged mutant osmads57-1 and OsMADS57-overexpression lines showed increased tillers, whereas OsMADS57 antisense...

A field experiment was conducted on soil application of different levels copper (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 kg Cu ha-1) and foliar (0.25% CuSO4 at tillering stage, 0.25% flowering 0.5% stage stage) to test the response rice plants grown in a copperresponsive Typic Haplustalfs Tamil Nadu. The treatment plots were replicated three times randomized block design. growth attributes like plant h...

To further study the characteristics of changes on the molecular level of rice mutants induced in space environment, we analyzed proteins in leaves and seeds of four rice mutants (two high-tillering and two low-tillering) in the 8(th) and 9(th) generations after a 15-day spaceflight, and compared with their ground controls by two-dimentional polyacrylamide gel electrophoresis and reverse phase ...

Plant endophytic bacteria play an important role in plant growth and health. In the context of climate change, the response of plant endophytic bacterial communities to elevated CO2 at different rice growing stages is poorly understood. Using 454 pyrosequencing, we investigated the response of leaf endophytic bacterial communities to elevated CO2 (eCO2) at the tillering, filling, and maturity s...

Prevalence of keratinophilic fungi was observed in paddy field soil during different stages of cultivation viz., transplanting, tillering, milking and maturation. Out of total 76 soil samples, 65 soil samples were found to be positive for the keratinophilic fungi. Fourteen species belonging to a single genus Chrysosporium were isolated through out the cropping season. C. keratinophilum (17.1%) ...

Drought is one of the major limiting factors in wheat production in Pakistan. Five commercial wheat varieties; Chakwal-97, Inqilab-91, Margalla-99, NR-234 and Wafaq2001 were grown in pots in glasshouse. Plants were subjected to three consecutive drought cycles at tillering, pre-anthesis and milky growth stages by withholding water till leaf rolling started. Measurements of physiological respons...

Cereals and grasses adapt their structural development to environmental conditions and the resources available. The primary adaptive response is a variable degree of branching, called tillering in cereals. Especially for heterogeneous plant configurations the degree of tillering varies per plant. Functional-structural plant modeling (FSPM) is a modeling approach allowing simulation of the archi...

Biocontrol agents are critical for pest management in sustainable agriculture. Generalist arthropod predators may hold a great potential as biocontrol because they ubiquitous and consume pests agroecosystems. However, their diet composition over the entire crop season has rarely been quantified, which hinders our ability to assess real field conditions that foster temporal dynamics of alternati...
